Gases like H2, N2, CO2, and CO are increasingly recognized as critical feedstock in “green”
energy conversion and as sources of nitrogen and carbon for the agricultural and chemical …

Due to their substantial volume, subsoils contain more of the total soil carbon (C) pool than
topsoils. Much of this C is thousands of years old, suggesting that subsoils offer …

Biohydrogen is a green and eco-friendly energy carrier with the potential to reduce our
dependency on fossil fuels. Renewable biohydrogen production from waste biomass …

Biohydrogen is a clean and renewable source of energy. It can be produced by using
technologies such as thermochemical, electrolysis, photoelectrochemical and biological, etc …

While hydrogen plays an ever-increasing role in modern society, nature has utilized
hydrogen since a very long time as an energy carrier and storage molecule. Among the …

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 …

Soils contain a tangle of minerals, water, nutrients, gases, plant roots, decaying organic
matter, and microorganisms which work together to cycle nutrients and support terrestrial …

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 …

Nitrite-oxidizing bacteria (NOB) catalyze the second step of nitrification, nitrite oxidation to
nitrate, which is an important process of the biogeochemical nitrogen cycle. NOB were …

Ammonia oxidising archaea are among the most abundant living organisms on Earth and
key microbial players in the global nitrogen cycle. They carry out oxidation of ammonia to …
