Based on continuous anaerobic co-digestion of cow manure with available carbon slowly released corn straw, the effect of adding available carbon quickly released fruit and vegetable waste (FVW) was explored, meanwhile microbial community variation was studied in this study. When the FVW added was 5% and 1%, the methane production of the cow manure and corn straw was improved, and the start-up process was shortened. With higher proportion of FVW to 5%, the performance was superior with a mean methane yield increase of 22.4%, and a greater variation of bacterial communities was observed. FVW enhanced the variation of the bacterial communities. The microbial community structure changed during fermentation and showed a trend toward a diverse and balance system. Therefore, the available carbon quickly released FVW was helpful to improve the anaerobic co-digestion of the cow manure and available carbon slowly released corn straw.
本研究通过连续厌氧共消化牛粪与缓慢释放有效碳源的玉米秸秆，探讨了快速释放有效碳源的果蔬废物（FVW）的添加效果，同时研究了微生物群落的变化。当添加的 FVW 分别为 5%和 1%时，可提高牛粪和玉米秸秆的甲烷产量，缩短启动过程。当 FVW 的比例提高到 5%时，性能更优，平均甲烷产量增加 22.4%，且细菌群落的变化更大。FVW 增强了细菌群落的变化。微生物群落结构在发酵过程中发生变化，呈现出多样化和平衡的系统趋势。因此，快速释放有效碳源的 FVW 有助于提高牛粪与缓慢释放有效碳源的玉米秸秆的厌氧共消化。
