Leptothrix sp. was cultivated in Lieske 's medium in the presence of Al foil covered by anodic Alumina . Samples of biomass deposited on lamellae were studied by the methods of infrared, Mössbauer , and X‐ray photoelectron spectroscopy. Sole deposition of γ ‐Fe OOH on the lamellae was found to take place. This result is explained by the influence of γ ‐Al OOH ingredient in the used support due to crystal structure similarity. Thus, iron oxyhydroxide crystallisation could be directed during bacteria cultivation. The catalytic activity of deposited γ ‐Fe OOH was examined in CO oxidation.
