| Abstract: | A new composition of the nutrient medium for cultivation of the tetracycline-producing organism was developed with the fermentative hydrolysate of the tetracycline production mycelial waste as a source of nitrogen: 0.02 to 0.04 g/l by amino nitrogen. The use of the medium made it possible to increase the tetracycline yield by 5 to 25 per cent, to exclude cornsteep liquor from the medium composition, to provide a more efficient recovery of the waste and to significantly decrease the environment pollution. |
