Abstract

The effects of fungal pretreatment on the rapeseed straw, was evaluated after solid state cultivation of white rot fungi Phanerochaete Chrysosporium. P. Chrysosporium degraded the lignin during the pretreatment, and the pretreated straw showed increases in enzymatic hydrolysis ratios (3-fold after 15- day pretreatment).The samples were identified by FTIR and XRD. Xray analysis showed that pretreated samples had a higher crystallinity than untreated samples (39.47% for a pretreated sample compared to 33.17% at untreated) and FTIR spectroscopy demonstrated that the content of lignocellulose decreased during the biological pretreatment process. Moreover, the biological pretreatment slowed down the decline in hydrolysis rate during enzymatic hydrolysis.
