Bacteriocin production: a probiotic trait?
Bacteriocins are an abundant and diverse group of ribosomally synthesized antimicrobial peptides produced by bacteria and archaea. Traditionally, bacteriocin production has been considered an important trait in the selection of probiotic strains, but until recently, few studies have definitively demonstrated the impact of bacteriocin production on the ability of a strain to compete within compl...
متن کاملBacteriocin Production and Susceptibility Among Strains
Whereas the bacteriocin activity of eight strains of Streptococcus mutans was unaffected by growth in the presence of sucrose, such a medium rendered five S. mutans and one S. salivarius indicator strains unsusceptible to the bacteriocins. In contrast, the susceptibility of three S. faecalis and one S. pyogenes strains was unaltered when these indicators were grown in the presence of sucrose. S...
متن کاملNew method for detecting bacteriocin production.
Bacteriocin production can be easily detected by using both sides of the agar contained in a standard petri dish.
متن کاملBacteriocin production: a relatively unharnessed probiotic trait?
Probiotics are "live microorganisms which, when consumed in adequate amounts, confer a health benefit to the host". A number of attributes are highly sought after among these microorganisms, including immunomodulation, epithelial barrier maintenance, competitive exclusion, production of short-chain fatty acids, and bile salt metabolism. Bacteriocin production is also generally regarded as a pro...
متن کاملYersinia intermedia: temperature-dependent bacteriocin production.
Yersinia enterocolitica and related Yersinia species share many temperature-dependent biological attributes. The present report documents temperature-dependent production of a bacteriocin-like substance only among Yersinia strains which ferment L-rhamnose, raffinose, and melibiose and which have been tentatively designed Y. intermedia. When tested by the "lawn-spotting" technique at 25 and 37 d...
