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 nutrient for marine phytoplankton and indeed all life forms.
Current data show that P availability is growth‐limiting in certain marine systems and can …

Although prokaryotes are small in size, they are a significant biomass component in aquatic
planktonic ecosystems and play a major role in biogeochemical processes. A review of the …

Phosphate addition to surface waters of the ultraoligotrophic, phosphorus-starved eastern
Mediterranean in a Lagrangian experiment caused unexpected ecosystem responses. The …

Exploring the role of enzymes in biogeochemical processes, this reference explores the
function, molecular biology, and biochemistry of microorganisms and their intra-and extra …

Phosphatase is a key-enzyme in the marine environment, although life in the sea is normally
not P limited. Expression of phosphatase in algae is generally regulated by the prevailing …

The eastern Mediterranean has a high nitrate to phosphate (N: P) ratio (~ 28: 1) in the deep
water and a highly unusual P limitation of the primary productivity. We present a detailed …

Metagenomic analyses have revealed widespread and diverse retinal-binding rhodopsin
proteins (named proteorhodopsins) among numerous marine bacteria and archaea, which …

Estimates of the sources and wet deposition fluxes of inorganic nutrients (PO43−, NO3−,
NO2−, NH4+) have been made using a long‐term wet atmospheric deposition measurement …

Even though it is widely accepted that bacterioplankton growth in lakes and marine
ecosystems is determined by the trophic status of the systems, knowledge of the relationship …
