  • ETHANE-1,2-DIOL PRODUCING MICROORGANISM AND A METHOD FOR PRODUCING ETHANE-1,2-DIOL FROM D-XYLOSE USING THE SAME
    Publication number: 20150147794
    Abstract: Disclosed herein is a microorganism capable of producing ethane-1,2-diol from D-xylose, and a method for producing ethane-1,2-diol using the same. More specifically, the present invention relates to an engineered Escherichia coli (E. coli) prepared by knocking out a D-xylose isomerase gene and/or an aldehyde dehydrogenase gene within the genomic DNA of E. coli and transforming an expression vector including a D-xylose dehydrogenase gene into the E. coli, and an efficient method for producing ethane-1,2-diol from D-xylose using the engineered E. coli.

  • Recombinant producing D-xylonic acid from D-xylose and method for producing D-xylonic acid using the same
    Patent number: 8637279
    Abstract: Disclosed herein is a recombinant Escherichia coli (E. coli) capable of producing D-xylonic acid from D-xylose and a method for producing D-xylonic acid using the same. The recombinant E. coli producing D-xylonic acid from D-xylose according to the present invention is a recombinant E. coli EWX4 (Microorganism deposition number KCTC11988BP) capable of producing D-xylonic acid from D-xylose. When utilizing the recombinant E. coli prepared by the method of the present invention, it is possible to produce D-xylonic acid from D-xylose with high yield while reducing production cost using sole carbon source.
