Enzyme technology for cheaper ethanol

Genencor Int Inc has announced the availability of novel enzyme technology for the ethanol industry which it says reduces production costs and increases yields.
The first products from its line of Stargen’s granular starch hydrolyzing enzymes .has the potential to pave the way for the emergence of biorefineries, it says.
Hitherto, it says Genencor Int Inc has announced the availability of novel enzyme technology for the ethanol industry which it says reduces production costs and increases yields.
The first products from its line of Stargen’s granular starch hydrolyzing enzymes .has the potential to pave the way for the emergence of biorefineries, it says.
Hitherto, it says, ethanol plants have cooked grains and other feedstocks with thermostable enzymes .to begin the process of converting starch to fermentable sugars and ultimately to ethanol.
Genencor’s Stargen enzymes .include blends of an alpha amylase and a gluco amylase that convert granular or uncooked starch to fermentable sugars on a continuous basis through a simultaneous saccharification and fermentation process.
Stargen enzymes .are better environmentally and lessen dependence on foreign oil, it says.
Jacqui Finegan of SK Chemtrade, Genencor’s agent in South AFrica, said any new distillery project in SA would use this technology. It would be used because it would reduce capital and energy costs and improve the quality of the protein waste.
The process was at a much lower temperature when maize was used – at 32°C, compared with 92°C The technology had been successfully tested in corn and rye distilleries in the US, although it was not in commercial applications there yet, she said.
