The aim of this study was to isolate and identify the arsenic resistant bacteria. The experiment was conducted through January 2010 to May 2010 at Microbiology Laboratory of Institute of Applied Medicines and Research, Ghaziabad, Uttar Pradesh. The water samples were collected from different polluted water bodies. Twenty one arsenic resistant bacterial strains were isolated form polluted water. Arsenic resistant bacteria were isolated by growing on nutrient agar medium impregnated with high concentration (20 mg/mL) of As2O3 and As2S3. Four isolates were found more resistant and finally selected for their morphological and biochemical studies in details. All four isolates were able to tolerate very high concentration (> 0.2% or 20 mg/mL). The optimum temperature and pH for growth of all four strains were 30-37 oC and 7.0-8.0 respectively.
