PROCESS FOR PRODUCTION OF ORGANIC ACID

摘要

An organic acid can be produced by: allowing a bacterium or a processed product thereof to act on an organic raw material in a reaction solution containing a carbonate ion, a bicarbonate ion or a carbon dioxide gas, thereby producing the organic acid; and collecting the organic acid, wherein the bacterium is so modified as to have an enhanced phosphoenolpyruvic acid carboxykinase activity, is capable of producing the organic acid, belongs to the family Enterobacteriaceae, and belongs to the genus selected from the genera Enterobacter, Pantoea, Erwinia, Klebsiella and Raoutella.
