Abstract

A total of four bacterial strains (namely Isolate 1 to Isolate-4) were isolated from sample collected at the dumping site nearer to a garage, Berhampur. The bacterial resistance was studied with the treatment of varied concentrations of Aluminum. It was observed that, Isolate -3showed highest tolerance in all Al2O3 concentrations (25 ppm, 50ppm, 100ppm, 150ppm) but showed highest tolerance in 100ppm concentration of Al2O3. Isolate 1 showed highest tolerance in 50ppm concentration of Al2O3. Isolate 4 showed highest tolerance in 25ppm concentration of Al2O3 .Isolate 2 showed highest concentration in 50ppm concentration of Al2O3 but showed weak growth with increased concentration. Antibiotic sensitivity test was conducted to check against four antibiotics-Streptomycin, Gentamicin, Cloxacilin, Rifampicin -using discs on the nutrient agar plates and it was found that, the highly aluminum resistant bacteria (Isolate-3) showed high resistance to antibiotic Cloxacilin and sensitive to Gentamicin, Streptomycin and Rifampicin but more sensitive to Gentamicin.
