In this study fungal pretreatment of non-sterile tall wheat grass via the white rot fungi Flammulina velutipes was studied and the effect on biodegradability of lignocellulosic biomass and methane production, was evaluated. Degradation of lignin, cellulose, hemicellulose, and dry matter in non-sterile tall wheat grass during 28 days of fungal pretreatment using different inoculum ratio (0%-50%) and moisture content (MC) (45% MC, 65% MC, and 75% MC) were assessed via comparison to untreated biomass. Pretreatment with F. velutipes was most effective at 65% MC and 40% inoculum ratio, resulting in 22% lignin removal. The corresponding methane yields were 181.3 Ndm·kg VS, which were 280% higher than for the untreated tall wheat grass.
本研究通过白腐真菌金顶侧耳对非无菌高羊茅进行真菌预处理，并评估其对木质纤维素生物质生物降解性和甲烷生成的影响。通过与未处理的生物质进行比较，评估了在不同接种比例（0%-50%）和水分含量（MC）（45%MC、65%MC 和 75%MC）下，非无菌高羊茅在 28 天的真菌预处理过程中木质素、纤维素、半纤维素和干物质的降解情况。在 65%MC 和 40%接种比例下，金顶侧耳预处理效果最佳，木质素去除率为 22%。相应的甲烷产量为 181.3 Ndm·kg VS，比未经处理的高羊茅高出 280%。
