摘要：

This study aim to enhance biogas production for the co-digestion of rice straw and soybean straw (RSS), pretreatment of fermentation materials by Trichoderma reesei RUT C30 were investigated. The pretreatments were done at 30 degrees C for 72 h, and anaerobic digestion for 5 weeks. The results showed that the cumulative biogas yield from pretreatment co-digestion group RSS (214.1 NmL/g TSsubstrate) was 318% higher than the untreated group CG RSS (51.2 NmL/g TSsubstrate). The cumulative methane yield from RSS was 94.3 NmL CH4/g TSsubstrate, which was 807% higher than that of untreated group (CG RSS 10.4 NmL CH4/g TSsubstrate), and 90% of potential biogas generation was reached in 17 days, which was 39% shorter than that of pretreatment mono-digestion groups (28 days). These results suggested that rice and soybean straw co-digestion exhibits a positive synergistic effect and Trichoderma reesei RUT C30 provides an effective method for improving biogas production.
