The ocean is home to a diverse and metabolically versatile microbial community that
performs the complex biochemical transformations that drive the nitrogen cycle, including …

Nitrogen is an essential component of all living organisms and the main nutrient limiting life
on our planet. By far, the largest inventory of freely accessible nitrogen is atmospheric …

Nitrification, the oxidation of ammonia to nitrate, is an essential process in the
biogeochemical nitrogen cycle. The first step of nitrification, ammonia oxidation, is performed …

The deep sea, the largest ocean's compartment, drives planetary-scale biogeochemical
cycling. Yet, the functional exploration of its microbial communities lags far behind other …

Biotic and abiotic surfaces in marine waters are rapidly colonized by microorganisms.
Surface colonization and subsequent biofilm formation and development provide numerous …

Aerobic ammonium oxidizing bacteria were first isolated more than 100 years ago and
hydroxylamine is known to be an intermediate. The enzymatic steps involving …

Microorganisms are major drivers of elemental cycling in the biosphere. Determining the
abundance of microbial functional traits involved in the transformation of nutrients, including …

Glycerol dialkyl glycerol tetraether (GDGT) lipids are membrane lipids which were long
thought to be synthesized mainly by archaea, organisms thought to be limited to extreme …

Marine bacteria and archaea play key roles in global biogeochemistry. To improve our
understanding of this complex microbiome, we employed single-cell genomics and a …

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 …
