- Аннотация: Transformations of iron-containing minerals − synthesized ferrihydrite and natural siderite performed by a syntrophic co-culture of Candidatus “Contubernalis alkalaceticum” andGeoalkalibacter ferrihydriticus in presence of ethanol as the substrate for the obligate syntroph were studied by 57Fe Mössbauer and EPR spectroscopic techniques. Mössbauer spectra of solid phase samples were collected in the range of temperatures 5.5–300 K. X-band EPR studies were carried out at room temperature. The formation of a mixture of magnetite and maghemite, siderite and iron oxyhydroxycarbonate was found as the result of biogenic transformations of synthesized ferrihydrite. In the case of siderite, the formation of a mixture of magnetite and maghemite and iron oxyhydroxycarbonate was observed.
