Lead biosorption by different morphologies of fungus Mucor indicus

► Biosorption characteristics of different morphologies were investigated. ► Filamentous form of Mucor indicus showed the maximum biosorption capacity. ► Ho's pseudo-second-order model properly described the biosorption kinetics. ► Investigation of 5 different variables on biosorption characteristics.► pH was found to be critical in biosorption, with an optimum pH being 5.5.
