Extracellular production of superoxide by marine diatoms: Contrasting effects on iron redox chemistry and bioavailability
Extracellular production of superoxide marine diatoms Contrasting effects iron redox chemistry and bioavailability
2014/5/9
We report the extracellular production of superoxide in cultures of the marine diatoms Thalassiosira weissflogii and Thalassiosira pseudonana. In EDTA-buffered media with ~45 pmol L-1 iron (Fe)(III)',...
A role for manganese in superoxide dismutases and growth of iron-deficient diatoms
superoxide dismutases iron-defi cient diatoms
2014/5/19
We have discovered that coastal and oceanic diatoms require more manganese (Mn) to grow in iron (Fe) -deficient
than in Fe-sufficient seawater. At low inorganic concentrations, like those...
