Changsha 410083, China）Abstract: The alkaline wastewater containing chromiumCr(VI was treated with C-1 strain identified as achromobacter isolated from sludge nearby the chromium slag pole site. The optimum conditions of growth of the strain and factors affecting reduction efficiency of Cr, such as the temperature, the pH value of solution, the concentration of Cr and the treatment time, were studied.
