Abstract
The project focuses on a poorly known carbon-sequestering environmental process by a group of diverse bacteria forming intracellular carbonates, occurring at oxic/anoxic boundaries (OAB) in aquatic environments. The molecular and geochemical processes of bacterial biomineralization will be studied by a combination of approaches in isotope and aqueous geochemistry, mineralogy, genomics and microbial ecology, from the single cell to the community level and from the natural environment to the lab. Together, CarboMagnet deliverables will provide new microbial models for efficient inorganic carbon/alkaline earth elements (AEE) sequestration and decipher the contribution of this reservoir to the global cycling of C and AEE.
