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.

Processes for producing fermentation products

The inventors have identified amylases in fungal strains ofand found that the amylase can increase the shelf life of baked products. Particularly, the novel amylase in combination with a maltogenic amylase further improves the softness of bread crumb without having detrimental effects on elasticity.

Amylase

An isolated polynucleotide comprising an open reading frame encoding a polypeptide having alpha-amylase activity, the polypeptide selected from the group consisting of: a) a polypeptide comprising an amino acid sequence which has at least 70% identity with amino acids 22 to 450 of SEQ ID NO:4; b) a polypeptide comprising an amino acid sequence which has at least 70% identity with the polypeptide encoded by the amylase encoding part of the polynucleotide inserted into a plasmid present in thehost deposited under the Budapest Treaty with DSMZ under accession number DSM 15334; c) a polypeptide encoded by a polynucleotide comprising a nucleotide sequence which has at least 70% identity with the sequence shown from position 68 to 1417 in SEQ ID NO:3; and d) a fragment of (a), (b) or (c) that has alpha-amylase activity.
