Lactic Acid Bacteria and Bifidobacteria

Lactic acid bacteria (LAB) and bifidobacteria are amongst the most important groups of microorganisms used in the food industry. For example, LAB are used in the production of fermented products, such as yoghurts, cheese and pickled vegetables. In addition LAB can inhibit the growth of spoilage microbes and/or pathogens in their environment by lowering the pH and/or through the production of antimicrobial peptides, called bacteriocins.
