Summary
Two types of processes have been applied for the pretreatment of lignocellulosic materials in order to render them easily degradable by the cellulase of Trichoderma viride. They were compared at different temperatures, with regard both to the residual dry mass and the improvement in accessibility to the enzyme complex. The latter was measured in terms of glucose liberated, which was quantified by HPLC. Hydrothermolysis proved more effective than the organosolv process for the pretreatment of wheat straw, and vice versa for poplar wood. In terms of the percentage of glucan enzymatically converted to glucose, yields up to 90% could be achieved.
