A role for manganese in superoxide dismutases and growth of iron-deficient diatoms
superoxide dismutases iron-defi cient diatoms
font style='font-size:12px;'>
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...
