Abstract
The present invention relates to microbial variants producing homo-succinic acid at high yields and a method for producing homo-succinic acid using the same, more particularly, to a microbial variant constructed by disrupting a lactate dehydro-genase-encoding gene (idhA) and an acetate kinase-encoding gene (ackA), as well as a method for producing homo-succinic acid at high concentration, which comprises culturing such variants using glucose as a carbon source in anaerobic conditions.
