Fecha de publicación: -- Fuente: WIPO "milk" A method for preparing a bacterial preparation of direct bringing in for solid rennet cheeses with a low temperature of the second heating provides for preparation of a vivifying medium based on hydrolysate milk with an addition of corn extract, trisubstituted natrium citrate and manganese sulphate, bringing in inoculum containing mesophilic lactate bacteria Lactococcus lactis ssp. diacetilactis and Lactococcus lactis ssp. cremoris, cultivation of bacterial composition, separation of a biomass, mixing it with a protective medium, freezing and drying. To the composition of the bacterial preparation from mesophilic lactate bacteria the following strains brought in, which are specially selected by a level of acid forming, ability to proteolysis and accumulation of aromatic substances, by antagonistic activity and stability to bacteiophages are: Lactococcus lactis ssp. diacetilactis IMB В-7061, Lactococcus lactis ssp. diacetilactis IMB B-7062, Lactococcus lactis ssp. cremoris IMB B-7064 and Lactococcus lactis ssp. lactis IMB B-7063, and also a strain of Lactobacillus Lactobacillium casei ssp. casei IMB B-7017 in a ratio 0.5:0.5:0.5:0.5:0.3 respectively of every strain.
