Novozymes has launched of a new enzyme that makes it possible to produce more ethanol from the same amount of corn.
The product, Spirizyme Excel, converts more starch in corn, wheat, and other feedstocks into sugars which can be fermented to ethanol, thereby allowing producers to increase yields by more than one percent. Compared to other available solutions, a typical ethanol plant can gain $1 million or more per year using the enzyme, according to the company.
Unlike other starch-converting enzymes, Spirizyme Excel breaks down the most difficult starch fractions in the feedstock to maximize biofuel production yields. The greater the starch conversion, the higher the output of ethanol.
Today, an average acre of corn will yield roughly 440 gallons of ethanol. Corn yields have improved by 70% per acre and ethanol plants can get 50% more ethanol out of the corn compared to 1977.
Novozymes has achieved great breakthroughs in cellulosic biofuel recently, but this does not mean we have forgotten about corn ethanol. We have delivered market-leading innovation to this industry for a long time and we will continue to do so both for corn and cellulosic ethanol.
