FIELD: chemistry.
SUBSTANCE: group of inventions relates to the putrescine producing microorganism, and to the use of said microorganism putrescine production method. In the proposed microorganism, the protein activity is increased having the amino acid sequence, as presented in the SEQ ID NO: 21 or 23, compared to the said protein activity in the wild-type microorganism. Putrescine production method includes the said microorganism culturing with the cells culture production, and the putrescine isolation from the cultured microorganism or cells culture.
EFFECT: group of inventions provides putrescine production in high yield.
