Processes for producing fermentation products and compositions used therein

A process for producing fermentation products from starch-containing material comprising the steps of:

• i) liquefying the starch-containing material at a temperature above the initial gelatinization temperature using an alpha-amylase;
• ii) saccharifying using a glucoamylase;
• iii) fermenting using a fermenting organism;
• wherein at least one polypeptide having beta-1,6-glucanase activity and at least one polypeptide having endo-and/or exo-beta-1,3-glucanase activity are present or added during saccharifying step ii) or fermenting step iii).

A process for producing fermentation products from cellulosic-containing material comprising the steps of:

• i) optionally pretreating a cellulosic-containing material;
• ii) saccharifying a cellulosic-containing material and/or pretreated cellulosic-containing material using a glucoamylase;
• and
• iii) fermenting using a fermenting organism;
• wherein at least one polypeptide having beta-1,6-glucanase activity and at least one polypeptide having endo-and/or exo-beta-1,3-glucanase activity are present or added during saccharifying step ii) or fermenting step iii).
