Abstract
The present disclosure relates to methods for using one or more polypeptides with phytase activity in grain processing, ethanol, and biofuel production.
Claims21
A method for improving efficiency of ethanol production by yeast, the method comprising:
- (a) providing a variant polypeptide comprising an amino acid sequence that is at least 85% identical to the amino acid sequence as set forth in amino acid residues 23-434 of SEQ ID NO:2 or that is at least 85% identical to the amino acid sequence as set forth in SEQ ID NO:3;
- wherein said variant polypeptide has phytase activity;
- and
- (b) adding the variant polypeptide to an ethanol processing fluid in an ethanol production facility,
- wherein addition of the variant polypeptide improves ethanol production efficiency comprising one or more of:
- increased yeast cell count, yeast budding or yeast viability;
- increased ethanol yield, decreased glycerol levels, or decreased total sugar levels;
- decreased fouling rate;
- increased phosphorous levels;
- and
- increased operation time of the ethanol production facility.
