Net-zero emission and self-sustaining carbon-neutral have been widely encouraged and
intensively explored in wastewater treatment, as the wastewater industry accounts for …

Raman microspectroscopy offers microbiologists a rapid and non-destructive technique to
assess the chemical composition of individual live microorganisms in near real time. In this …

Nitrification, the oxidation of ammonia (NH3) via nitrite (NO2−) to nitrate (NO3−), is a key
process of the biogeochemical nitrogen cycle. For decades, ammonia and nitrite oxidation …

The function of cells in their native habitat often cannot be reliably predicted from genomic
data or from physiology studies of isolates. Traditional experimental approaches to study the …

Oxidation of ammonia to nitrite by bacteria and archaea is responsible for global emissions
of nitrous oxide directly and indirectly through provision of nitrite and, after further oxidation …

Highlights•Nitrification causes nitrogen losses with impact on crop yield and
environment.•Newly discovered microbes can be important for nitrification in agricultural …

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 …

The continuous increase of the greenhouse gas nitrous oxide (N2O) in the atmosphere due
to increasing anthropogenic nitrogen input in agriculture has become a global concern. In …

Nitrogen fertilisation of agricultural soil contributes significantly to emissions of the potent
greenhouse gas nitrous oxide (N2O), which is generated during denitrification and, in oxic …

Chemolithotrophic ammonia-oxidizing bacteria and Thaumarchaeota are central players in
the global nitrogen cycle. Obligate ammonia chemolithotrophy has been characterized for …
