Bruce A. Strohm has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Process for hydrolyzing starch without pH adjustment
    Publication number: 20080145900
    Abstract: An alpha-amylase enzyme obtained from Bacillus acidocaldarius species is utilized to liquefy starch at a pH as low as 3.0 without the need to add thermostabilizing agents such as calcium. The alpha-amylase produces acceptable DE yields in a single liquefaction step and does not need to be inactivated prior to conducting saccharification which can proceed without adjustment of the pH of the liquefact. Alternatively, a secondary liquefaction process can be utilized, in which case two additions of the alpha-amylase are used resulting in a combined low dosage of the enzyme.

  • Expression of granular starch hydrolyzing enzymes in and process for producing glucose from granular starch substrates
    Patent number: 7303899
    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.
