Abstract
A bacteriocin, Fermentcin B produced by Lactobacillus fermentum, was i dentified from the inhibitory products of twenty-nine mesophilic lacti c acid bacteria. It has a bactericidal activity with a narrow inhibito ry spectrum. The bacteriocin is heat stable at 100 degrees C for 30 mi n and stable in pH range of 3.0 to 8.0. Fermentcin B lost its activity after treatment with alpha-chymotrypsin, proteinase-K, and amylogluco sidase.
