Hazardous gases sustain microbes underfoot

Nature Microbiology volume 6, pages 145–146 (2021)Cite this article

Subjects

Most soil microorganisms can use the trace gases carbon monoxide, hydrogen and methane — and potentially other inorganic compounds — to supplement their cellular energetic needs.

Soil microbiomes are the most diverse biological assemblages on Earth. These tiny lives mediate processes critical to humanity, including the regulation of global climate and the maintenance of soil and plant health. Although soils are among the longest-studied microbial habitats, most soil microbial diversity remains undescribed because of the challenges associated with isolating soil microorganisms in the laboratory1. Only recently has it been possible to quantify the magnitude of the metabolic versatility found in soil microbiomes due to improvements in DNA sequencing and computational technology2. In this issue of Nature Microbiology, Bay et al. show that soils contain abundant microorganisms that have the unexpected ability to derive energy from gases that are hazardous to humans3.
