Bacteriocin production: a relatively unharnessed probiotic trait?
نویسندگان
چکیده
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 probiotic trait, but it can be argued that, in contrast to other traits, it is often considered a feature that is desirable, rather than a key probiotic trait. As such, the true potential of these antimicrobials has yet to be realised.

Impact of Environmental Factors on Bacteriocin Promoter Activity in Gut-Derived Lactobacillus salivarius.
Bacteriocin production is regarded as a desirable probiotic trait that aids in colonization and persistence in the gastrointestinal tract (GIT). Strains of Lactobacillus salivarius, a species associated with the GIT, are regarded as promising probiotic candidates and have a number of associated bacteriocins documented to date. These include multiple class IIb bacteriocins (salivaricin T, saliva...
متن کاملBacteriocin 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...

Boza is a low-pH and low-alcohol cereal-based beverage produced in the Balkan Peninsula. Barley was cooked and prepared according to a traditional recipe and inoculated with Enterococcus mundtii ST4V (a potential probiotic and bacteriocin-producing strain), commercially produced boza, Saccharomyces cerevisiae, and a combination of strain E. mundtii ST4V and Saccharomyces cerevisiae. Fermentatio...
متن کاملEffect of Bacteriocin Produced by Lactobacillus casei with Probiotic Potential Isolated from Milk on the Ability of Biofilm Production by Streptococcus salivarius Obtained from Dental Plaque
Background and purpose: Dental plaque is a biofilm that is formed on the surface of the tooth. Carious lesions are caused by inappropriate ecological changes in microbial flora of the plaque biofilm. In this study, the effect of Lactobacillus casei bacteriocin, isolated from dairy products, was investigated on Streptococcus salivarius biofilm formation. Materials and methods: In this experimen...

The present research was focused on probiotic characterization of lactic acid bacteria from fermented foods and beverage of Kinnaur and partial purification of bacteriocin. Lactic acid bacterial isolates were examined in-vitro for potential probiotic properties based on their low pH tolerance, bile-salt resistance, production of antimicrobial substances, exopolysaccharide production, proteolyti...
