  • Patent number: 8071350
    Abstract: In one aspect, the invention is directed to polypeptides having an amylase activity, polynucleotides encoding the polypeptides, and methods for making and using these polynucleotides and polypeptides. The polypeptides of the invention can be used as amylases to catalyze the hydrolysis of starch into sugars.

  • Patent number: 8058033
    Abstract: The present disclosure relates to variants of a parent glucoamylase having altered properties (e.g., improved thermostability and/or specific activity). In particular, the present disclosure provides compositions comprising the variant glucoamylases, including starch hydrolyzing compositions and cleaning compositions. The disclosure also relates to DNA constructs encoding the variants and methods of producing the glucoamylase variants in host cells.

  • Patent number: 8048657
    Abstract: The present invention relates to an enzyme blend composition comprising a glucoamylase, an acid stable alpha amylase, and an acid fungal protease. The present invention is further directed to a method for producing end products such as alcohols from fermentable sugars, comprising the steps of: (a) contacting a slurry comprising a milled grain that contains starch with an alpha amylase to produce a liquefact; (b) contacting the liquefact with a glucoamylase, an acid stable alpha amylase, and an acid fungal protease, to produce fermentable sugars; and (c) fermenting the fermentable sugars in the presence of a fermenting organism to produce end products.

  • Patent number: 8034590
    Abstract: The present invention relates to filamentous fungal host cells and particularly Trichoderma host cells useful for the production of heterologous granular starch hydrolyzing enzymes having glucoamylase activity (GSHE). Further the invention relates to a method for producing a glucose syrup comprising contacting a granular starch slurry obtained from a granular starch substrate simultaneously with an alpha amylase and a GSHE at a temperature equal to or below the gelatinization temperature of the granular starch to obtain a composition of a glucose syrup.
