CABBI researchers determine enzyme dosages for 2G ethanol production
In Illinois, lignocellulolytic enzymes are a primary cost constraint in second-generation ethanol biorefineries, accounting for up to 30% of operating expenses. Because it requires limited inputs and can achieve industrially viable ethanol titers and yields with an inexpensive nitrogen source, the hydrothermal pretreatment approach is a leading biorefinery technique.
However, enzyme loadings reported in the literature vary widely, and optimization among diverse bioenergy feedstocks has not been systematically investigated, hindering cost assessments.
Researchers at the Center for Advanced Bioenergy and Bioproducts Innovation (CABBI) assessed enzyme dosages (ED) of cellulase and hemicellulase on hydrothermally pretreated lignocellulosic substrates to maximize sugar and ethanol yields and improve cost analysis. The findings are published in the journal Green Chemistry.
