Top Ethanol Producer, ISU Expert Team Up
By Mr Ethanol | March 3, 2008
Dubuque Telegraph Herald:
The nation’s top ethanol producer is teaming with an Iowa State University researcher in hopes of squeezing more ethanol out of a kernel of corn.
Sioux Falls-based Poet LLC already uses a process called BPX, which converts starch to sugar and then ferments it to ethanol without the use of heat or cooking. Poet uses the method in 20 of its 22 ethanol plants and estimates it can get 3 gallons of ethanol from each bushel of corn compared with an industry standard of 2.7 gallons per bushel.
Poet is working with Jay-lin Jane, a carbohydrate chemist and professor in Iowa State’s food science and human nutrition department, to look at differences between starches in various varieties of corn.
The goal is to identify which lines of corn starches are more easily broken down into glucose by the enzyme used for conversion.
The glucose is then fermented into ethanol and carbon dioxide.
