PROCESS OF NUTRIENT MEDIUM PRODUCTION Russian patent published in 2008 - IPC C12N1/20 

FIELD: chemistry, organic, production of sour milk products.

SUBSTANCE: lactoserum containing 10% of dry substances will be pasteurised at 90°C during 20 min, cooled to 45°C, reduced with ammonia solution to pH 7.0. Then the Streptococcus thermophilus barm will be introduced and the mixture will be ripened at 40°C during 5 hours, additive will be introduced in the form of milk protein hydrolysate, the mixture will be mixed and sterilised, cooled to 38°C and reduced with ammonia solution to pH 6.8. The nutrient medium thus obtained will enable one to shorten the process of cultivating bifido- and lactobacteria to 24 hours and to increase their concentration when obtaining liquid bacterial concentrate.
