Isolation and characterization of bacteriocins produced by lactic acid bacteria
This study presents the characterization of eight bacteriocins produced by lactic acid bacteria (LAB) previously isolated from a traditional cheese, Pico cheese. All isolates were active against Listeria monocytogenes and only three against Clostridium perfringens. Bioactivity was studied after treatment with different enzymes, organic solvents, surfactants, temperature, pH and NaCl. The antimi...
متن کاملExopolysaccharides produced by lactic acid bacteria of kefir grains.
A Lactobacillus delbrueckii subsp. bulgaricus HP1 strain with high exopolysaccharide activity was selected from among 40 strains of lactic acid bacteria, isolated from kefir grains. By associating the Lactobacillus delbrueckii subsp. bulgaricus HP1 strain with Streptococcus thermophilus T15, Lactococcus lactis subsp. lactis C15, Lactobacillus helveticus MP12, and Sacharomyces cerevisiae A13, a ...

متن کاملAntimicrobial 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 کاملLactic Acid Bacteria
Lactic acid bacteria comprise an ecologically diverse group of microorganisms united by formation of lactic acid as the primary metabolite of sugar metabolism (Davis et al., 1985b; 1988; Lonvaud-Funel, 1999; Carr et al., 2002; Liu, 2002). These bacteria utilize sugars by either homoor heterofermentative pathways (Section 2.4.1) as well as l-malic acid, a major acid present in grape must (Sectio...
