One-quarter of photosynthesis-derived carbon on Earth rapidly cycles through a set of short-
lived seawater metabolites that are generated from the activities of marine phytoplankton …

Nitrogen (N) is one of the primary nutrients required to build biomass and is therefore in high
demand in aquatic ecosystems. Estuaries, however, are frequently inundated with high …

Dissolved organic matter (DOM) in the oceans is one of the largest pools of reduced carbon
on Earth, comparable in size to the atmospheric CO2 reservoir. A vast number of …

Microalgae of different evolutionary origins are typically found in rivers, lakes, and oceans,
providing more than 45% of global primary production. They provide not only a food source …

We investigated changes in quality and quantity of extracellular and biomass‐derived
organic matter (OM) from three axenic algae (genera Rhodomonas, Chlamydomonas …

Ammonia-oxidizing archaea (AOA) and bacteria (AOB), nitrite-oxidizing bacteria (NOB), and
complete ammonia oxidizers (comammox) are responsible for nitrification in nature; …

Mid-summer peaks in the abundance of Thaumarchaeota and nitrite concentration observed
on the Georgia, USA, coast could result from in situ activity or advection of populations from …

In the ocean surface layer and cell culture, the polyamine transport protein PotD of SAR11
bacteria is often one of the most abundant proteins detected. Polyamines are organic …

Dissolved organic nitrogen (DON) can account for a large fraction of the dissolved nitrogen
(N) pool in the ocean, but the cycling of marine DON is poorly understood. Recent …

Polyamines are a series of short-chain aliphatic amines which can be produced during the
metabolism of cells, and are widely distributed in aquatic organisms. Polyamines are …
