Iowa State researchers feed pigs, chickens high-protein
fungus grown on ethanol leftovers
Initial studies show a fungus grown in the leftovers of
ethanol production could be a good energy feed for pigs and chickens.
In separate feeding trials, nursery pigs and chickens have
eaten high-protein fungi that Hans van Leeuwen and other Iowa State University
researchers have produced in a pilot plant that converts ethanol leftovers into
food-grade fungi. The production process also cleans some of the water used to
produce ethanol, boosting the amount of water that can be recycled back into
biofuel production and saving energy on water cleanup and co-product recovery.
