The soil samples of old Zawar mine sites were sandy texture, basic, electric conductivity range from 16 to 59 dSm −1 with a high content of heavy metals of Zn, Pb, Cd, and Fe, indicating poor soil-health. Two bacterial isolates Pseudomonas aeruginosa HMR1 and P. aeruginosa HMR16 (GenBank-accession-n...
