  • Publication number: 20170159035
    Abstract: The present invention provides various GH61 protein variants comprising various amino acid substitutions. The GH61 protein variants have an improved ability to synergize with cellulase enzymes, thereby increasing the yield of fermentable sugars obtained by saccharification of biomass. In some embodiments, sugars obtained from saccharification are fermented to produce numerous end-products, including but not limited to alcohol.

  • Publication number: 20150017696
    Abstract: The present disclosure relates to recombinant host cells comprising one or more recombinant polynucleotides encoding enzymes in select pathways that provide the ability to use the cells to produce 1,3-butadiene. The present disclosure also provides methods of manufacturing the recombinant host cells, and methods for the use of the cells to produce 1,3-butadiene, either through formation of the intermediate compound crotonol followed by chemo-catalytic dehydration to 1,3-butadiene, or through the use of a recombinant cell comprising a fully enzymatic pathway capable of converting crotonyl-CoA or crotonyl-ACP to crotonol and then crotonol to 1,3-butadiene.
