Abstract
Cells of the archaebacterium Methanosarcina barkeri were grown strictly anaerobic in defined media. 57Fe-Mössbauer Spectroscopy of methanol grown cells oxidized in the presence of air demonstrated only the state of Fe3+ whereas active cells under reducing conditions offered spectra of two additional iron sites in the Fe2+ state. Furthermore the 57Fe hyperfine interaction data at different temperatures gave evidence that cells cultivated with methanol or acetate as substrate contained ferredoxin like compounds.
