Media: Submarine sandwich

A submarine sandwich, commonly known as a sub, hoagie (Philadelphia metropolitan area and Western Pennsylvania English), hero (New York City English), Italian (Maine English), grinder (New England English), wedge (Westchester, NY), or a spuckie (Boston English), is a type of American cold or hot sandwich made from a cylindrical bread roll split lengthwise and filled with meats, cheeses, vegetables, and condiments. It has many different names.

The terms submarine and sub are widespread in the US and not assignable to any certain part, though many of the localized terms are clustered in the northeastern United States.

History and etymology

The Italian sandwich originated in several different Italian American communities in the Northeastern United States from the late 19th to mid-20th centuries. The popularity of this Italian-American cuisine has grown from its origins in Connecticut, Pennsylvania, Delaware, Maryland, New York, New Jersey, Massachusetts, and Rhode Island to most parts of the United States and Canada, and with the advent of chain restaurants, is now available in many parts of the world. Edwin Eames and Howard Robboy identified thirteen different terms for the submarine sandwich in the United States.

Submarine

The use of the term "submarine" or "sub" (after the resemblance of the roll to the shape of a submarine) is widespread in the United States and Canada. While some accounts source the name as originating in New London, Connecticut (site of the United States Navy's primary submarine base) during World War II, written advertisements from 1940 in Wilmington, Delaware, indicate the term originated prior to the United States's entry into World War II.

Fenian Ram submarine, c. 1920

One theory says the submarine was brought to the U.S. by Dominic Conti (1874–1954), an Italian immigrant who came to New York in the late 19th century. He is said to have named it after seeing the recovered 1901 submarine called Fenian Ram in the Paterson Museum of New Jersey in 1928. His granddaughter has stated the following:

My grandfather came to this country circa 1895 from Montella, Italy. Around 1910, he started his grocery store, called Dominic Conti's Grocery Store, on Mill Street in Paterson, New Jersey where he was selling the traditional Italian sandwiches. His sandwiches were made from a recipe he brought with him from Italy, which consisted of a long crust roll, filled with cold cuts, topped with lettuce, tomatoes, peppers, onions, oil, vinegar, Italian herbs and spices, salt, and pepper. The sandwich started with a layer of cheese and ended with a layer of cheese (this was so the bread wouldn't get soggy).

Party sub

Party sub is the name for a particularly long submarine sandwich, usually cut into pieces and served to guests at parties. The longest on record measured 735 meters (2,411 feet, 5 in).

Hoagie

Workers read the Hog Island News

 

Salami, ham and cheeses on a hoagie roll

The term hoagie originated in the Philadelphia area. In 1953, the Philadelphia Bulletin reported that Italians working at the World War I-era shipyard known as Hog Island, where emergency shipping was produced for the war effort, introduced the sandwich by putting various meats, cheeses, and lettuce between two slices of bread. This became known as the "Hog Island" sandwich; shortened to "Hoggies", then the "hoagie".

Dictionary.com offers the following origin of the term hoagie - n. American English (originally Philadelphia) word for "hero, large sandwich made from a long, split roll"; originally hoggie (c. 1936), traditionally said to be named for Big Band songwriter Hoagland Howard "Hoagy" Carmichael (1899–1981), but the use of the word predates his celebrity and the original spelling seems to suggest another source (perhaps "hog"). Modern spelling is c. 1945, and may have been altered by influence of Carmichael's nickname.

The Philadelphia Almanac and Citizen's Manual offers a different explanation, that the sandwich was created by early-twentieth-century street vendors called "hokey-pokey men", who sold antipasto salad, meats, cookies and buns with a cut in them. When Gilbert and Sullivan's operetta H.M.S. Pinafore opened in Philadelphia in 1879, bakeries produced a long loaf called the pinafore. Entrepreneurial "hokey-pokey men" sliced the loaf in half, stuffed it with antipasto salad, and sold the world's first "hoagie".

Another explanation is that the word hoagie arose in the late 19th to early 20th centuries, among the Italian community in South Philadelphia, when "on the hoke" meant that someone was destitute. Deli owners would give away scraps of cheeses and meats in an Italian bread-roll known as a "hokie", but the Italian immigrants pronounced it "hoagie".

Shortly after World War II, there were numerous varieties of the term in use throughout Philadelphia. By the 1940s, the spelling "hoagie" had come to dominate less-used variations like "hoogie" and "hoggie". It is never spelled hoagy. By 1955, restaurants throughout the area were using the term hoagie. Listings in Pittsburgh show hoagies arriving in 1961 and becoming widespread in that city by 1966.

Former Philadelphia mayor (and later Pennsylvania governor) Ed Rendell declared the hoagie the "Official Sandwich of Philadelphia". However, there are claims that the hoagie was actually a product of nearby Chester. DiCostanza's in Boothwyn claims that the mother of DiConstanza's owner originated the hoagie in 1925 in Chester. DiCostanza relates the story that a customer came into the family deli and through an exchange matching the customer's requests and the deli's offerings, the hoagie was created.

Woolworth's to-go sandwich was called a hoagie in all U.S. stores.

Bánh mì sandwiches are sometimes referred to as "Vietnamese hoagies" in Philadelphia.

Hero

New York style meatball hero with mozzarella

The New York term hero is first attested in 1937. The name is sometimes credited to the New York Herald Tribune food writer Clementine Paddleford in the 1930s, but there is no good evidence for this. It is also sometimes claimed that it is related to the gyro, but this is unlikely as the gyro was unknown in the United States until the 1960s.

Hero (plural usually heros, not heroes) remains the prevailing New York City term for most sandwiches on an oblong roll with a generally Italian flavor, in addition to the original described above. Pizzeria menus often include eggplant parmigiana, chicken parmigiana, and meatball heros, each served with sauce.

Grinder

Pastrami grinder

A common term in New England, especially Connecticut and Western Massachusetts, is grinder, but its origin has several possibilities. One theory has the name coming from Italian-American slang for a dock worker, among whom the sandwich was popular. Others say that it was called a grinder because the bread's hard crust required much chewing.

In Pennsylvania, New York, and parts of New England, the term grinder usually refers to a hot submarine sandwich (meatball, sausage, etc.), whereas a cold sandwich (e.g., cold cuts) is usually called a "sub". In the Philadelphia area, the term grinder is also applied to any hoagie that is toasted in the oven after assembly, whether or not it is made with traditionally hot ingredients.

Italian

The term "Italian sandwich" or simply "Italian" is used in Maine. Local folklore claims that a baker named Giovanni Amato invented the Italian in 1899.

A cross-section of an Italian sandwich

The traditional Maine Italian sandwich is prepared using a long, soft bread roll or bun with meats such as salami, mortadella, capocollo or ham along with provolone, tomato, onion, green bell pepper, Greek olives, pickles, olive oil or salad oil, salt and cracked black pepper. Additional ingredients, such as pepperoni, banana pepper, or lettuce may be added to the sandwich. The sandwich is often cut in half to make it easier to handle.

Wedge

The term wedge is used in the New York counties of Dutchess, Putnam, and Westchester, as well as the Connecticut county of Fairfield – four counties directly north of New York City.

Some base the name wedge on a diagonal cut in the middle of the sandwich, creating two halves or "wedges", or a "wedge" cut out of the top half of the bread with the fillings "wedged" in between, or a sandwich that is served between two "wedges" of bread. It has also been said wedge is just short for "sandwich", with the name having originated from an Italian deli owner located in Yonkers, who got tired of saying the whole word.

Spukie

The term spukie ("spukkie" or "spuckie") is unique to the city of Boston and derives from the Italian word spuccadella, meaning "long roll". The word spuccadella is not typically found in Italian dictionaries, which may suggest that it could be a regional Italian dialect, or possibly a Boston Italian-American innovation. Spukie is typically heard in parts of Dorchester and South Boston. Some bakeries in Boston's North End neighborhood have homemade spuccadellas for sale.

Other names

• Blimpie (shaped like a blimp) – from the Hoboken, New Jersey–founded chain, Blimpie
• Gatsby – Cape Town, South Africa
• Po' boy – Louisiana
• Cosmo – Williamsport, Pennsylvania
• Zeppelin or Zep – eastern Pennsylvania
• Smoske – Belgium
• Dagobert – Belgium
• Continental roll ('Conti roll') - Western Australia

Popularity and availability

Rolls filled with condiments have been common in several European countries for more than a century, notably in France and Scotland.

In the United States, from its origins with the Italian-American labor force in the northeast, the sub began to show up on menus of local pizzerias. As time went on and popularity grew, small restaurants, called hoagie shops and sub shops, that specialized in the sandwich began to open.

Pizzerias may have been among the first Italian-American eateries, but even at the turn of the [20th] century distinctions were clear-cut as to what constituted a true ristorante. To be merely a pizza-maker was to be at the bottom of the culinary and social scale; so many pizzeria owners began offering other dishes, including the hero sandwich (also, depending on the region of the United States, called a 'wedge,' a 'hoagie,' a 'sub,' or a 'grinder') made on an Italian loaf of bread with lots of salami, cheese, and peppers.

— John Mariani, America Eats Out, p. 66

Subs or their national equivalents were already popular in many European, Asian, and Australasian countries when late 20th-century franchisee chain restaurants (such as Subway) and fast food made them even more popular and increased the prevalence of the word sub. Many outlets offer non-traditional ingredient combinations.

In the United States, there are many chain restaurants that specialize in subs. Major international chains include Firehouse Subs, Quiznos, Mr. Sub, Jimmy John's, and the largest restaurant chain in the world, Subway. The sandwich is also often available at supermarkets, local delis, and convenience stores. These include Wawa, which annually runs a sub promotional event during the summer called Hoagiefest, and Publix, whose sandwiches are often referred to as "pub subs".

Bánh mì

Alternative names	Vietnamese roll or sandwich, Saigon roll or sandwich
Type	Sandwich
Place of origin	South Vietnam
Invented	1950s
Main ingredients	Vietnamese baguette (also called bánh mì)
Variations	See below
Cookbook: Bánh mì   Media: Bánh mì

In Vietnamese cuisine, bánh mì or banh mi is a short baguette with thin, crisp crust and soft, airy texture. It is often split lengthwise and filled with savory ingredients like a submarine sandwich and served as a meal, called bánh mì thịt. Plain banh mi is also eaten as a staple food.

A typical Vietnamese roll or sandwich is a fusion of meats and vegetables from native Vietnamese cuisine such as chả lụa (pork sausage), coriander leaf (cilantro), cucumber, pickled carrots, and pickled daikon combined with condiments from French cuisine such as pâté, along with red chili and buttery mayonnaise. However, a wide variety of popular fillings are used, from xíu mại (a Chinese cuisine) to even ice cream. In Vietnam, bread rolls and sandwiches are typically eaten for breakfast or as a snack.

The baguette was introduced to Vietnam by the French in the mid-19th century, during the Nguyễn dynasty, and became a staple food by the early 20th century. In the 1950s, a distinctly Vietnamese style of sandwich developed in Saigon, becoming a popular street food, also known as bánh mì Sài Gòn ("Saigon sandwich", "Saigon-style banh mi"). Following the Vietnam War, Overseas Vietnamese popularized the bánh mì sandwich in countries such as Australia, Canada and the United States. In these countries they are commonly sold in Asian bakeries.

Terminology

Bánh mì and bì cuốn

In Vietnamese, the word bánh mì is derived from bánh (which can refer to many kinds of food, primarily baked goods, including bread) and mì (wheat). It may also be spelled bánh mỳ in northern Vietnam. Taken alone, bánh mì means any kind of bread, but it could refer to the Vietnamese baguette, or the sandwich made from it. To distinguish the un-filled bread from the sandwich with fillings, the term bánh mì không ("plain bread") can be used. To distinguish the Vietnamese-style bread from other kinds of bread, the term bánh mì Sài Gòn ("Saigon-style bread") or bánh mì Việt Nam ("Vietnam-style bread") can be used.

A folk etymology claims that the word bánh mì is a corruption of the French pain de mie, meaning soft, white bread. However, bánh or its Nôm form 餅 has referred to rice cakes and other pastries since as early as the 13th century, long before French contact.

History

The word bánh mì, meaning "bread", is attested in Vietnamese as early as the 1830s, in Jean-Louis Taberd's dictionary Dictionarium Latino-Annamiticum. The French introduced Vietnam to the baguette, along with other baked goods such as pâté chaud, in the 1860s, at the start of their imperialism in Vietnam. Northern Vietnamese initially called the baguette bánh tây, literally "Western bánh", while Southern Vietnamese called it bánh mì, "wheat bánh". Nguyễn Đình Chiểu mentions the baguette in his 1861 poem "Văn tế nghĩa sĩ Cần Giuộc". Due to the price of imported wheat at the time, French baguettes and sandwiches were considered a luxury. During World War I, an influx of French soldiers and supplies arrived. At the same time, disruptions of wheat imports led bakers to begin mixing in inexpensive rice flour (which also made the bread fluffier). As a result, it became possible for ordinary Vietnamese to enjoy French staples such as bread. Many shops baked twice a day, because bread tends to go stale quickly in the hot, humid climate of Vietnam. Baguettes were mainly eaten for breakfast with some butter and sugar.

A bánh mì stand in Ho Chi Minh City

Until the 1950s, sandwiches hewed closely to French tastes, typically a jambon-beurre moistened with a mayonnaise or liver pâté spread. The 1954 Partition of Vietnam sent over a million migrants from North Vietnam to South Vietnam, transforming Saigon's local cuisine. Among the migrants were Lê Minh Ngọc and Nguyễn Thị Tịnh, who opened a small bakery named Hòa Mã in District 3. In 1958, Hòa Mã became one of the first shops to sell bánh mì thịt. Around this time, another migrant from the North began selling chả sandwiches from a basket on a mobylette, and a stand in Gia Định Province (present-day Phú Nhuận District) began selling phá lấu sandwiches. Some shops stuffed sandwiches with inexpensive Cheddar cheese, which came from French food aid that migrants from the North had rejected. Vietnamese communities in France also began selling bánh mì.

After the Fall of Saigon in 1975, bánh mì sandwiches became a luxury item once again. During the so-called "subsidy period", state-owned phở eateries often served bread or cold rice as a side dish, leading to the present-day practice of dipping quẩy in phở. In the 1980s, Đổi Mới market reforms led to a renaissance in bánh mì, mostly as street food.

Meanwhile, Vietnamese Americans brought bánh mì sandwiches to cities across the United States. In Northern California, Lê Văn Bá and his sons are credited with popularizing bánh mì among Vietnamese and non-Vietnamese Americans alike through their food truck services provider and their fast-food chain, Lee's Sandwiches, beginning in the 1980s. Sometimes bánh mì was likened to local sandwiches. In New Orleans, a "Vietnamese po' boy" recipe won the 2009 award for best po' boy at the annual Oak Street Po-Boy Festival. A restaurant in Philadelphia also sells a similar sandwich, marketed as a "Vietnamese hoagie".

Since the 1970s Vietnamese refugees from the American War in Vietnam arrived in London and were hosted at community centres in areas of London such as De Beauvoir Town eventually founding a string of successful Vietnamese-style canteens in Shoreditch where bánh mì alongside phở, were popularised from the 1990s.

Bánh mì sandwiches were featured in the 2002 PBS documentary Sandwiches That You Will Like. The word bánh mì was added to the Oxford English Dictionary on 24 March 2011. As of 2017, bánh mì is included in about 2% of U.S. restaurant sandwich menus, a nearly fivefold increase from 2013. On March 24, 2020, Google celebrated bánh mì with a Google Doodle.

A Vietnamese baguette has a thin crust and white, airy crumb. It may consist of both wheat flour and rice flour.

Besides being made into a sandwich, it is eaten alongside meat dishes, such as bò kho (a beef stew), curry, and phá lấu. It can also be dipped in condensed milk (see Sữa Ông Thọ).

Fillings

Assembling a bánh mì

A bánh mì sandwich typically consists of one or more meats, accompanying vegetables, and condiments.

Accompanying vegetables typically include fresh cucumber slices, cilantro (leaves of the coriander plant) and pickled carrots and white radishes in shredded form (đồ chua). Common condiments include spicy chili sauce, sliced chilis, Maggi seasoning sauce, and mayonnaise.

Varieties

Many fillings are used. A typical bánh mì shop in the United States offers at least 10 varieties.

The most popular variety is bánh mì thịt, thịt meaning "meat". Bánh mì thịt nguội (also known as bánh mì pâté chả thịt, bánh mì đặc biệt, or "special combo") is made with various Vietnamese cold cuts, such as sliced pork or pork belly, chả lụa (pork sausage), and head cheese, along with the liver pâté and vegetables like carrot or cucumbers.

Other varieties include:

• Bánh mì bì (shredded pork sandwich) – shredded pork or pork skin, doused with fish sauce
• Bánh mì chà bông (pork floss sandwich)
• Bánh mì xíu mại (minced pork meatball sandwich) – smashed pork meatballs
• bánh mì thịt nguội (ham sandwich)
• Bánh mì cá mòi (sardine sandwich)
• Bánh mì pa-tê (pâté sandwich)
• Bánh mì xá xíu or bánh mì thịt nướng (barbecue pork sandwich)
• Bánh mì chả lụa or bánh mì giò lụa (pork sausage sandwich)
• Bánh mì gà nướng (grilled chicken sandwich)
• Bánh mì chay (vegetarian sandwich) – made with tofu or seitan; in Vietnam, usually made at Buddhist temples during special religious events, but uncommon on the streets
• Bánh mì chả cá (fish patty sandwich)
• Bánh mì bơ (margarine or buttered sandwich) – margarine / butter and sugar
• Bánh mì trứng ốp-la (fried egg sandwich) – contains fried eggs with onions, sprinkled with soy sauce, sometimes buttered; served for breakfast in Vietnam
• Bánh mì kẹp kem (ice cream sandwich) – contains scoops of ice cream topped with crushed peanuts

Notable vendors

Bánh mì sold in Lee's Sandwiches.

Prior to the Fall of Saigon in 1975, well-known South Vietnamese bánh mì vendors included Bánh mì Ba Lẹ and Bánh mì Như Lan (which opened in 1968).

In regions of the United States with significant populations of Vietnamese Americans, numerous bakeries and fast food restaurants specialize in bánh mì. Lee's Sandwiches, a fast food chain with locations in several states, specializes in Vietnamese sandwiches served on French baguettes (or traditional bánh mì at some locations) as well as Western-style sandwiches served on croissants. In New Orleans, Dong Phuong Oriental Bakery is known for the bánh mì bread that it distributes to restaurants throughout the city. After 1975, Ba Lẹ owner Võ Văn Lẹ fled to the United States and, along with Lâm Quốc Thanh, founded Bánh mì Ba Lê. The Eden Center shopping center in Northern Virginia has several well-known bakeries specializing in bánh mì.

Mainstream fast food chains have also incorporated bánh mì and other Vietnamese dishes into their portfolios. Yum! Brands operates a chain of bánh mì cafés called Bánh Shop. The former Chipotle-owned ShopHouse Southeast Asian Kitchen chain briefly sold bánh mì. Jack in the Box offers a "bánh mì–inspired" fried chicken sandwich as part of its Food Truck Series. McDonald's and Paris Baguette locations in Vietnam offer bánh mì.

Alternative names	Philadelphia cheesesteak, Philly cheesesteak
Course	Main course
Place of origin	United States
Region or state	Philadelphia, Pennsylvania
Created by	Pat & Harry Olivieri
Serving temperature	Hot
Main ingredients	Sliced steak, cheese, bread
Variations	Multiple

A cheesesteak (also known as a Philadelphia cheesesteak, Philly cheesesteak, cheesesteak sandwich, cheese steak, or steak and cheese) is a sandwich made from thinly sliced pieces of beefsteak and melted cheese in a long hoagie roll. A popular regional fast food, it has its roots in the U.S. city of Philadelphia, Pennsylvania.

History

The cheesesteak was developed in the early 20th century "by combining frizzled beef, onions, and cheese in a small loaf of bread", according to a 1987 exhibition catalog published by the Library Company of Philadelphia and the Historical Society of Pennsylvania.

Philadelphians Pat and Harry Olivieri are often credited with inventing the sandwich by serving chopped steak on an Italian roll in the early 1930s. The exact story behind its creation is debated, but in some accounts, Pat and Harry Olivieri originally owned a hot dog stand, and on one occasion, decided to make a new sandwich using chopped beef and grilled onions. While Pat was eating the sandwich, a cab driver stopped by and was interested in it, so he requested one for himself. After eating it, the cab driver suggested that Olivieri quit making hot dogs and instead focus on the new sandwich. They began selling this variation of steak sandwiches at their hot dog stand near South Philadelphia's Italian Market. They became so popular that Pat opened up his own restaurant which still operates today as Pat's King of Steaks. The sandwich was originally prepared without cheese; Olivieri said provolone cheese was first added by Joe "Cocky Joe" Lorenza, a manager at the Ridge Avenue location.

Cheesesteaks have become popular at restaurants and food carts throughout the city with many locations being independently owned, family-run businesses. Variations of cheesesteaks are now common in several fast food chains. Versions of the sandwich can also be found at high-end restaurants. Many establishments outside of Philadelphia refer to the sandwich as a "Philly cheesesteak".

Description

Meat

The meat traditionally used is thinly sliced rib-eye or top round, although other cuts of beef are also used. On a lightly oiled griddle at medium temperature, the steak slices are quickly browned and then scrambled into smaller pieces with a flat spatula. Slices of cheese are then placed over the meat, letting it melt, and then the roll is placed on top of the cheese. The mixture is then scooped up with a spatula and pressed into the roll, which is then cut in half.

Common additions include sautéed onions, grilled mushrooms, ketchup, hot sauce, salt, and black pepper.

Bread

In Philadelphia, cheesesteaks are invariably served on hoagie rolls. Among several brands, perhaps the most famous are Amoroso rolls; these rolls are long, soft, and slightly salted. One source writes that "a proper cheesesteak consists of provolone or Cheez Whiz slathered on an Amoroso roll and stuffed with thinly shaved grilled meat," while a reader's letter to an Indianapolis magazine, lamenting the unavailability of good cheesesteaks, wrote that "the mention of the Amoroso roll brought tears to my eyes." After commenting on the debates over types of cheese and "chopped steak or sliced", Risk and Insurance magazine declared, "The only thing nearly everybody can agree on is that it all has to be piled onto a fresh, locally baked Amoroso roll."

Cheese

American cheese, Provolone, and Cheez Whiz are the most commonly used cheeses or cheese products put on to the Philly cheesesteak.

White American cheese, along with provolone cheese, are the favorites due to their mild flavor and medium consistency. Some establishments melt the American cheese to achieve the creamy consistency, while others place slices over the meat, letting them melt slightly under the heat. Philadelphia Inquirer restaurant critic Craig LaBan says, "Provolone is for aficionados, extra-sharp for the most discriminating among them." Geno's owner, Joey Vento, said, "We always recommend the provolone. That's the real cheese."

Cheez Whiz, first marketed in 1952, was not yet available for the original 1930 version, but has spread in popularity. A 1986 New York Times article called Cheez Whiz "the sine qua non of cheesesteak connoisseurs." In a 1985 interview, Pat Olivieri's nephew Frank Olivieri said that he uses "the processed cheese spread familiar to millions of parents who prize speed and ease in fixing the children's lunch for the same reason, because it is fast." Cheez Whiz is "overwhelmingly the favorite" at Pat's, outselling runner-up American by a ratio of eight or ten to one, while Geno's claims to go through eight to ten cases of Cheez Whiz a day.

Variations

• A chicken cheesesteak or chicken Philly is made with chicken instead of beef.
• A mushroom cheesesteak is a cheesesteak topped with mushrooms.
• A pepper cheesesteak is a cheesesteak topped with green bell peppers, hot cherry peppers, long hot peppers, or sweet peppers.

Lactic acid fermentation

From Wikipedia, the free encyclopedia

https://en.wikipedia.org/wiki/Lactic_acid_fermentation

 

One isomer of lactic acid

 

This animation focuses on one molecule of glucose turning into pyruvate then into lactic acid. In the process there is one 6-carbon glucose molecule and 2 NAD+ molecules. 2 phosphates attach to the ends of the glucose molecule, then glucose is split into 2 3-carbon pyruvate precursors. Subsequently, NAD+ molecules are converted into 2 NADH and additional phosphate groups are attached to the carbons. Then ADP comes and takes the phosphates, creating 2 ATP molecules. The pyruvate is turned into 2 lactate molecules, which convert NADH back to NAD+. The process then repeats, starting with another glucose molecule.

Lactic acid fermentation is a metabolic process by which glucose or other six-carbon sugars (also, disaccharides of six-carbon sugars, e.g. sucrose or lactose) are converted into cellular energy and the metabolite lactate, which is lactic acid in solution. It is an anaerobic fermentation reaction that occurs in some bacteria and animal cells, such as muscle cells.

If oxygen is present in the cell, many organisms will bypass fermentation and undergo cellular respiration; however, facultative anaerobic organisms will both ferment and undergo respiration in the presence of oxygen. Sometimes even when oxygen is present and aerobic metabolism is happening in the mitochondria, if pyruvate is building up faster than it can be metabolized, the fermentation will happen anyway.

Lactate dehydrogenase catalyzes the interconversion of pyruvate and lactate with concomitant interconversion of NADH and NAD⁺.

In homolactic fermentation, one molecule of glucose is ultimately converted to two molecules of lactic acid. Heterolactic fermentation, in contrast, yields carbon dioxide and ethanol in addition to lactic acid, in a process called the phosphoketolase pathway.

History

Several chemists discovered during the 19th century some fundamental concepts of the domain of organic chemistry. One of them for example was the French chemist Joseph Louis Gay-Lussac, who was especially interested in fermentation processes, and he passed this fascination to one of his best students, Justus von Liebig. With a difference of some years, each of them described, together with colleagues, the chemical structure of the lactic acid molecule as we know it today. They had a purely chemical understanding of the fermentation process, which means that you can't see it using a microscope, and that it can only be optimized by chemical catalyzers. In 1857, the French chemist Louis Pasteur first described lactic acid as the product of a microbial fermentation. During this time, he worked at the University of Lille, where a local distillery asked him for advice concerning some fermentation problems. Per chance and with the badly equipped laboratory he had at that time, he was able to discover that in this distillery, two fermentations were taking place, a lactic acid one and an alcoholic one, both induced by microorganisms. He then continued the research on these discoveries in Paris, where he also published his theories that presented a stable contradiction to the purely chemical version represented by Liebig and his followers. Even though Pasteur described some concepts that are still accepted today, Liebig refused to accept them. But even Pasteur himself wrote that he was "driven" to a completely new understanding of this chemical phenomenon. Even if Pasteur didn't find every detail of this process, he still discovered the main mechanism of how the microbial lactic acid fermentation works. He was the first to describe fermentation as a "form of life without air."

Although this chemical process had not been properly described before Pasteur's work, people had been using microbial lactic acid fermentation for food production much earlier. Chemical analysis of archeological finds show that milk fermentation uses predate the historical period; its first applications were probably a part of the Neolithic Revolution. Since milk naturally contains lactic acid bacteria, the discovery of the fermentation process was quite evident, since it happens spontaneously at an adequate temperature. The problem of these first farmers was that fresh milk is nearly indigestible by adults, so they had an interest to discover this mechanism. In fact, lactic acid bacteria contain the needed enzymes to digest lactose, and their populations multiply strongly during the fermentation. Therefore, milk fermented even a short time contains enough enzymes to digest the lactose molecules, after the milk is in the human body, which allows adults to consume it. Even safer was a longer fermentation, which was practiced for cheesemaking. This process was also discovered a very long time ago, which is proven by recipes for cheese production on Cuneiform scripts, the first written documents that exist, and a bit later in Babylonian and Egyptian texts. What is interesting is the theory of the competitive advantage of fermented milk products. The idea of this theory is that the women of these first settled farmer clans could shorten the time between two children thanks to the additional lactose uptake from milk consumption. This factor may have given them an important advantage to out-compete the hunter-gatherer societies.^[6]

With the increasing consumption of milk products these societies developed a lactase persistence by epigenetic inheritance, which means that the milk-digesting enzyme lactase was present in their bodies during the whole lifetime, so they could drink unfermented milk as adults too. This early habituation to lactose consumption in the first settler societies can still be observed today in regional differences of this mutation's concentration. It is estimated that about 65% of world population still lacks it. Since these first societies came from regions around eastern Turkey to central Europe, the gene appears more frequently there and in North America, as it was settled by Europeans. It is because of the dominance of this mutation that Western cultures believe it is unusual to have a lactose intolerance, when it is in fact more common than the mutation. On the contrary, lactose intolerance is much more present in Asian countries.

A bottle and glass of Kumis

Milk products and their fermentation have had an important influence on some cultures’ development. This is the case in Mongolia, where people often practice a pastoral form of agriculture. The milk that they produce and consume in these cultures is mainly mare milk and has a long tradition. But not every part or product of the fresh milk has the same meaning. For instance, the fattier part on the top, the "deež", is seen as the most valuable part and is therefore often used to honor guests. Very important with often a traditional meaning as well are fermentation products of mare milk, like for example the slightly-alcoholic yogurt kumis. Consumption of these peaks during cultural festivities such as the Mongolian lunar new year (in spring). The time of this celebration is called the "white month", which indicates that milk products (called "white food" together with starchy vegetables, in comparison to meat products, called "black food") are a central part of this tradition. The purpose of these festivities is to "close" the past year – clean the house or the yurt, honor the animals for having provided their food, and prepare everything for the coming summer season – to be ready to "open" the new year. Consuming white food in this festive context is a way to connect to the past and to a national identity, which is the great Mongolian empire personified by Genghis Khan. During the time of this empire, the fermented mare milk was the drink to honor and thank warriors and leading persons, it was not meant for everybody. Although it eventually became a drink for normal people, it has kept its honorable meaning. Like many other traditions, this one feels the influence of globalization. Other products, like industrial yogurt, coming mainly from China and western countries, have tended to replace it more and more, mainly in urban areas. However, in rural and poorer regions it is still of great importance.

Biochemistry

Homofermentative process

Homofermentative bacteria convert glucose to two molecules of lactate and use this reaction to perform substrate-level phosphorylation to make two molecules of ATP:

glucose + 2 ADP + 2 P_i → 2 lactate + 2 ATP

Heterofermentative process

Heterofermentative bacteria produce less lactate and less ATP, but produce several other end products:

glucose + ADP + P_i → lactate + ethanol + CO₂ + ATP

Examples include Leuconostoc mesenteroides, Lactobacillus bifermentous, and Leuconostoc lactis.

Bifidum pathway

Bifidobacterium bifidum utilizes a lactic acid fermentation pathway that produces more ATP than either homolactic fermentation or heterolactic fermentation:

2 glucose + 5 ADP + 5 P_i → 3 acetate + 2 lactate + 5 ATP

Major genera of lactose-fermenting bacteria

Main article: Lactic acid bacteria

Some major bacterial strains identified as being able to ferment lactose are in the genera Escherichia, Citrobacter, Enterobacter and Klebsiella . All four of these groups fall underneath the family of Enterobacteriaceae. These four genera are able to be separated from each other by using biochemical testing, and simple biological tests are readily available. Apart from whole-sequence genomics, common tests include H2S production, motility and citrate use, indole, methyl red and Voges-Proskauer tests.

Applications

Lactic acid fermentation is used in many areas of the world to produce foods that cannot be produced through other methods. The most commercially important genus of lactic acid-fermenting bacteria is Lactobacillus, though other bacteria and even yeast are sometimes used. Two of the most common applications of lactic acid fermentation are in the production of yogurt and sauerkraut.

Fermented fish

Main article: Fermented fish

In some Asian cuisines, fish is traditionally fermented with rice to produce lactic acid that preserves the fish. Examples of these dishes include burong isda of the Philippines; narezushi of Japan; and pla ra of Thailand. The same process is also used for shrimp in the Philippines in the dish known as balao-balao.

Kimchi

Main article: Kimchi

Kimchi also uses lactic acid fermentation.

Sauerkraut

Main article: Sauerkraut

Lactic acid fermentation is also used in the production of sauerkraut. The main type of bacteria used in the production of sauerkraut is of the genus Leuconostoc.

As in yoghurt, when the acidity rises due to lactic acid-fermenting organisms, many other pathogenic microorganisms are killed. The bacteria produce lactic acid, as well as simple alcohols and other hydrocarbons. These may then combine to form esters, contributing to the unique flavor of sauerkraut.

Sour beer

Main articles: Lambic and Berliner Weisse

Lactic acid is a component in the production of sour beers, including Lambics and Berliner Weisses.

Yogurt

Main article: Yogurt

The main method of producing yogurt is through the lactic acid fermentation of milk with harmless bacteria. The primary bacteria used are typically Lactobacillus bulgaricus and Streptococcus thermophilus, and United States as well as European law requires all yogurts to contain these two cultures (though others may be added as probiotic cultures). These bacteria produce lactic acid in the milk culture, decreasing its pH and causing it to congeal. The bacteria also produce compounds that give yogurt its distinctive flavor. An additional effect of the lowered pH is the incompatibility of the acidic environment with many other types of harmful bacteria.

For a probiotic yogurt, additional types of bacteria such as Lactobacillus acidophilus are also added to the culture.

In vegetables

Main article: Silage

Lactic acid bacteria (LAB) already exists as part of the natural flora in most vegetables. Lettuce and cabbage were examined to determine the types of lactic acid bacteria that exist in the leaves. Different types of LAB will produce different types of silage fermentation, which is the fermentation of the leafy foliage. Silage fermentation is an anaerobic reaction that reduces sugars to fermentation byproducts like lactic acid.

Physiological

Lactobacillus fermentation and accompanying production of acid provides a protective vaginal microbiome that protects against the proliferation of pathogenic organisms.

Lactic acid fermentation and muscle cramps

Main article: Muscle contraction

During the 1990s, the lactic acid hypothesis was created to explain why people experienced burning or muscle cramps that occurred during and after intense exercise. A lack of oxygen inside of the muscle cells resulted in lactic acid fermentation. This is due to the cell needing oxygen as a terminal electron acceptor to produce ATP. Without oxygen present, the cells needed to create energy through a different method. Lactic acid, or lactate and H+ were created as a byproduct. This buildup of lactic acid causes a burning sensation inside of the muscle cells, causing leg cramps and discomfort.

Research from 2006 has suggested that acidosis isn't the main cause of muscle cramps, but instead is due to a lack of potassium inside the muscles, leading to contractions of the muscles under high stress. Another change to the lactic acid hypothesis is that when sodium lactate is inside of the body, there is a higher period of exhaustion in the host after a period of exercise.

Lactic acid fermentation is important to muscle cell physiology. When muscle cells are undergoing intense activity, like sprinting, they need energy quickly. There is only enough ATP stored in muscles cells to last a few seconds of sprinting. The cells then default to fermenting lactic acid, since they are in an anaerobic environment. Through lactic acid fermentation, muscle cells are able to produce ATP and NAD+ to continue glycolysis, even under strenuous activity.

The vaginal environment is heavily influenced by lactic acid producing bacteria. Lactobacilli spp. that live in the vaginal canal assist in pH control. If the pH in the vagina becomes too basic, more lactic acid will be produced to lower the pH back to a more acidic level. Lactic acid producing bacteria also act as a protective barrier against possible pathogens such as bacterial vaginosis and vaginitis species, different fungi, and protozoa through the production of hydrogen peroxide, and antibacterial compounds. It is unclear if further use of lactic acid, through fermentation, in the vaginal canal is present.

Benefits for the lactose intolerant

Main article: Lactose intolerance

In small amounts, lactic acid is good for the human body by providing energy and substrates while it moves through the cycle. In lactose intolerant people, the fermentation of lactose to lactic acid has been shown in small studies to help lactose intolerant people. The process of fermentation limits the amount of lactose available. With the amount of lactose lowered, there is less build up inside of the body, reducing bloating. Success of lactic fermentation was most evident in yogurt cultures. Further studies are being conducted on other milk produces like acidophilous milk.
