FIELD: chemistry.
SUBSTANCE: invention relates to biotechnology and provides a microorganism having ornithine-producing capacity, where activity of ornithine carbamoyltransferase and a protein participating in glutamate (NCgl1221) export are modified such that they are deleted compared to their endogenous activity. The invention also relates to a method of producing ornithine using said microorganism.
EFFECT: invention enables to obtain L-ornithine with high efficiency.
