Microbial players in the biogeochemistry of methane in fiberbanks
Fiberbanks have recently received attention as potential greenhouse gas (GHG) sources in Sweden. Fiberbanks are anthropogenically caused fibre-rich sediments in aquatic environments formed by unregulated discharge of fibrous wastewater from historical pulp and paper industries. A majority of fiberbanks show signs of gas ebullition, mainly consisting of methane and carbon dioxide, resulting from an
