The document describes a study examining the ability of Magnetospirullum sp. VITRJS5 to reduce perchlorate. The study cultured the microorganism with acetate as the electron donor and oxygen, nitrate, or perchlorate as the electron acceptors. Statistical analysis was conducted and showed that M. sp. VITRJS5 was able to reduce oxygen, nitrate, and perchlorate while growing. Growth curves and mean reduction levels are presented for the different conditions tested.
