FIELD: medicine.
SUBSTANCE: microorganisms were obtained by destruction of SpeE gene, and, at least, one gene, taken from SpeG, ArgI or PuuP in microorganism, which has metabolic way of putrescine synthesis. In addition, claimed is method of said microorganisms obtaining and method of putrescine production by their culturing. Claimed mutant microorganisms can be applied for large-scale production of putrescine for industrial application.
EFFECT: possibility of microorganisms to increased putrescine production.
