Abstract:
Ten heavy metal resistant strains were isolated from samples of soil, water and rhizosphere of plant Cynadon Dectylon of Kasur sector. Among these bacteria, four strains Cr-1, Cr¬2, Cr-3 & Cr-4 were showed the resistant to chromium up to 300 mg/L, two strains Cd-1 & Cd-2 resisted cadmium up to 100 mg/L, two strains Cd-3 & Cd-4 resisted cadmium up to 50 mg/L and two strains (Hg-1, Hg-2) were observed resistant to mercury up to 100 mg/L. Their morphological and colonial characteristics were investigated. The families of isolated bacteria are reported i.e. Azotobacteriaceae (Cr-1), Enterobacteriaceae (Cr-2, Cr-3, Cr-4, Hg-2) and Neisseriaceae (Cd-1, Cd¬2, Cd-3, Cd-4, Hg-2).
