Project description:Large amounts of carbon sequestered in permafrost are becoming available for microbial degradation. We investigated 1,529 microbial metagenome-assembled genomes recovered from our site to understand carbon processing in this environment. Metabolic reconstruction, supported by metatranscriptomic and metaproteomic data, revealed key populations involved in organic matter degradation, including bacteria encoding a pathway for xylose degradation only previously identified in fungi.
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.
