Using an interdisciplinary approach, this paper reviews current knowledge in the field of
natural hydrogen. For the first time, it combines perspectives on hydrogen from the literature …

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 …

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 …

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 …

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 …

Cultivation-independent surveys have shown that the desert soils of Antarctica harbour
surprisingly rich microbial communities,,. Given that phototroph abundance varies across …

Microbial functioning refers to microbial activity because only the active microorganisms
drive biogeochemical processes. Despite the importance of active microorganisms, most …

Members of the phylum Acidobacteria are abundant and ubiquitous across soils. We
performed a large‐scale comparative genome analysis spanning subdivisions 1, 3, 4, 6, 8 …
