WASHINGTON—A commercial enzyme could reduce overall costs linked with producing ethanol from grain, and also reduce associated emissions of greenhouse gases, according to a study by U.S. Department of Agriculture (USDA) scientists and colleagues.

The researchers found that the enzyme helps extract water from an ethanol byproduct used to make dried distillers grains with solubles (DDGS), which can be used as feed supplements for cattle, swine and poultry. This could significantly reduce the amount of electricity, natural gas, energy and water needed for production of grain ethanol and its marketable byproducts. Results from this study were published in the scientific journal Industrial Biotechnology.
