Web10 jul. 2024 · Recently, a study published in Natural Climate Change has discovered high-affinity methanotrophs (HAMs, otherwise known as methane-oxidising bacteria), in Arctic mineral soils. More specifically, methanotrophs are a unique type of bacteria capable of using methane as their only source of energy. Webdigesting bacteria. 3. The following step is named the acetogenic phase, because the acetogenic bacteria are mainly building acetic acid from the previously built organic acids and alcohols. 4. This acetic acid and to a small extent also H 2 and CO 2 are converted in the fourth step, the methanogenic phase, of the methane-forming bacteria to CH 4.
