New enzyme technology removes the need for
energy-intensive, costly cook step
Genencor
International, Inc.
announced today the availability of novel enzyme technology for
the ethanol industry that could lead to improved energy balance
and reduced production costs while obtaining higher output.
The first product from its line
of STARGEN™ granular starch hydrolyzing enzymes was introduced
this week at the Fuel Ethanol Workshop in Kansas City, MO. The
new technology has the potential to pave the way for the
emergence of biorefineries.
Until recently, 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 glucoamylase that
convert granular or uncooked starch to fermentable sugars on a
continuous basis through a simultaneous saccharification and
fermentation process.
Some of the potential
advantages of this new technology include improved productivity,
reduced energy consumption, higher ethanol yields and savings on
capital expenses by reducing overall unit operations.
“This new, low energy
technology offers the ethanol industry significant added value
with fewer processing steps requiring less energy, materials and
capital. It should be equally useful to producers to accelerate
the development of biobased manufacturing processes and products
that require low-cost carbon,” said Thomas J. Pekich, president
of Genencor International.
“Together, technology advances
like STARGEN™ enzymes will lead to a more sustainable
environment and lessen dependence on foreign oil.”
Genencor has achieved a high
level of enzyme expression in industrial production strains
while creating an acceptable cost structure for widespread use.
Genencor is also evaluating applications of the STARGEN™
technology for use in its other businesses.
