  • Publication number: 20100144575
    Abstract: The present invention relates to a method of constructing a variant of a parent Termamyl-like ?-amylase, which variant has ?-amylase activity and at least one altered property as compared to the parent ?-amylase, comprises i) analysing the structure of the parent Termamyl-like ?-amylase to identify at least one amino acid residue or at least one structural part of the Termamyl-like ?-amylase structure, which amino acid residue or structural part is believed to be of relevance for altering the property of the parent Termamyl-like ?-amylase (as evaluated on the basis of structural or functional considerations), ii) constructing a Termamyl-like ?-amylase variant, which as compared to the parent Termamyl-like ?-amylase, has been modified in the amino acid residue or structural part identified in i) so as to alter the property, and, optionally, iii) testing the resulting Termamyl-like ?-amylase variant with respect to the property in question.

  • Patent number: 7727726
    Abstract: The presently disclosed subject matter provides improved processes for processing starch from plant sources, including processes for starch liquefaction, for simultaneous liquefaction and saccharification, and for the preparation of ethanol. These processes can be performed without a pH adjustment and at relatively low temperatures. The processes can involve the use of starch-containing plant material derived from plants that express starch-digesting enzymes. The presently disclosed subject matter further relates to improved processes for the preparation of other starch-derived products, including dried distiller grain (dried distiller grain) and dried distiller grain and solubles (dried distiller grain and solubles), and to the starch-derived products, themselves.
