A MICROORGANISM OF CORYNEBACTERIUM GENUS PRODUCING N-ACETYL GLUCOSAMINE AND A METHOD OF PRODUCING N-ACETYL GLUCOSAMINE OR GLUCOSAMINE USING THE SAME

摘要

PURPOSE: A mutated Corynebacterium sp. microorganism producing N-acetyl glucosamine is provided to produce N-acetyl glucosamine and glucosamine. CONSTITUTION: A Corynebacterium sp. microorganism producing N-acetyl glucosamine has glucosamine-6-phosphate acetyltransferase activity and reduced glucosamine-6-phosphate diaminase activity. The glucosamine-6-phosphate acetyltrasferase is encoded by a sequence of sequence number 11. The glucosamine-6-phosphate acetyltransferase is expressed by induction or always. A method for producing N-acetyl glucosamine or glucosamine comprises: a step of culturing Corynebacterium sp, microoraganism having ability of producing N-acetyl glucosamine; and a step of collecting N-acetyl glucosamine or glucosamine.
