  • Homo-succinic acid producing microorganism variant and process for preparing succinic acid using the same
    Patent number: 8877482
    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.
    Type: Grant

  • RECOMBINANT MICROORGANISM HAVING AN ABILITY OF USING SUCROSE AS A CARBON SOURCE
    Publication number: 20110269183
    Abstract: The present invention relates to a recombinant microorganism capable of metabolizing sucrose, and more particularly to a recombinant microorganism capable of metabolizing sucrose in which a gene encoding sucrose phosphotransferase and/or a gene encoding sucrose-6-phosphate hydrolase is introduced or to a recombinant microorganism capable of metabolizing sucrose in which a gene encoding ?-fructofuranosidase is introduced. According to the present invention, a recombinant microorganism capable of using inexpensive sucrose as a carbon source instead of expensive glucose is provided. In addition, in a process of culturing microorganisms which have been incapable of using sucrose as a carbon source, sucrose can substitute for other carbon sources including glucose.
