Lactobacillus isolate in yogurt inhibits multidrug-resistant, gram-negative bacteria.

Lactobacillus isolate in yogurt inhibits multidrug-resistant, gram-negative bacteria. A Lactobacillus isolate found in commercial yogurt inhibited the growth of several multidrug-resistant, gram-negative bacteria, according to a study. Researchers from the department of biology at Howard University in Washington, D.C., said they discovered a potentially novel L. parafarraginis strain while testing lactic acid bacteria (LAB) isolates from commercial yogurt and cheese. Researchers said a Lactobacillus isolate found in commercial yogurt inhibited the growth of several multidrug-resistant, gram-negative bacteria. Their analysis indicated that the inhibitory agent was a bacteriocin — peptides created by bacteria that are active against related bacteria. Bacteriocins have importance primarily in the food industry.more
