ABSTRACT:
The present invention provides an aerobic coryneform bacterium transformant in which a lactate dehydrogenase gene is disrupted, and a pyruvate carboxylase gene is recombined so as to be highly expressed by a genetic engineering method. The aerobic coryneform bacterium transformant of the present invention can produce dicarboxylic acids from saccharides at a high production rate.
