Method for producing N-acetyl-D-glucosamine and/or D-glucosamine hydrochloride by microbial fermentation

摘要

A method for producing N-acetyl-D-glucosamine and/or D-glucosamine hydrochloride by means of microbial fermentation. By expressing a vitreoscilla hemoglobin in a microorganism, N-acetyl-D-glucosamine and/or D-glucosamine hydrochloride are produced with higher efficiency and higher yield.
