Perchlorate (ClO

4-) contaminated water is becoming a wide-spread problem as

more sites are being identified worldwide. Biological perchlorate reduction is a promising

alternative to conventional physical/chemical treatment processes and has the advantage

of reducing perchlorate to the benign products, chloride and oxygen. A number of

bacteria are capable of reducing perchlorate using a variety of electron donors including

organic carbon compounds, hydrogen, iron, and reduced sulfur compounds. Previous

studies in our laboratory successfully used a novel, sulfur oxidizing bacterial consortium

(SUPeRB) to reduce perchlorate in both batch culture and in packed bed reactors (PBR).
