Cryptic CH4 cycling in the sulfate–methane transition of marine sediments apparently mediated by ANME-1 archaea
Methane in the seabed is mostly oxidized to CO2 with sulfate as the oxidant before it
reaches the overlying water column. This microbial oxidation takes place within the sulfate …

Environmental evidence for net methane production and oxidation in putative ANaerobic MEthanotrophic (ANME) archaea
Summary Uncultured ANaerobic MEthanotrophic (ANME) archaea are often assumed to be
obligate methanotrophs that are incapable of net methanogenesis, and are therefore used …
