Thermotolerant cellulolytic consortium for improvement biogas production from oil palm empty fruit bunches (EFB) by prehydrolysis and bioaugmentation strategies was investigated via solid-state anaerobic digestion (SS-AD). The prehydrolysis EFB with Clostridiaceae and Lachnospiraceae rich consortium have maximum methane yield of 252 and 349 ml CH g VS with total EFB degradation efficiency of 62% and 86%, respectively. Clostridiaceae and Lachnospiraceae rich consortium augmentation in biogas reactor have maximum methane yield of 217 and 85.2 ml CH g VS with degradation efficiency of 42% and 16%, respectively. The best improvement of biogas production was achieved by prehydrolysis EFB with Lachnospiraceae rich consortium with maximum methane production of 113 m CH tonne EFB. While, Clostridiaceae rich consortium was suitable for augmentation in biogas reactor with maximum methane production of 70.6 m CH tonne EFB. Application of thermotolerant cellulolytic consortium into the SS-AD systems could enhance biogas production of 3-11 times.
通过固态厌氧消化（SS-AD）研究了耐热纤维素分解菌共生体，以提高通过预水解和生物增强策略从油棕空果串（EFB）生产沼气。富含梭菌科和lachnospiraceae 的预水解 EFB 具有最大的甲烷产量为 252 和 349ml CH g VS，总 EFB 降解效率分别为 62%和 86%。沼气反应器中梭菌科和lachnospiraceae 丰富的共生体的添加，最大甲烷产量为 217 和 85.2ml CH g VS，降解效率分别为 42%和 16%。通过富含lachnospiraceae 的预水解 EFB 实现了最佳的沼气生产改进，最大甲烷产量为 113m CH 吨 EFB。而富含梭菌科的共生体则适合在沼气反应器中添加，最大甲烷产量为 70.6m CH 吨 EFB。耐热纤维素分解菌共生体在 SS-AD 系统中的应用可以将沼气产量提高 3-11 倍。
