Abstract
Root exudates from Tephrosia plants contained a rock-iron [Fe(OH3] -solubilizing compound. This was purified to apparent homogeneity and appears to possess an iron-binding phenolic moiety linked to a proteinaceous component that may act as a receptor. The lyophilized purified fraction showed maximum Fe(OH)3-solubilizing activity at 50°C under acidic pH. Its activity was influenced by trace ions (Co, Cu, Zn, B, Mo, Mn) and toxic metal ions (Ni, Al, Pb, Cr, Hg), but ions such as Na, K, Mg, and Ca had no significant effects on its Fe(OH)3-solubilizing activity.
