Lactic Acid Bacteria

Many persons atomic number 18 oblivious to the detail that when they consume certain pleasing food products like yogurt, butter draw or cheese, they argon actually take live bacterial biomass which has stiflingified the milk content and contains a mixed bag of bacterial guck layers. Perhaps it is a blessing that nigh people are unaware because when virtually hear the expression ?bacteria,? their first public opinion is of a microscopic unicellular being that causes various types of diseases oddly if it is comprise 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). one such group of bacteria is the lactic Acid bacterium (LAB). Kun (2003) has found that it has become increasingly knockout to define this dress of organisms as most opinions differ as to which organisms should be a part of this group. However, they contribute be loosely defined as a large group of link bacteria that keep back 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), genitourinary tract (e.g. Lactobacillus) as well as faecal matter, compost and rotting vegetation.

These areas normally have an adapted supply of amino acids and vitamins (Murray et al, 1998; internet 1). They are aero tolerant anaerobes which squiffy they c an assume oxygen but do non use it, (Johns! on- Green, 2002). The group live of a number of grand positive bacteria which imply 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
