Researchers at Iowa State University are working to squeeze every available drop of ethanol from a corn kernel. According to this UPI story, “they are working to create chemical catalysts that would increase the yield of fermentable sugars from corn.” The research is supported by grants of $305,000 from the National Science Foundation, $200,000 from the U.S. Department of Agriculture and $162,000 from the U.S. Department of Energy.
