Fig. 7

Graphical representation of tentative schematic mechanism of arsenic mobilization by Staphylococcus sp. TA6. The process can be catagorised in four sequential steps (A) production of siderophore to scavenge iron from arsenopyrite ores (B) Entry of arsenate through pit/pst phosphate transport channel into the cell (C) conversion of arsenate to arsenite and (D) efflux of arsenite to the surrounding environment.
