  • Patent number: 8735135
    Abstract: Disclosed is a means for improving the poor conversion efficiency in a conventional bioconversion system using a transformant which is given by introducing a gene originated from xerogenic organisms. A transformant is prepared by using a host which is defective in a gene encoding a multidrug efflux protein and introducing a gene originated from xerogenic organisms. Use of the transformant results in much effective microbial conversion of a hydrophobic or amphipathic substrate compound into a desired compound. In case, an Escherichia coli is used as the host, the gene encoding a multidrug efflux protein to be defective may be tolC, acrA, acrB and the like.

  • Patent number: 8460915
    Abstract: Disclosed is a means for improving the poor conversion efficiency in a bioconversion system using an Escherichia coli cell having a bacterium-originated cytochrome P-450 gene integrated therein. A recombinant Escherichia coli cell is produced by introducing aciB and aciC which encode a gene for the electron transport system originated from the Acinetobacter sp. OC4 strain into an Escherichia coli cell, and adding a polynucleotide encoding an N-terminal sequence composed of 48 amino acid residues of AciA and the like to the 5?-terminus of a bacterium-originated cytochrome P-450 gene, wherein AciA is an alkane-oxidative cytochrome P-450 originated from the Acinetobacter sp. OC4 strain. Use of the recombinant Escherichia coli cell results in much effective microbial conversion of a hydrophobic or amphipathic substrate compound into a desired compound.
