 Title    Schwermetalle in höheren Pilzen, II * Mangan und Eisen Heavy Metals in Higher Fungi, II Manganese and Iron  
 Abstract    In several series of 262 samples, Higher Fungi, especially from the Tremellales and Gastero-mycetes, were analyzed by atomic absorption spectroscopy on their content of the trace metals manganese and iron. Both elements were found to be present in higher concentrations in some species of the Trem ellales and P hallales. In the case of wood-destroying fungi, the Fe-and Mn-contents of the substrates were compared to those of the corresponding fungi. Only the species with the highest level of these metals reached the same contents as their substrates or a poor enrichment. Among the remaining species of the Higher Fungi, only in the case of the epigean P hallales, a possible biochemical role of manganese has been discussed.

 Title    State of Iron in the Archaebacterium Methanosarcina barkeri Grown on Different Carbon Sources as Studied by Mössbauer Spectroscopy  
 Abstract    Cells of the archaebacterium Methanosarcina barkeri were grown strictly anaerobic in defined media. 57Fe-Mössbauer Spectroscopy o f methanol grown cells oxidized in the presence o f air demonstrated only the state o f 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.

 Title    Hairs o f Soybean (Glycine max)  
 Abstract    Root hairs of soybeans (Glycine max), target cells for infection by Rhizobium japonicum accumulate iron more than 10-fold, cobalt more than 8-fold and calcium more than 7-fold compared to the other parts of the root system. In root hairs of wheat (Triticum aestivum) a much smaller accumulation of these elements was found. The symbiont of Glycine max, Rhizobium japonicum, is known to have a high requirement for iron, cobalt and calcium.

 Title    Bleom ycin-Iron C om plex and Oxygen Activate Algal R ibonucleotide Reductase  
 Abstract    Ribonucleotide reductase of green algae (Scenedesmus obliquus) is a radical-containing enzyme which rapidly loses activity under anaerobic conditions. Reactivation in the presence of air is enhanced by 10 |j.m iron(II)-bleomycin chelate. The reaction lends new biochemical potential to the antibiotic and should be valuable in mechanistic studies of ribonucleotide reduction.
