Production of bio-sulfide by sulfate-reducing bacteria (SRB) is low in operational cost and can be achieved by applying sulfate-reducing activated sludge to the wastewater streams. High levels of sulfate ions in the SMD are essential for SRB growth (Wu et al., 2011). The mechanisms involved in Sb(V) removal from water by SRB has been rarely reported.
