FIELD: biotechnology.
SUBSTANCE: method is proposed for producing a nutrient substrate for growing the STI-1 strain of the anthrax microbe, including dehydration on a spray-type drying unit of a liquid nutrient substrate containing enzymatic casein hydrolysate and a solution of processed corn extract in a ratio of 70% and 30%, at a feed rate of 20 to 25 dm3·h-1, an air temperature at the inlet from 118 to 122ºC and at the outlet from 85 to 90ºC.
EFFECT: method provides a technologically advanced nutrient substrate with an extended service life in the production of anthrax vaccine.
