Increasing Fermentation Rates and Efficiency with Enzyme Solutions for Starch-based Fuel Ethanol
DuPont's innovative enzyme technology enables the production of more than 68 billion liters of first-generation bioethanol each year. This is estimated to save around 31 million metric tons of CO2 from being released into the atmosphere.
By increasing yields, speeding up fermentation, and reducing energy and chemical consumption, DuPont is helping ethanol producers meet the challenges of increasing feedstock and energy costs with innovative enzyme solutions for starch-based fuel ethanol.
For example, the SPEZYME® line of alpha amylase enzymes offers many advantages in the production of fuel ethanol from starch, including robust liquefaction and viscosity reduction at various temperatures and pH levels. Combined with products such as DuPont™ FermaSure® XL, a fermentation additive that rapidly attacks and decreases harmful bacteria, ethanol producers are increasing their ethanol fermentation rates and efficiency.*
Starch-based, or first generation bioethanol is already making a significant contribution to the ambitious targets for renewable energy set in the USA and EU. On a life cycle basis, ethanol produced from corn results in about a 20% reduction in greenhouse gas emissions relative to gasoline. With improved efficiency and use of renewable energy, this reduction could be as much as 52%. Importantly, today’s starch-based ethanol industry has laid the foundations for cellulosic and other advanced biofuels by developing critical infrastructure.
With laboratories in Iowa, USA, Wuxi, China and Leiden, The Netherlands, we continue to invest in starch-based fuel ethanol enzymes and applications to enhance liquefaction and SSF (simultaneous saccharification and fermentation). Our dedicated Sales and Application team works closely with customers to identify the best products for their specific applications and challenges.
