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. ^ 3 cl, 1 ex |
