Rapid Isolation and Purification of Secreted Bacteriocins from Streptococcus mutans and Other Lactic Acid Bacteria
Authors:  Marcus Cheng, Siew-Ging Gong and Céline M. Lévesque, date: 11/20/2020, view: 600, Q&A: 0
Bacteriocins are small ribosomally synthesized antimicrobial peptides produced by some microorganisms including lactic acid bacteria (LAB), a group of Gram-positive bacteria (cocci, rods) expressing high tolerance for low pH. Bacteriocins kill ...
