DOI: 10.1002/lno.11779
Abstract: Bacterial sulfate reduction (SR) is often determined by radiotracer techniques using 35S‐labeled sulfate. In environments featuring simultaneous sulfide oxidation, SR can be underestimated due to re‐oxidation of 35S‐sulfide. Recycling of 35S‐tracer is expected to be… read more here.

DOI: 10.1016/j.gca.2019.12.033
Abstract: Abstract Arctic fjord sediments of Svalbard receive terrestrial material from glacial runoff and organic matter from marine primary productivity. Organic carbon mineralization proceeds primarily through sulfate and iron reduction in the fjord sediment. The ongoing… read more here.

DOI: 10.1021/acschembio.8b00258
Abstract: The mitochondrial sulfide oxidation pathway prevents the toxic accumulation of hydrogen sulfide (H2S), a signaling molecule that is maintained at low steady-state concentrations. Sulfide quinone oxidoreductase (SQR), an inner mitochondrial membrane-anchored protein, catalyzes the first… read more here.
