Biofuels: Fungus Use Improves Corn-to-ethanol Process

Scientists are developing a process that cleans up and improves the dry-grind ethanol production process. The process uses fungus to reduce energy costs, allow more water recycling and improve a co-product that's used as livestock feed. The process could change ethanol production in dry-grind plants so much that energy costs can be reduced by as much as one-third, according to researchers.
