Corn silage was treated by white rot fungi (WRF) to investigate the effect of pretreatment on material's ability to produce methane in anaerobic digestion (AD). The selective fungi Pleurotus ostreatus and Dichomitus squalens promoted biogas generation, whereas the non-selective Trametes versicolor and Irpex lacteus had negative effect. Cumulative methane production after 10-day pretreatment with P. ostreatus at 28 °C rose 1.55-fold. The longer pretreatments of 30 and 60-days had smaller effect. When the pretreatment with P. ostreatus was carried out at 40 °C a high HS release affected the AD process. Effect of WRF action dependent on the type of corn silage. With typical corn silage, the lignin depolymerisation raised the methane generation from 0.301 to 0.465 mkg. In contrast, extensive decomposition of hemicellulose in hybrid corn silage deteriorated the effect of pretreatment on methane production.
用白腐真菌（WRF）处理玉米青贮饲料，研究预处理对厌氧消化（AD）中物料产甲烷能力的影响。选择性真菌糙皮侧耳和斜卧青霉促进沼气生成，而非选择性的变色栓菌和乳白栓菌则有负面影响。在 28°C 下用糙皮侧耳预处理 10 天，累积甲烷产量增加了 1.55 倍。30 天和 60 天的较长预处理效果较小。当在 40°C 下用糙皮侧耳进行预处理时，高 HS 释放会影响 AD 过程。WRF 作用的效果取决于玉米青贮饲料的类型。对于典型的玉米青贮饲料，木质素解聚将甲烷生成从 0.301 提高到 0.465 mkg。相比之下，杂交玉米青贮饲料中半纤维素的广泛分解降低了预处理对甲烷生成的效果。
