  • Patent number: 11459574
    Abstract: Provided is a method for improving productivity in producing an organic compound in a bacterium that originally does not have an inherent ED pathway. In one aspect, provided is a transformant of a coryneform bacterium that is obtained by introducing the Entner-Doudoroff pathway into the coryneform bacterium as a host. In another aspect, provided is a transformant of a coryneform bacterium that is obtained by introducing, into a coryneform bacterium as a host a gene in which an enzyme having glucose-6-phosphate dehydrogenase activity is encoded, a gene in which an enzyme having 6-phosphogluconate dehydratase activity is encoded, and a gene in which an enzyme having 2-keto-3-deoxy-6-phosphogluconate aldolase activity is encoded.
