Microbial cells (ie, bacteria, archaea, microeukaryotes) in oceans secrete a diverse array of
large molecules, collectively called extracellular polymeric substances (EPSs) or simply …

Phosphorus (P) is an essential element to all life, being a structural and functional
component of all organisms. 1-4 P provides the phosphate-ester backbone of DNA and …

Coral reefs are the most biodiverse of all marine ecosystems; however, very little is known
about prokaryotic diversity in these systems. To address this issue, we sequenced over 1000 …

Few of us may ever live on the sea or under it, but all of us are making increasing use of it
either as a source of food and other materials, or as a dump. As our demands upon the …

The oxic realms of freshwater and marine environments are zones of high prokaryotic
mortality. Lysis by viruses and predation by ciliated and flagellated protists result in the …

The growth potential of cyanobacteria is impressive. Under ideal circumstances,
cyanobacteria typically double once or twice per day. In 40 days, a single cyanobacterium …

Lack of carbon has been assumed to be the most common limiting factor for bacterial growth
in soil, although there are reports of limitation by other nutrients, eg nitrogen and …

The results of empirical studies have revealed links between phytoplankton and
bacterioplankton, such as the frequent correlation between chlorophyll a and bulk bacterial …

Measures to reduce eutrophication have often led to a more effective decline of phosphorus
(P) than nitrogen (N) concentrations. The resultant changes in riverine nutrient loads can …

Phosphate is an important nutrient that restricts microbial production in many freshwater,,
and marine environments,,. The actual concentration of phosphate in phosphorus-limited …
