Two hunderd five strains of Proteus rettgeri from epidemic and nonepidemic sources were differentiated by a new biotyping scheme, agglutination in O antisera, antimicrobial resistance patterns, and a new scheme based on bacteriocin production. The P. rettgeri were divided into 10 groups by their fermentation of lactose, sucrose, D-mannitol, and salicin. These groups were then subdivided into 19...

A collection of propionibacteria was screened for bacteriocin production. A new bacteriocin named propionicin T1 was isolated from two strains of Propionibacterium thoenii. This bacteriocin shows no sequence similarity to other bacteriocins. Propionicin T1 was active against all strains of Propionibacterium acidipropionici, Propionibacterium thoenii, and Propionibacterium jensenii tested and al...

The bacteriocin produced by Lactococcus lactis IFPL105 is bactericidal against several Lactococcus and Lactobacillus strains. Addition of the bacteriocin to exponential-growth-phase cells resulted in all cases in bacteriolysis. The bacteriolytic response of the strains was not related to differences in sensitivity to the bacteriocin and was strongly reduced in the presence of autolysin inhibito...

Background: Aquaculture is one amongst the growing and major food producing sectors. Shrimp culture is one of the subsectors of aquaculture that attracts more attention because of the economic interest. However, the shrimp culture systems have been facing severe consequences and economical losses due to disease outbreaks. Risk of disease outbreak can be combated with the application of probioti...

About 300 bacterial strains (belonging to different genera) were isolated from different indigenous ecological niches. The sources include food (milk and yogurt), water (drinking water and waste water), soil (garden), stool (healthy infants) and clinical samples. The isolates were screened for their bacteriocin production where 54.3% were found as bacteriocin producers. Among them, Lactobacilli...

Background and Objectives Human milk is a continuous supply of Lactic Acid bacteria (LAB), including enterococci with probiotic potentials. The aim of this study was to analyze two Enterococcus species, isolated from human milk for their probiotic potential, bacteriocin producing ability and virulence traits. Materials and Methods Enterococcus faecium TA0033 and E. faecalis TA102 were tested ...

conclusions this study revealed the presence of bacteriocin-producing bacteria and probiotic bacteria in camel milk from the golestan province of iran. results a total of 64 isolates were analyzed based on biochemical tests and morphological characteristics. the most frequently isolated lab was enterococci. weissella, leuconostoc, lactobacilli and pediococci were less frequently found. based on...

SIMOVA, E. D., D. M. BESHKOVA, Z. P. DIMITROV and Z. I. SIMOV, 2008. In vitro and in situ Bacteriocin activity of lactic acid bacteria from Bulgarian dairy products and methods for making of Lactobacillus protective fermented milks with Bacteriocin inhibitory substances. Bulg. J. Agric. Sci., 14: 28-42 The studies are based on two theses: 1) Fermented milks are the shortest route and the most a...

Skalka, B.: Bacteriocin Typing of Staphylococci. Acta vet. Bmo, 61,1992: 179-187. The report describes bacteriocin typing of staphylococcal strains using the deferred method. The collection of active strains comprised 11 strains, Q of which were isolated by the author, namely 3 S. intermedius strains, 2 S. hominis strains and 1 strain each of S. epidermidis, S. simulans, S. sciuri and S. haemol...

background: weissellicin 110 is the only bacteriocin reported in weissella cibaria up to now. this bacteriocin represents several unique features. this is the first report on the gene sequence that encodes for the bacteriocin.objectives: providing a rapid detection method to isolate the weissellicin 110 encoding gene and determination of the bacteriocin distribution were the objectives.material...
