To improve biomass digestion while ensuring overall process stability, microbiome-based management strategies become more important. In this study, metagenomes and metaproteomes were used for metagenomically assembled genome (MAG)-centric analyses to investigate a full-scale biogas plant consisting of three differentially operated digesters. Microbial communities were analyzed regarding their taxonomic composition, functional potential, as well as functions expressed on the proteome level. Different abundances of genes and enzymes related to the biogas process could be mostly attributed to different process parameters. Individual MAGs exhibiting different abundances in the digesters were studied in detail, and their roles in the hydrolysis, acidogenesis and acetogenesis steps of anaerobic digestion could be assigned. Methanoculleus thermohydrogenotrophicum was an active hydrogenotrophic methanogen in all three digesters, whereas Methanothermobacter wolfeii was more prevalent at higher process temperatures. Further analysis focused on MAGs, which were abundant in all digesters, indicating their potential to ensure biogas process stability. The most prevalent MAG belonged to the class Limnochordia; this MAG was ubiquitous in all three digesters and exhibited activity in numerous pathways related to different steps of AD. dc:creator: Julia Hassa, Tom Jonas Tubbesing, Irena Maus, Robert Heyer, Dirk Benndorf, Mathias Effenberger, Christian Henke, Benedikt Osterholz, Michael Beckstette, Alfred Pühler, Alexander Sczyrba and Andreas Schlüter dcterms:created: 2023-09-27T09:30:09Z Last-Modified: 2023-09-27T09:33:13Z dcterms:modified: 2023-09-27T09:33:13Z dc:format: application/pdf; version=1.7 title: Uncovering Microbiome Adaptations in a Full-Scale Biogas Plant: Insights from MAG-Centric Metagenomics and Metaproteomics Last-Save-Date: 2023-09-27T09:33:13Z pdf:docinfo:creator_tool: LaTeX with hyperref access_permission:fill_in_form: true pdf:docinfo:keywords: biogas microbiome; biogas process chain; anaerobic digestion; metagenomic binning; metagenome analyses; metaproteome analyses pdf:docinfo:modified: 2023-09-27T09:33:13Z meta:save-date: 2023-09-27T09:33:13Z pdf:encrypted: false dc:title: Uncovering Microbiome Adaptations in a Full-Scale Biogas Plant: Insights from MAG-Centric Metagenomics and Metaproteomics modified: 2023-09-27T09:33:13Z cp:subject: The current focus on renewable energy in global policy highlights the importance of methane production from biomass through anaerobic digestion (AD).
