The atmosphere has recently been recognized as a major source of energy sustaining life.
Diverse aerobic bacteria oxidize the three most abundant reduced trace gases in the …

Abstract The [FeFe]-and [NiFe]-hydrogenases catalyze the formal interconversion between
hydrogen and protons and electrons, possess characteristic non-protein ligands at their …

Numerous diverse microorganisms reside in the cold desert soils of continental Antarctica,
though we lack a holistic understanding of the metabolic processes that sustain them. Here …

Recent physiological and ecological studies have challenged the long-held belief that
microbial metabolism of molecular hydrogen (H2) is a niche process. To gain a broader …

H2 metabolism is proposed to be the most ancient and diverse mechanism of energy-
conservation. The metalloenzymes mediating this metabolism, hydrogenases, are encoded …

Soil microorganisms globally are thought to be sustained primarily by organic carbon
sources. Certain bacteria also consume inorganic energy sources such as trace gases, but …

Diverse aerobic bacteria use atmospheric H2 as an energy source for growth and survival.
This globally significant process regulates the composition of the atmosphere, enhances soil …

Molecular hydrogen (H2) is an abundant and readily accessible energy source in marine
systems, but it remains unknown whether marine microbial communities consume this gas …

Carbon monoxide (CO) is a ubiquitous atmospheric trace gas produced by natural and
anthropogenic sources. Some aerobic bacteria can oxidize atmospheric CO and …

The global atmospheric level of methane (CH4), the second most important greenhouse
gas, is currently increasing by∼ 10 million tons per year. Microbial oxidation in unsaturated …
