Title:

PROCESS FOR PRODUCING TARGET SUBSTANCE BY FERMENTATION METHOD

Document Type and Number:

WIPO Patent Application WO/2001/005979

Kind Code:

A1

Abstract:

A process for producing a target substance by using a microorganism which comprises culturing the microorganism in a medium, producing and accumulating the target substance in the medium, and then collecting the target substance, wherein use is made of a microorganism capable of producing the target substance and having an enhanced RNA polymerase activity as the microorganism to thereby improve the productivity of the target substance.
