我们研究了短期动态的微生物组成和功能的生物反应器与接种物收集全规模和实验室为基础的厌氧消化（AD）系统。两种接种物的Bray-Curtis差异约为预测的京都基因和基因组百科全书途径的10%和分类组成的40%，但在甲烷生产中产生相似的性能，这意味着群落组成的变化可能与性能无关。然而，挥发性脂肪酸与分类变异的显著相关性表明，AD的途径可能是不同的，因为不同的属。预测功能的显着变化的属主要与发酵，这加强了结论，大多数微生物的变化发生在发酵物种，并导致替代路线，导致类似的甲烷生产产甲烷生物反应器。这一发现揭示了一些光AD社区的调节，这取决于目标，以恢复中间体或甲烷的理解。发酵中间产物对AD途径的影响大于对AD性能的影响发酵菌种的冗余导致了独立的群落变异生物科学;生物量;生物技术;化学工程;微生物学;
We investigated the short-term dynamics of microbial composition and function in bioreactors with inocula collected from full-scale and laboratory-based anaerobic digestion (AD) systems. The Bray-Curtis dissimilarity of both inocula was approximately 10% of the predicted Kyoto Encyclopedia of Genes and Genomes pathway and 40% of the taxonomic composition and yet resulted in a similar performance in methane production, implying that the variation of community composition may be decoupled from performance. However, the significant correlation of volatile fatty acids with taxonomic variation suggested that the pathways of AD could be different because of the varying genus. The predicted function of the significantly varying genus was mostly related to fermentation, which strengthened the conclusion that most microbial variation occurred within the fermentative species and led to alternative routes to result in similar methane production in methanogenic bioreactors. This finding sheds some light on the understanding of AD community regulation, which depends on the aims to recover intermediates or methane. The variation of the community was decoupled from AD performance The fermentative intermediates affect AD pathway rather than the AD performance The redundancy of fermentative species induces the independent community variation Biological sciences; Biomass; Biotechnology; Chemical engineering; Microbiology;
