Project description:This study investigates temporal dynamics in microbial community function within the freshwater ecosystem of Lake Zurich, Switzerland, over three months (36 timepoints). Metagenome-assembled genomes (MAGs) and metaproteomes were analyzed to identify species-specific and community-level protein expression patterns. The study explores how bacterial species contribute to ecosystem functioning through protein-level activity, focusing on relationships between species taxonomy, abundance, and protein investment patterns.
Project description:Anaerobic methanotrophic archaea are key components of the biological methane filter, but progress in understanding their physiology has been limited by the lack of axenic cultures. This study establishes near-axenic electrode-grown cultures of a freshwater anaerobic methanotroph, proposed as Candidatus Methanoperedens vercellensis, and characterizes its physiology, genome, electron transfer properties, and proteins using shotgun proteomics.
