Abstract

The mushroom cultured waste(MCW) from cork oak was evaluated as the raw material for bioethanol production. For enzymatic hydrolysis, cellulase cocktails (Celluclast 1.5L and Novozym 188) was used for polysaccharides to monosaccharides conversion. Compared with sound cork oak woodmeal, woodmeal from MCW showed higher cellulose to glucose conversion. To improve polysaccharides to monosaccharides conversion, pretreatment by sodium hydroxide was applied. Even though more xylan and lignin were removed in woodmeal of MCW than that of cork oak, concentration of glucose was higher from sodium hydroxide treated cork oak woodmeal (51.3 g/L) than treated MCW woodmeal (41.6 g/L).
