Maize stover, rice straw, oil palm fronds and sugarcane bagasse were treated with the white-rot fungi Ceriporiopsis subvermispora, Lentinula edodes, Pleurotus eryngii, or Pleurotus ostreatus at 24 °C for 0-6 weeks. The fungi increased total gas production from oil palm fronds by 68-132%, but none of the fungi improved the in vitro rumen fermentability of maize stover. C. subvermispora and L. edodes increased total gas production of sugarcane bagasse by 65-71%, but P. eryngii and P. ostreatus decreased it by 22-50%. There was a linear relationship (P<0.05) between the proportion of lignin in the original substrate and the increase in in vitro gas production observed for C. subvermispora and L. edodes treatments (R2=0.92 and 0.96, respectively). It is concluded that C. subvermispora and L. edodes have a particularly high potential to improve the nutritive value of highly lignified ruminant feeds.
玉米秸秆、水稻秸秆、油棕叶和甘蔗渣在 24°C 下用白腐真菌糙皮侧耳、香菇、鲍鱼菇或糙皮侧耳处理 0-6 周。真菌使油棕叶的总气体产量增加了 68-132%，但没有一种真菌能改善玉米秸秆的体外瘤胃发酵能力。糙皮侧耳和香菇使甘蔗渣的总气体产量增加了 65-71%，但鲍鱼菇和糙皮侧耳使总气体产量降低了 22-50%。在体外气体产生的观察中，原始基质中木质素的比例与糙皮侧耳和香菇处理的增加之间存在线性关系（P<0.05）（R2 分别为 0.92 和 0.96）。结论是，糙皮侧耳和香菇具有特别高的潜力来提高高度木质化反刍动物饲料的营养价值。
