FIELD: biotechnology, medicinal microbiology.
SUBSTANCE: invention relates, in particular, to a method for preparing nutrient medium used for production of bacteriophages. Nutrient medium for production of bacteriophages contains acidic casein hydrolyzate as a base with hydrolysis degree 0.6-0.7 and vitamins: nicotinic acid, folic acid, calcium pantothenate, riboflavin, thiamine bromide and biotin, and distilled water. Also, invention relates to a method for preparing nutrient medium used for production of bacteriophages involving hydrolysis of natural casein mixed with water using hydrochloric acid under pressure 0.2 ± 0.05 MPa up to attainment of hydrolysis degree 0.6-0.7 being isoprecipitation and treatment with carbon are carried out simultaneously. Invention provide enhancing growth properties of medium and quality of bacteriophages produced and reducing the cost.
EFFECT: improved preparing method.
