anti-microbial effects of the lactic acid bacteria have been studied and proved in various investigations. this investigation aimed to study the anti-yeast effect of two isolated lactic acid bacteria species from “chal” (a product from yogurt) as biological preservatives in doogh. to do so, anti-yeast activity of l. brevis and e. faecium against saccharomyces cerevisiae, kluyveromyces. marxianu...

Rhodotorula glutinis as an antagonism show good biocontrol performance against various post-harvest diseases in fruits. In the present study, strong attachment capability of R. glutinis to spores and hyphae of Botrytis cinerea was observed. Further analysis showed that certain protein components on the yeast cell surface played critical role during the interaction between R. glutinis and B. cin...

Background: Lactic Acid Bacteria are a group of Gram-positive bacteria which are widely used in the food industry as organic ferments called starter cultures. In this study, Enterococcus faecium, Leuconostoc mesenteroides, Lactococcus lactis, Weissella paramesenteroides, and Lactiplantibacillus plantarum isolated from Moroccan table olives were tested for their acquisition of probiotic and tech...

Four Enterococcus faecium strains isolated from fermented products were evaluated for potential use as probiotic strains. In addition to efaAfm gene, commonly found in E. faecium food isolates, none of the isolates possessed virulence genes and none had positive reactions for the production of tyramine, histamine, putrescine and cadaverine in the screening medium used. All of these four isolate...

1 2 A Central Composite Face design was used to study growth and tyramine production 3 by two strains of lactic acid bacteria, Lactobacillus brevis CECT 4669 and Enterococcus 4 faecium BIFI-58. The effects of five physicochemical factors (incubation temperature and 5 time, environmental pH, added tyrosine concentration, and pyridoxal-5-phosphate (PLP) 6 supplementation) on cell growth and tyram...

considering the emergence of antibiotic resistance, scientists are interested in using new antimicrobial agents in the treatment of infectious diseases including infections of the enteric systems. lactic acid bacteria have the great potential to produce antimicrobial compounds that inhibit and control pathogenic bacteria. the aim of this study was to determine the anti-bacterial and anti-adhere...

The present study compared the antagonistic activity and probiotic properties of two Lactic Acid Bacteria (LAB) such as Enterococcus faecium NCIM 2605 and Lactococcus lactis NCIM 2606. Bacteriocin from both the cultures was produced using MRS broth by shake flask fermentation. In well diffusion method, the cell free supernatant (CFS) of E. faecium showed activity against both gram positive and ...

Background: Enterococci have emerged as a major cause of nosocomial infections and within this group, Enterococcus faecalis and Enterococcus faecium cause the majority of human and livestock enterococcal infections. In this article, we tried to determine antibiotics and metals resistance patterns of E. faecalis and E. faecium strains. Methods: One hundred sixty different strains of E. faecalis...
