Morphology of typical P. manganicum E-1129 cell formation. Transmission electron microscope micrographs, Pt/C shadowed. Bar = 1 um. - Source:1Aerobic heterotroph
Pedomicrobium are aerobic, heterotrophs, able to deposit oxidized iron compounds and/or manganese oxides when cells are grown in the presence of fulvic acid, iron sesquioxide complexes, elemental iron powder, FeS or iron paper clips, and Mn(II) respectively 1. Cells may be spherical, oval, tetrahedral, or rod, pear or bean shaped 1. Polyphosphate granules can be present 1 2. The in situ physiology of Pedomicrobium in activated sludge has not been determined.
