Heavy Metal Removal by Magnetospirillum Strains and Its Possible Use in the Treatment of Tannery Effluents

Heavy metals are a threat to the sustainable environmental condition causing ecological imbalance. MTBs utilize iron via metal transport system known as biomineralization Therefore, strains MSR-1, RJS2, RJS5, RJS6, and RJS7 were exposed (1,10 ppm) Cd, Mn, Pb, Ni, Zn, Cr, Co sole electron donor, time/days for efficient biosorption optimized. The AAS analysis revealed that RJS2 strain showed maximum (1 of Pb (96%). produced all metals. Biosorption by MSR-1 was more at 10 ppm. However, RJS5 displayed better sorption properties against (93.42%) 50 Further exposure from tannery effluents yielded RJS6 [nickel (88%) zinc (81%)] [manganese (82%) cobalt (96%)] potent strains. heavy removal in can be further explored on an industrial scale.
