Lactic Acid Bacteria

Many persons atomic number 18 oblivious to the point that when they consume certain pleasing food products like yogurt, butter take out or cheese, they atomic number 18 actually take live bacterial biomass which has stiflingified the milk content and contains a mixed bag of bacterial gook layers. Perhaps it is a blessing that nigh people are unaware because when almost hear the expression ?bacteria,? their first approximation is of a microscopic unicellular being that causes various types of diseases curiously if it is order in food. This may be true for most micro organisms, but there are some bacterial species that are essential in the fabricate of those tasty foods, (Johnson-Green, 2002). mavin such group of bacteria is the lactic Acid bacterium (LAB). Kun (2003) has found that it has become increasingly knockout to define this localize of organisms as most opinions differ as to which organisms should be a part of this group. However, they contribute be loo sely defined as a large group of link bacteria that consider similar properties and convert carbohydrates to lactic acidulated by lactic acid fermentation. They are heterotrophic and can be found extensively in nature including fix leaves (e.g. Lactobacillus, Leuconostoc), the animal?s oral cavity (e.g. Streptococcus mutans), digestive system (e.g. Enterococcus faecalis), GU tract (e.g. Lactobacillus) as well as faecal matter, convert and rotting vegetation.

These areas normally have an adapted supply of amino group acids and vitamins (Murray et al, 1998; internet 1). They are aero tolerant anaerobes which sq uiffy they can put forward oxygen but do n! on use it, (Johnson- Green, 2002). The group populate of a number of grand positive bacteria which involve the genera; Aerococcus, Bifidobacterium, Carnobacterium, Enterococcus, Lactococcus, Lactobacillus, Lactosphaera, Leuconostoc, Microbacterium, Oenococcus, Pediococcus, Streptococcus, Tetragenococcus, Vagococcus and Weissella, (Jay, 2000). They can be categorised into two groups based on the amount of lactic acid produced... If you want to get a full essay, order it on our website: OrderCustomPaper.com
