Copper‐dependent iron transport in coastal and oceanic diatoms (2006, background): “In turn, phytoplankton are known to influence the speciation of dissolved Cu in seawater by releasing strong Cu organic ligands in response to Cu toxicity (Moffett and Brand 1996; Croot et al. 2000; Vasconcelos and Leal 2001).”
Metallophores and Trace Metal Biogeochemistry (2015, background): “Rather, previous research consistently has found Cu to be bound in stable organic complexes, except in highly Cu-polluted waters (Croot et al. 2000; Leal et al. 1999; Moffett and Brand 1996; Town and Filella 2000; Xue et al. 1996; Xue and Sigg 1999).”
The effect of Fe and Cu on growth and domoic acid production by Pseudo-nitzschia multiseries and Pseudo‐nitzschia australis (2002, background): “Other diatoms also release Cu-complexing ligands under stress conditions, generating dissolved ligand concentrations similar to the DA-E release measured here (McKnight and Morel 1979; Croot et al. 2000).”
Domoic acid: The synergy of iron, copper, and the toxicity of diatoms (2005, background): “Other marine eukaryotic phytoplankton have been shown to release copper complexing ligands having similar conditional constants for copper (Croot et al. 2000), but, as for Synechococcus, this release has been only suggested to decrease copper toxicity.”
Plankton copper requirements and uptake in the subarctic Northeast Pacific Ocean (2009, background): “These synthetic ligands likely differ significantly from natural Cu complexing ligands, which are hypothesized to contain S and N donor groups (Leal and van den Berg, 1998; Croot et al., 2000; Laglera and van den Berg, 2003; Dupont et al., 2006; Wiramanaden, 2007), with varying conditional stability”
Production of a molybdophore during metal-targeted dissolution of silicates by soil bacteria (2005, background): “Others have suggested that Cu-complexing compounds may be secreted by some organisms as a detoxification mechanism (Croot et al., 2000; Moffett and Brand, 1996).”
