  • Dry solids staging fermentation process
    Patent number: 8980598
    Abstract: A dry solids staging fermentation process for producing an end-product, such as ethanol is disclosed said process including an initial fermentation step including combining a first fermentable substrate with one or more starch hydrolyzing enzymes and fermenting organisms in a fermentation vessel and a loading step which includes adding a second fermentable substrate to the fermentation vessel wherein the percent dry solids (% DS) of the fermentation broth increases over time.

  • Methods for producing end-products from carbon substrates
    Publication number: 20070141660
    Abstract: The present invention provides means for the production of desired end-products of in vitro and/or in vivo bioconversion of biomass-based feed stock substrates, including but not limited to such materials as starch and cellulose. In particularly preferred embodiments, the methods of the present invention do not require gelatinization and/or liquefaction of the substrate.

  • Expression of granular starch hydrolyzing enzymes in Trichoderma and process for producing glucose from granular starch substrates
    Publication number: 20050136525
    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.
