Project description:Anaerobic digestion is a popular and effective microbial process for waste treatment. The performance of anaerobic digestion processes is contingent on the balance of the microbial food web in utilizing various substrates. Recently, co-digestion, i.e., supplementing the primary substrate with an organic-rich co-substrate has been exploited to improve waste treatment efficiency. Yet the potential effects of elevated organic loading on microbial functional gene community remains elusive. In this study, functional gene array (GeoChip 5.0) was used to assess the response of microbial community to the addition of poultry waste in anaerobic digesters treating dairy manure. Consistent with 16S rRNA gene sequences data, GeoChip data showed that microbial community compositions were significantly shifted in favor of copiotrophic populations by co-digestion, as taxa with higher rRNA gene copy number such as Bacilli were enriched. The acetoclastic methanogen Methanosarcina was also enriched, while Methanosaeta was unaltered but more abundant than Methanosarcina throughout the study period. The microbial functional diversity involved in anaerobic digestion were also increased under co-digestion.

Project description:In anaerobic digestion plants (ADP) homogenization of the feed, the fermenter content and the microbial communities represents a precondition for effective and robust biogas production,but also a major energy consumer. For a 850 m3 agricultural AD-P equipped with eight sampling ports we investigated whether different feeding and stirring regimes enable a sufficient homogenization of the microbial communities using metaproteome and TRFLP analysis. Systematic comparison of the samples by scatter plots and students t-test revealed only a limited number of slightly changed metaproteins, taxonomies and biological processes, indicating no systematic differences between the microbial communities in center and rim as well as between top and bottom. However, comparison of the amount of shared identified metaproteins between the sample ports showed minor variation, which might be correlated with the applied stirring strategy. In sum, the applied stirring and feeding conditionswere sufficient to homogenize the microbial communities in AD-Ps largely.
