Investigation of the Potential Suitability of the Enzymes Produced by the Fungus Thermoascus Aurantiacus for the Pretreatment of Lignocellulose for Bioethanol Production

A. Boyce & G. Walsh
Second¬ generation biofuels, produced from lignocellulosic biomass, can reduce greenhouse gas emissions without competing with food production. The conversion of lignocellulosic feedstocks to bioethanol can be undertaken by enzymatic hydrolysis of pretreated lignocellulosic material with subsequent fermentation of the resulting sugars to ethanol. Pre¬treatment is commonly undertaken by dilute¬ acid pretreatment involving treatment of the lignocellulosic material with acid (0.1¬5%) at temperatures of 140¬220°C. This study focuses on the potential application of enzymes in this...
