Abstract
Neutrophilic Fe(II) oxidizing microorganisms are found in
many natural environments. It has been hypothesized that, at low
oxygen concentrations, microbial iron oxidation is favored over
abiotic oxidation. Here, we compare the kinetics of abiotic Fe(II)
oxidation to oxidation in the presence of the bacterium Leptothrix
cholodnii Appels isolated from a wetland sediment. Rates of Fe(II)
oxidation
