ABSTRACT
Lactic acid bacteria constitute a large group of non sporulating, Gram positive catalase and oxidize negative rods and cocci that produce lactic acid as the major metabolite of the carbohydrate fermentation. LAB are aerotolerant anaerobe and generally have complex nutritional requirements especially for amino acids and vitamins. The genera that comprise the LAB are at its core Lactobacillus, Lactococcus, Leuconostoc, Pediococcus, Streptococcus as well as the more peripheral Aerococcus, Carnobacterium, Enterococcus, Oenococcus, Sporolactobacillus, Tetragenococcus, Vagococcus, Weissella and Bifi dobacterium genus.
