    摘要: An improved dry grind system and method for producing a sugar stream from grains or similar carbohydrate sources and/or residues, such as for biochemical production, with front end oil separation. Prior to or after saccharification, oil can be removed from a sugar/carbohydrate stream. After saccharification and prior to a sugar conversion process, the sugar/carbohydrate stream includes a desired Dextrose Equivalent (DE) where DE describes the degree of conversion of starch to dextrose can be produced, with such sugar stream being available for biochemical production, e.g., alcohol production, or other processes. In addition, the systems and methods also can involve the removal of certain grain components, e.g., corn kernel components, including protein and/or fiber. In other words, oil separation and sugar stream production occurs on the front end of the system and method.

    摘要: An improved dry grind system and method for producing a sugar stream from grains or similar carbohydrate sources and/or residues, such as for biofuel production. In particular, a sugar/carbohydrate stream, which includes a desired Dextrose Equivalent (DE) where DE describes the degree of conversion of starch to dextrose (aka glucose) and/or has had removed therefrom an undesirable amount of unfermentable components, can be produced after saccharification and prior to fermentation (or other sugar conversion process), with such sugar stream being available for biofuel production, e.g., alcohol production, or other processes. In addition, the systems and methods also can involve the removal of certain grain components, e.g., corn kernel components, including protein, oil and/or fiber, prior to fermentation or other conversion systems. In other words, sugar stream production and/or grain component separation occurs on the front end of the system and method.

    摘要: The present invention relates to a method of making glucose syrup from liquefied starch comprising, (a) contacting the liquefied starch with a glucoamylase, a pullulanase, and optionally an alpha-amylase wherein the ratio of pullulanase dose expressed as NPUN/gDS, to alpha-amylase dose expressed as FAU(A)/gDS is at least 60, particularly at least 75, particularly at least 100, more particularly at least 150, more particularly at least 200, more particularly at least 250, more particularly at least 300, more particularly at least 400, more particularly at least 500, more particularly at least 600, more particularly at least 800 or if no alpha-amylase is present the pullulanse is present in a dose of at least 0.5, particularly at least 0.75, particularly at least 1.0, particularly at least 1.5 NPUN/gDS, and (b) saccharifying the liquefied starch.

    摘要: The present invention relates to a method for solubilising arabinoxylan-containing material (particularly insoluble arabinoxylan-containing material), comprising admixing a xylan-containing material with a xylanase comprising a polypeptide sequence shown herein as SEQ ID No. 3, SEQ ID No. 2, SEQ ID No. 1, SEQ ID No. 9, SEQ ID No. 10, SEQ ID No. 11 or SEQ ID No. 15, or a variant, homologue, fragment or derivative thereof having at least 75% identity with SEQ ID No. 3 or SEQ ID No. 2 or SEQ ID No. 1 or SEQ ID No. 9 or SEQ ID No. 10 or SEQ ID No. 11 or SEQ ID No. 15; or a polypeptide sequence which comprises SEQ ID No. 3, SEQ ID No. 2, SEQ ID No. 1, SEQ ID No. 9, SEQ ID No. 10, SEQ ID No. 11 or SEQ ID No. 15 with a conservative substitution of at least one of the amino acids; or a xylanase which is encoded by a nucleotide sequence shown herein as SEQ ID No. 6, SEQ ID No. 5, SEQ ID No. 4, SEQ ID No. 12, SEQ ID No. 13, SEQ ID No. 14, SEQ ID No. 16, SEQ ID No.17 or SEQ ID No. 18, or a nucleotide sequence which can hybridize to SEQ ID No. 6, SEQ ID No. 5, SEQ ID No. 4, SEQ ID No. 12, SEQ ID No. 13, SEQ ID No. 14, SEQ ID No. 16, SEQ ID No.17 or SEQ ID No. 18 under high stringency conditions, or a nucleotide sequence which has at least 75% identity with SEQ ID No. 6, SEQ ID No. 5, SEQ ID No. 4, SEQ ID No. 12, SEQ ID No. 13, SEQ ID No. 14, SEQ ID No. 16, SEQ ID No.17 or SEQ ID No. 18, or a nucleotide sequence which differs from SEQ ID No. 6 or SEQ ID No. 5 or SEQ ID No. 4 or SEQ ID No. 12 or SEQ ID No. 13 or SEQ ID No. 14 or SEQ ID No. 16 or SEQ ID No.17 or SEQ ID No. 18 due to the degeneracy of the genetic code, or a xylanase obtainable (or obtained) from Fusarium verticilloides. The present invention also relates to a novel xylanase comprising (or consisting of) a polypeptide sequence shown herein as SEQ ID No. 3, SEQ ID No. 2 or SEQ ID No. 1, or a variant, homologue, fragment or derivative thereof having at least 99% identity with SEQ ID No. 3 or SEQ ID No. 2 or SEQ ID No. 1; or a xylanase which is encoded by a nucleotide sequence shown herein as SEQ ID No. 6, SEQ ID No. 5 or SEQ ID No. 4, or a nucleotide sequence which can hybridize to SEQ ID No. 4 or SEQ ID No. 5 under high stringency conditions, or a nucleotide sequence which has at least 97.7% identity (preferably 98% identity) with SEQ ID No. 6, SEQ ID No. 5 or SEQ ID No. 4. The present invention yet further relates to methods relating to feedstuffs, malting and brewing, processing of grain-based materials such as during the production of bioethanol or biochemical (e.g. bio-based isopropanol), or wheat gluten-starch separation processes and the like.
