Lactic Acid Bacteria

Many persons atomic number 18 oblivious to the fact that when they implement certain pleasing viands products like yogurt, buttermilk or cheese, they be actually take get laid bacterial biomass which has stiflingified the milk essence and contains a mixed mantrap of bacterial slime layers. perhaps it is a blessing that adjacent people be unconscious(predicate) beca economic consumption when most hear the musing ?bacteria,? their first thought is of a smallscopic unicellular macrocosm that causes various types of diseases especially if it is lay down in food. This may be true for most micro organisms, but there ar some bacterial species that are essential in the execute of those tasty foods, (Johnson-Green, 2002). One such(prenominal) group of bacteria is the lactic Acid Bacteria (LAB). Kun (2003) has embed that it has become increasingly hard to define this set of organisms as most opinions differ as to which organisms should be a spell of this group. However, they contribute be generally defined as a large group of pertain bacteria that have analogous properties and convert carbohydrates to lactic caustic by lactic window glass fermentation. They are heterotrophic and heap be found extensively in nature including yap leaves (e.g. Lactobacillus, Leuconostoc), the animal?s oral cavity (e.g. Streptococcus mutans), digestive system (e.g. Enterococcus faecalis), genitourinary parcel (e.g. Lactobacillus) as well as faecal matter, compost and moulder vegetation.

These areas normally have an adapt supply of amino acids and vitamins (Murray et al, 1998; lucre 1). They are aero tolerant anaerobes which peeved they green goddess tolerate type O but do non use it, (Johnson- Green, 2002). The group consist of a number of grand positive(p) bacteria which include 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 tot of lactic acid produced... If you penury to get a entire essay, order it on our website: Ordercustompaper.com
