Does functional redundancy always rule anaerobic digestion communities?

摘要：

　　Microorganisms play a critical role in a biogas-producing system (BPS).Many BPSs have a microbiota consisting balanced proportions of archaea and bacteria.However,little is known about how it contributes to stability,resilience,and robustness of BPSs.Here we document a systematic study of the microbiota-functionality nexus based on 138 samples out of twenty well-profiled lab-scale BPSs in four major configurations running for up to two years.Our result reveals that the BPSs communities are neither functionally plastic nor functionally redundant.In other words,a high variety in communities usually exhibits a strong difference in performances.The understandings of the role of functional redundancy will benefit valuable considerations for a proactive management of BPSs in the future.
