N2 - The effect of pH, oxygen and ferrous iron on growth and oxidation rates of iron-oxidizing bacteria (Gallionella spp and Leptothrix spp) as well as indirect effects, the most prominent being catalytic activity of the produced ferric iron deposits, were investigated. Deposits of biotic origin exhibit slightly lower surface oxidation rates compared to abiotically produced ferric iron. It was shown that the required habitat conditions of the studied species hardly overlap, but increase the pH/oxygen range of potential Fe(II) oxidation conditions. The study highlights the combined effect of microbial iron oxidation and catalytic properties of the Mn and Fe oxidation products.
