The present disclosure relates to methods for using one or more polypeptides with phytase activity in grain processing, ethanol, and biofuel production.

Methods for using phytase in ethanol production

Polypeptides having phytase activity and polynucleotide sequences encoding the phytases are provided. The gene expresses the phytase at a level of at least 7 g/L to 40 g/L. The phytase have higher specific activity, retain activity at low pH, and retain activity at high temperature. The phytase can be used in a variety of compositions including food, feed, pharmaceuticals, and cleaning.

Phytase

Polypeptides having phytase activity and polynucleotide sequences encoding the phytases are provided. The gene expresses the phytase at a level of at least 7 g/l to 40 g/L. The phytases have higher specific activity, retain activity at low pH, retain activity at high temperature, increased phosphorous equivalency, increased phosphorous bioavailability, and increased phosphorous hydrolysis. The phytases can be used in a variety of industries including food, feed, ethanol production, pharmaceuticals, and cleaning.

This invention relates to phytases, polynucleotides encoding them, uses of the polynucleotides and polypeptides of the invention, as well as the production and isolation of such polynucleotides and polypeptides. In particular, the invention provides polypeptides having phytase activity under high temperature conditions, and phytases that retain activity after exposure to high temperatures. The invention further provides phytases which have increased gastric lability. The phytases of the invention can be used in foodstuffs to improve the feeding value of phytate rich ingredients. The phytases of the invention can be formulated as foods or feeds or supplements for either to, e.g., aid in the digestion of phytate.
