Byline: Farah R. Shakoori, Shagufta Tabassum, A. Rehman and A. R. Shakoori Abstract.- In this paper the ability of Bacillus pumilus, Alcaligenes faecalis and Staphylococcus sp. to reduce Cr6+ into Cr3+ was evaluated. B. pumilus could tolerate Cr6+ up to 2 mg/ml. A. faecalis and Staphylococcus sp. resisted Cr6+ up to 1.4 and 1.6 mg/ml, respectively. B. pumilus and Staphylococcus sp. showed optimum growth at pH 8 while A. faecalis showed maximum growth at pH 7. All bacterial strains showed optimum growth at 37oC. B. pumilus was found sensitive against amoxicillin and tetracycline while found least sensitive against polymyxin B. A. faecalis was found sensitive to tetracycline while showed least sensitivity against amoxicillin. Staphylococcus sp. showed high sensitivity against vancomycin while minimum against erythromycin.
