Abstract
The present invention relates to processes for producing fermentation products from starch-containing material, wherein an alpha-amylase and a thermostable endoglucanase is present and/or added during liquefaction. The invention also relates to compositions suitable for use in processes of the invention.
Claims20
A process for producing fermentation products from starch-containing material comprising the steps of:
- i) liquefying the starch-containing material at a temperature from 75-95° at a pH from 4-6 using:
- an alpha-amylase;
- an endoglucanase having a Melting Point (DSC) above 80° C.;
- ii) saccharifying using a carbohydrate-source generating enzyme;
- and
- iii) fermenting using a fermenting organism.
The process of claim 6, wherein the protease has at least 90%, but less than 100%, sequence identity to the mature polypeptide of SEQ ID NO:
- 2.
A process of producing liquefied starch, comprising liquefying a starch-containing material with a composition comprising:
- i) an alpha-amylase;
- ii) an endoglucanase having a Melting Point (DSC) above 80° C.;
- iii) a protease;
- and
- iv) optionally a carbohydrate-source generating enzyme.
