The biological reduction of soluble chromate(VI) compounds by bacteria was investigated as a possible treatment for industrial wastewater. A chromate(VI) reducing bacterial strain CRM100 was isolated from a wastewater treatment plant and identified as Pseudomonas aeruginosa. Strain CRM100 using citrate as carbon source, was able to reduce 99.8% of chromate(VI) added at a concentration of 100mgL(-1). The results demonstrated the potential applicability of CRM100 for the bioremediation of heavy metal contaminated wastewater.
