Public Description

Northern terrestrial environments are large stores of organic carbon accounting for one third of global soil carbon pool. The fate of this C is of increasing interest due to global warming. Predicting processes of the global carbon cycle requires a detailed understanding of the functional activities of the soil microbiota and how they impact the biogeochemical processes of their ecosystem. Acidobacteria are among the most dominating bacterial phyla in tundra soils but although ubiquitous, their functions are poorly understood. In this study we integrate field and laboratory experiments to elucidate the ecological role of Acidobacteria in soil organic matter degradation in tundra ecosystems. The ultimate goal is a systems- and ecosystem-level understanding of the metabolic networks of Acidobacteria and other species consortia involved in biogeochemical cycling of carbon. This study will contribute to our fundamental understanding of microbial activity and carbon cycling mechanisms.
