Researchers Use Fungus to Improve Corn Ethanol Process

Posted on May 27, 2008

Pilot-scale airlift reactor with external recycling for fungal processing of thin stillage. Spore inoculation occurred on Day 0 (left). Fungal pellets filled the reactor by Day 3 (right). Click to enlarge.Growing a fungus in the thin stillage resulting from dry-mill ethanol production can reduce energy costs by as much as one-third, recycle more water and improve the distillers dried grains byproduct, according to a team of researchers from Iowa State University and the University of Hawai i.The Iowa State project is focused on using fungi to clean up and improve the dry-grind ethanol produc...
