    Abstract: The present invention relates to asparaginase variants. The present invention also relates to polynucleotides encoding the variants; nucleic acid constructs, vectors, and host cells comprising the polynucleotides; and methods of using the variants. The further relates to a process of producing a fermentation product, comprising: liquefying a starch-containing material to dextrins with an alpha-amylase in the presence of an asparaginase of the invention; saccharifying the dextrins to a sugar with a glucoamylase; and fermenting the sugar using a fermenting organism.

    Abstract translation: 本发明涉及天冬酰胺酶变体。 本发明还涉及编码这些变体的多核苷酸; 核酸构建体,载体和包含多核苷酸的宿主细胞; 以及使用这些变体的方法。 本发明进一步涉及一种生产发酵产物的方法,包括:在本发明的天冬酰胺酶存在下,将含淀粉的物质用α-淀粉酶液化; 将糊精糖化成糖与葡糖淀粉酶; 并使用发酵生物发酵糖。
