  • Publication number: 20140178954
    Abstract: Expression of a xylose isomerase in a yeast cell that expresses the chaperonins GroES and GroEL was found to result in enzymatically active xylose isomerase, while there is little to no activity with expression of the bacterial xylose isomerase in a yeast cell lacking GroES and GroEL. A yeast cell expressing xylose isomerase activity, and a complete xylose utilization pathway, provides a yeast cell that can produce a target compound, such as ethanol, butanol, or 1,3-propanediol, using xylose derived from lignocellulosic biomass as a carbon source.

  • Patent number: 8569458
    Abstract: Xylose-utilizing, ethanol producing strains of Zymomonas mobilis with improved performance in medium comprising biomass hydrolysate were isolated using an adaptation process. Independently isolated strains were found to have independent mutations in the same coding region. Mutation in this coding may be engineered to confer the improved phenotype.
