Abstract

Two previously reported mutants ofPachysolen tannophilus, which accumulate ethanol more rapidly and in greater yield than the wild-type NRRL Y2460, have been cross-mated. Aneth 2-1 mutant which is unable to grow on ethanol, was mated with the mutant NO3−NO3-4 which possesses increased levels of pentose phosphate pathway enzymes. The new hybrid strain combines the properties of both parents and possesses improved characteristics for xylose fermentation to ethanol.
