In the present study, a bacterial strain was isolated from tannery effluent and identified as <em>Enterococcus casseliflavus. </em><span style="mso-bidi-font-style: italic;">It</span> showed a high level resistance of 800 µg/ml chromium. The minimal inhibitory concentration of chromium was found to be 512 µg/ml of potassium dichromate in Nutrient broth medium. The chromium adsorption was more significant by the live cells than killed cells at different time intervals. It was observed that, the inoculation of <em>Enterococcus casseliflavus </em><span style="mso-bidi-font-style: italic;">reduced the BOD and COD values of tannery effluent.</span> The maximum adsorption of chromium was at a temperature of 35ºC to 45ºC and at a pH<strong style="mso-bidi-font-weight: normal;"> </strong>of 7.0 to 7.5.</span>
