FIELD: biotechnology.
SUBSTANCE: invention relates to biotechnology and represents modified microorganism of Corynebacterium genus with increased ability to produce putrescine, where protein activity having amino acid sequence presented in SEQ ID NO: 18 or SEQ ID NO: 20, in microorganism of Corynebacterium genus, capable of producing putrescine, attenuated or eliminated as compared to its endogenous activity. Invention also relates to putrescine producing method, including cultivation of said modified microorganism of Corynebacterium genus and separating putrescine from obtained cell culture.
EFFECT: invention allows to produce putrescine with high output.
