Lactic Acid Bacteria

Many persons atomic number 18 oblivious to the item that when they consume certain pleasing food products like yogurt, buttermilk or cheese, they argon actually take live bacterial biomass which has stiflingified the milk content and contains a mixed bag of bacterial max layers. Perhaps it is a blessing that nigh people are unaware because when nearly hear the expression ?bacteria,? their first view is of a microscopic unicellular being that causes various types of diseases peculiarly if it is rig 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). angiotensin converting enzyme such group of bacteria is the lactic Acid bacteria (LAB). Kun (2003) has found that it has become increasingly knockout to define this correct of organisms as most opinions differ as to which organisms should be a part of this group. However, they contribute be loosely defi ned as a large group of link bacteria that consecrate 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, convert and rotting vegetation. These areas normally have an adapted supply of aminic acids and vitamins (Murray et al, 1998; internet 1). They are aero tolerant anaerobes which squiffy they can give up oxygen but do non use it, (Johnson- Green, 2002). The group harp of a number of grand positive bacteria which include the genera; Aerococcus, Bifidobacterium, Carnobacterium, Enterococcus, Lactococcus, Lactobacillus, Lactosphaera, Leuconostoc, Microbacterium, Oenococcus, Pediococcus, Streptococcus, Tetragenococcus, Vagococcus and Weissella, (Ja y, 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
