Improvements in Enzymes for Cellulosic Ethanol

Recommendations

Info

Future improvements for enzyme efficacy driven by active RnD today! Reduce product inhibition of enzymes Increase ethanol tolerance of enzymes Increase thermo tolerance of enzyme suite Increase hemicellulase activity Reduce ineffective binding/ interaction with substrate Increase specific activity of enzymes = Improved Process Economics 20
Summary ACCELLERASE ® 1500 provides a new benchmark for process developers and plant designers. ACCELLERASE ® XY, XC, and BG are accessory enzyme products for small-scale process development that will enhance biomass hydrolysis and ethanol production. These enzymes offer a wide range of activities and synergies that allow for greater flexibility with multiple different feedstocks and pretreatment technologies. Genencor is actively working on future generations of Accellerase ® products. Cost of enzymes has already come a long way, and is projected to improve significantly in coming years. 21
