Bacteriocins from Lactic Acid Bacteria

Purification Techniques of Bacteriocins from Lactic Acid

The search for new antimicrobial peptides produced by lactic acid bacteria and other Gram-positive microorganisms has become an interesting field of research in the past decades The fact that bacteriocins are active against numerous foodborne and human pathogens are produced by generally regarded as safe (GRAS) microorganisms and are readily degraded by proteolytic host systems
