How do methanotrophs handle the toxic effects of hydrogen sulfide?

January 10, 2023

Methanotrophs—organisms that grow by consuming methane—seem to be perfect for alleviating global warming, since methane accounts for about 30% of this effect. However, drilling sites, where the natural gas is mostly composed of methane, also contains hydrogen sulfide (H2S), which inhibits the growth of methanotrophs. In a new study, researchers have discovered that the methanotroph Methylococcus capsulatus Bath has an enzyme that helps it grow in the presence of small amounts of H2S.
