BACTERIUM STRAIN LACTOCOCCUS LACTIS SUBCPECIES LACTIS B-8558 USEFUL IN DAIRY PRODUCT PREPARATION AND METHOD FOR PRODUCTION OF STARTER CULTURE OF STRAIN LACTOCOCCUS LACTIS SUBCPECIES LACTIS B-8558
BACTERIUM STRAIN LACTOCOCCUS LACTIS SUBCPECIES LACTIS B-8558 USEFUL IN DAIRY PRODUCT PREPARATION AND METHOD FOR PRODUCTION OF STARTER CULTURE OF STRAIN LACTOCOCCUS LACTIS SUBCPECIES LACTIS B-8558
FIELD: biotechnology, in particular dairy industry with high rheologic and quality characteristics.;SUBSTANCE: invention relates to new natural strain of lactic acid bacteria capable of exopolysaccharide synthesis in amount sufficient to improve rheologic product characteristics without introducing of food supplement and to increase functional properties of products producing with said strain. Starter culture of claimed strain is produced by fermentation under condition of semi-continuous deep culturing on broth containing milky whey, concentrated hydrolyzed milk, KH2PO4, Na2HPO4, MgSO4, sodium citrate, and distilled water. Fermentation is carried out at 22-32°C, constant pH 6.0-7.0 up to accumulation of living cell amount of 8.4-9.5 lg CFU/cm3. Biomass is separated, resuspended in protective medium, wherein as cryoprotector defatted milk with increased mass part of dry matter (up to 15 %) or defatted milk blended with gelatin in equal ratio is used; frozen and lyophilized. After drying biomass in bottles is sealed or pre-packed in sealed packing materials.;EFFECT: starter culture with maximal activity; products with improved quality and prolonged storage time.;2 cl, 2 dwg, 3 ex
