  • Patent number: 9493802
    Abstract: The invention provides recombinant GH61 proteins obtained from Myceliophtora thermophila, and nucleic acids that encode such proteins. The invention also provides protein fractions isolated from M. thermophila supernatant that have GH61 protein activity. These preparations can be used to increase yield of products from reactions in which a cellulose-containing substrate undergoes saccharification by one or more cellulase enzymes, such as endoglucanase, ?-glucosidase, or cellobiohydrolase. Combinations of GH61 protein and cellulases can be used to break down cellulosic biomass into fermentable sugars in the production of ethanol.

  • Patent number: 8951758
    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.

  • Patent number: 8546109
    Abstract: The present invention relates to a method for lignocellulosic conversion to sugar using an ionic liquid pretreatment for the saccharification of lignocellulosic biomass. Thus, cellulose, hemicellulose, when hydrolyzed into their sugars, can be converted to ethanol fuel through well-established fermentation technologies. These sugars also form the feedstocks for production of a variety of chemical and polymers. The complex structure of the biomass required pretreatment to enable efficient saccharification of cellulose and hemicellulose components to their constituent sugars.
