Influence of redox processes on the antioxidant activity of the symbiotic starter biomass

The biological system of the microbial antioxidant protection is a subject certain level physiological oxidative process. To prevent oxidation, regulator intracellular metabolism, tripeptide glutathione, accumulated in cells. Glutathione very important for response and maintenance redox potential. Its role several metabolic adaptive symbiotic processes yeasts lactic acid bacteria not completely elucidated scientific practical interest. Glycine component polypeptide chain substances that form primary structure glutathione. aim this study was to determine an effect on activity through regulation glutathione constituent, glycine, nutrient medium obtain biomass multicomponent starter culture. As result performed investigations, direct dependence between calculated by coulometric method concentration glycine introduced into determined. It has been established addition 0.2–0.8% leads decrease results reflected publication show process development aerobic microorganisms presence reducing occurs quite actively. number increased from 1.6· 10 4 3.6· 5 CFU/g during 24-hour incubation. An increase 0.5 0.8% enhanced both anaerobic microorganisms. found 1.5% shifted toward metabolism; amount reduced culture liquid practically twofold, while oxidized test sample range 0 5%. This allows regarding as potential yeasts.
