Antimicrobial Effect of Lactic Acid Bacteria against Common Pathogenic Bacteria
Abstract Background and Objective: Probiotics are living microorganisms that have beneficial effects on the health of digestive system. The aim of this study was to evaluate the antimicrobial ability of acidic and neutral supernatants (culture supernatant) of lactic acid bacteria against common bacterial pathogens. Meth...
متن کاملExopolysaccharides Production by Lactic Acid Bacteria
Exopolysaccharides (EPSs) are high molecular weight and biodegradable polymers. They are biosynthesized by a wide range of bacteria. Lactic acid bacteria (LAB) are also able to produce EPSs. EPSs can be classified into two groups. These are homopolysaccharides and heteropolysaccharides. Homopolysaccharides are polymers which are composed of one type of monosaccharide. Heteropolysaccharides are ...
متن کاملOptimization of β-galactosidase production from lactic acid bacteria
β-galactosidase, commonly known as lactase, represents commercially important enzyme that is prevalently used for lactose hydrolysis in milk and whey. To the date, it has been isolated from various sources. In this study different strains of lactic acid bacteria were assessed for their β-galactosidase productivity, and Lactobacillus acidophilus ATCC 4356 resulted with the highest production pot...
متن کاملAntimicrobial microbes-bacteriocin producing lactic acid bacteria
The contribution of lactic acid bacteria (LAB) to the improvement of food safety and stability of fermented foods has long been known. LAB overgrow other microorganisms of the same ecological niche in food products mainly due to lowering the pH, competing for nutrients, producing various antimicrobial substances such as organic acids, hydrogen peroxide, antibiotics and bacteriocins. Among these...
متن کاملPhenyllactic Acid: A Potential Antimicrobial Compound in Lactic acid Bacteria
3-Phenyllactic acid (PhLA) is a broad spectrum antimicrobial compound active against bacteria and fungi. PhLA exists in two chiral isomers, L-PhLA and D-PhLA which show antimicrobial activity. D-PhLA shows more antimicrobial activity than L-PhLA and hence it is receiving great attention as food and feed additive in place antibiotics which control the microbial contamination and thereby increase...
