This study demonstrated that the bacteria could adsorb Fe(3+) and reduce Fe(3+) to Fe(2+). Iron had significant bacteriostatic effects, which were directly proportional to the iron concentration and under the influence of pH and chelator. It presumed that the inhibition of Fe(3+) acts through the formation of hydroxyl free radicals.
