Identification of bacteria involved in non-sulfate based hydrogen sulfide production in an aquaculture environment

The paper identifies bacteria involved in non-sulfate-based hydrogen sulfide production in aquaculture systems and compares their activity with sulfate-reducing bacteria.

Anaerobic oxidation of methane in sediments of a nitrate-rich, oligo-mesotrophic boreal lake

This study investigates anaerobic methane oxidation in lake sediments, finding that nitrate does not enhance AOM rates, while other electron acceptors like iron and sulfate may play a role.

Novel autotrophic organisms contribute significantly to the internal carbon cycling potential of a boreal lake

The paper shows that autotrophic carbon fixation and internal carbon cycling are significant in a boreal lake, even below the euphotic zone, driven by chemolithotrophic organisms.
