Title:
METHOD FOR CULTURING MICROORGANISM AND METHOD FOR PRODUCING ORGANIC COMPOUND
Document Type and Number:
WIPO Patent Application WO/2017/169275
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a method for culturing a microorganism, whereby the microorganism can adapt to an inhibitor and thus fermentation inhibition can be sufficiently decreased, and a method for producing an organic compound wherein the microorganism obtained above or a processed product thereof is used. A method for culturing a microorganism in a liquid culture medium containing a saccharide, wherein, in the liquid culture medium, the carbonyl value based on compound(s) other than the saccharide is 100 μmol eq or greater per gram of the liquid culture medium. A method for producing an organic compound wherein the aforesaid microorganism or a processed product thereof is used.
