Reduction of furfural to furfuryl alcohol by ethanologenic strains of bacteria and its effect on ethanol production from xylose.

abstract：:The Pichia stipitis xylose reductase gene (XYL1) was inserted into an autonomous plasmid that P. stipitis maintains in multicopy. The plasmid pXOR with the XYL1 insert or a control plasmid pJM6 without XYL1 was introduced into P. stipitis. When grown on xylose under aerobic conditions, the strain with pXOR had up to 1...
