| 摘 要： | 为促进微生物预处理方法在提高玉米秸秆高效厌氧消化产甲烷方面的应用效果,该文研究了由黑曲霉(Aspergillus)、木霉(Trichoderma)、草酸青霉(Penicillium)和白腐真菌组成的复合微生物菌系HK-4,对玉米秸秆预处理及厌氧消化产气性能的影响。将复合微生物菌系加入到粒径为0.7~1 cm玉米秸秆中,在28℃恒温条件下190 r/min震荡培养15 d,测得纤维素、半纤维素和木质素的降解率分别可达64.52%、51.06%和3.89%。使用经HK-4处理过的玉米秸秆,用于沼气生产,发酵32 d,复合微生物菌系组共产生7364 m L气体,比未处理组提高了27.4%;预处理4 d,复合微生物处理组甲烷体积分数即可提升到40%以上,之后20 d在45%~53%之间波动,而未经HK-4处理过的玉米秸秆,甲烷体积分数在第6天才稳定到36.7%。
