  • Pta LDHA double mutant Escherichia coli SS373 and the method of producing succinic acid therefrom
    Patent number: 6448061
    Abstract: This invention relates to a mutant Escherichia coli SS373 and the production of succinic acid by using the above strain. In detail, a novel E. coli SS373 (W3110 pta::Tn10 ldhA::Km) with the deficiency in the acetate and lactate forming pathways was constructed by genetic engineering technique. An aerobically grown SS373 was then cultured by means of the anaerobic condition shift during the succinate producing stage, which resulted in the efficient production of succinic acid with a higher yield.
