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 maxi...
