Nanofibrils other colloidal biopolymers binding trace elements in coastal seawater:Significance variations in element
2014/4/16
Colloidal size spectra of Fe, Cu, Ag, La, and Pb were determined by asymmetrical flow field–flow fractionation coupled to high-resolution inductively coupled plasma mass spectrometry, in samples from ...
Production of cobalt binding ligands in a Synechococcus feature at the Costa Rica upwelling dome
cobalt binding ligands Synechococcus feature Costa Rica upwelling dome
2014/5/8
The Costa Rica upwelling dome (CRD; ~8.67°N and 90.6°W) was characterized chemically for cobalt and nickel abundances and speciation and biologically using cyanobacterial abundances and phylogeny. Tot...
Novel copper-binding and nitrogen-rich thiols produced and exuded by Emiliania huxleyi
Novel copper-binding nitrogen-rich thiols produced
2014/5/19
In surface seawater, dissolved copper (Cu) is predominantly bound by a small pool of strong ligands, with further
complexation by a larger pool of weaker ligands. Although the chemical structure of b...

Photochemical reactivity of siderophores produced by marine heterotrophic bacteria and cyanobacteria, based on characteristic Fe(III) binding groups
Photochemical reactivity siderophores produced marine heterotrophic bacteria cyanobacteria Fe(III) binding groups
2014/5/20
Siderophores, high-affinity Fe(III) ligands produced by microorganisms to facilitate iron acquisition, might contribute significantly to dissolved Fe(III) complexation in ocean surface waters. In prev...
