Enzymatic reduction of iron oxide by fungi.
The occurrence of the iron-reducing phenomenon among some common fungi was studied. Results indicated that (i) the reduction of ferric iron to the ferrous state by fungi seems to be restricted to nitrate reductase-inducible strains such as Actinomucor repens, Alternaria tenuis, Fusarium oxysporum, and F. solani and (ii) the amount of dissolved ferrous iron may be reduced progressively by increasing the amount of nitrate added to the medium. Compared with a complex medium (Sabouraud medium), less iron became reduced if NO(3) was the only nitrogen source (Czapek Dox medium). These data strongly support the view that ferric iron is acting as an hydrogen acceptor in respiration, competing with nitrate for electrons that are mediated by the enzyme nitrate reductase. The significance of this property from an ecological viewpoint is discussed.
