NOVELTY - Producing a fermentation product from starch-containing material comprises simultaneously saccharifying and fermenting starch-containing material using a carbohydrate-source generating enzymes and a fermenting organism at a temperature below the initial gelatinization temperature of the starch-containing material in the presence of a metalloprotease.    USE - The metalloprotease is useful in the process for fermenting gelatinized and/or ungelatinized starch-containing material into a fermentation product and the metalloprotease and pullulanase are useful in the process for fermenting gelatinized starch containing material into a fermentation product e.g. an alcohol, preferably ethanol, as a fuel ethanol, potable ethanol and/or industrial ethanol (all claimed), methanol, butanol, organic acids (e.g. citric acid, acetic acid, itaconic acid, lactic acid, succinic acid and gluconic acid), ketones (e.g. acetone), amino acids (e.g. glutamic acid), gases (e.g. hydrogen and carbon dioxide), antibiotics (e.g. penicillin and tetracycline), enzymes, vitamins (e.g. riboflavin and beta-carotene), and hormones, where the ethanol is useful as e.g. drinking ethanol, industrial ethanol or products used in the consumable alcohol industry (e.g. beer and wine) and dairy industry (e.g. fermented dairy products).    ADVANTAGE - The combination of metalloprotease and pullulanase boost the ethanol yields more than either the metalloprotease or pullulanase alone.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) a process for producing a fermentation product from starch-containing material, comprising: liquefying starch-containing material in the presence of an alpha-amylase; saccharifying the liquefied material using a carbohydrate source generating enzyme; and fermenting using a fermenting organism, where a metalloprotease is present during fermentation and/or, before, during and/or after liquefaction; and    (2) a composition comprising either: a metalloprotease, a carbohydrate-source generating enzyme and an alpha-amylase; or a metalloprotease and a pullulanase.
