Abstract
A method for increasing the oil yield in an ethanol production process comprising: adding a liquid enzyme formulation having at least one enzyme, a buffering agent, a stabilizer, and a preservative wherein the pH of the enzyme formulation is about pH 6.0-8.0 to a beer, a distillation, a whole stillage, a centrifugation, a thin stillage, an evaporator, a syrup, or an oil recovery unit.
Claims15
A method for increasing the oil yield in an ethanol production process comprising:
- adding a liquid enzyme formulation having an alpha-amylase titrated from a pH of 8.0 to 10.5, a buffering agent, a stabilizer, and a preservative wherein the pH of the enzyme formulation is about pH 6.0-8.0 to a beer, a distillation, a whole stillage, a centrifugation, a thin stillage, an evaporator, a syrup, or an oil recovery unit, and wherein the alpha-amylase comprises an amino acid sequence having at least 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 100% sequence identity to one of the amino acid sequences set forth in SEQ ID NO:1, SEQ ID NO:2, SEQ ID NO:3, SEQ ID NO:4, SEQ ID NO:5, SEQ ID NO:6, SEQ ID NO:7, SEQ ID NO:8, SEQ ID NO:9, SEQ ID NO:10, SEQ ID NO:11, SEQ ID NO:12, SEQ ID NO:13, and SEQ ID NO:14.
