WebNov 1, 2024 · Methanogens inhabit sulfidic environments where transition metals (e.g., Fe, Ni, Co, and Mo) predominantly exist as aqueous metal sulfide and/or minerals, and these are likely the preferred form of these elements over dissolved, ionic counterparts. This is perhaps due to the limited solubility of metal sulfides that, in turn, keeps aqueous ... WebApr 4, 2024 · While there is some evidence from carbon isotope data that sources of methane as ancient as 3.5 billion years old may have been biological in origin, until now there has been no solid evidence that methane-producing microbes existed early enough in Earth’s history to be responsible for keeping the early Earth warmed up.
