为了对秸秆类原料进行厌氧消化制取甲烷,提高底物利用率和甲烷产量,该研究以玉米秸秆为原料,以取自不同环境中的7个样品为接种物,35℃,对玉米秸秆进行厌氧消化,研究其甲烷产量、甲烷产率及发酵时间等。研究结果证明:筛选得到3个转化玉米秸秆并产甲烷的优势菌群,其最高容积甲烷产率分别为0.66、0.62、0.73m~3/m~3·d,底物产甲烷量分别为403、397、410L/kgvs,明显高于报道过的相应数据。该研究为玉米秸秆的高效制取甲烷提供了优势的微生物菌群基础。
In order to anaerobic digestion of straw raw materials to make methane, improve substrate utilization and methane production, the study of corn stalks as raw materials, taken from 7 different samples in different environments as inoculum, 35 ℃, corn stover Anaerobic digestion, research methane production, methane production and fermentation time. The results showed that the three dominant microbial communities that transformed corn stalks and produced methane were obtained. The highest methane yield was 0.66, 0.62 and 0.73m ~ 3 / m ~ 3 · d respectively, and the yield of methane was 403, 397,410 L / kg vs, significantly higher than the corresponding data reported. This study provides the basis for microbial community with superiority for the efficient preparation of methane from corn stover.
