Lactic Acid Bacteria

Lactic acid bacteria (LAB) are gram-positive usually non-motile non-spore-forming rods and cocci. These are gaining importance due to their generally recognized as safe status long-term use in food and beneficial probiotic properties. Genera that comprise the LAB are Lactobacillus Leuconostoc Pediococcus Lactococcus Streptococcus Enterococcus Tetragenococcus Carnobacterium and Weisella (Table 1). Besides their technological properties in food production LAB can confer beneficial properties to their hosts as probiotics. Beyond being probiotic certain strains of LAB are able to produce specific beneficial compounds in foods such as vitamins low calorie sweeteners antioxidants polysaccharides and minerals.
