METHOD FOR PRODUCING HEPAROSAN AND BACTERIUM OF GENUS ESCHERICHIA HAVING HEPAROSAN-PRODUCING ABILITY

摘要

An object of the present invention is to provide a method for efficiently producing heparosan by improving a heparosan-producing ability through genetic modification of a bacterium of the genus Escherichia which has a heparosan-producing ability. The present invention relates to a bacterium of the genus Escherichia which has a genetic modification that increases an expression of a kpsS gene, and which has a heparosan-producing ability; and a method for producing heparosan using the bacterium.
