Activity And Diversity Of Sulfate- and Methane-based Pathways Of Anaerobic Chitin And N-acetylglucosamine Degradation In Marine Sediments
[American Society of Microbiology] Sulfate reduction is estimated to account for half of the organic carbon respiration in anoxic, organic-rich ocean sediments. Sulfate-reducing microorganisms (SRMs) typically oxidize simple carbon compounds, […]
