Methanomethylovorans

Methanomethylovorans is a genus of bacteria in the family Methanomethylovoraceae. It is a type of methanogen, which are microorganisms that produce methane as a metabolic byproduct in anoxic conditions. Methanomethylovorans are known for their ability to utilize methylated compounds, such as methylamines and methanol, as a source of carbon and energy.

Taxonomy

The genus Methanomethylovorans was first described in 2000 by Lomans et al. The type species is Methanomethylovorans hollandica, which was isolated from freshwater sediment in the Netherlands. Other species in this genus include Methanomethylovorans thermophila and Methanomethylovorans uponensis.

Metabolism

Methanomethylovorans are anaerobic organisms that can use a variety of one-carbon compounds, including methanol and methylamines, as substrates for methanogenesis. They are also capable of using carbon dioxide and hydrogen as substrates. The metabolism of Methanomethylovorans is unique among methanogens in that they can use both methylated compounds and carbon dioxide/hydrogen for growth.

Ecology

Methanomethylovorans are found in a variety of environments, including freshwater and marine sediments, peat bogs, and the gastrointestinal tract of animals. They play a significant role in the global carbon cycle by converting methylated compounds and carbon dioxide into methane, a potent greenhouse gas.

Health implications

While Methanomethylovorans are not typically pathogenic, they can be found in the human gut where they contribute to the production of methane. This can be problematic in individuals with irritable bowel syndrome (IBS), as excessive methane production has been linked to constipation and other IBS symptoms.
