Abstract:
It has been found that yeast cells suspended in saline containing ferrous salts could oxidize them to the ferric form by excreting H2O2 and ammonia. Excretion of ammonia accelerates spontaneous oxidation of iron by molecular oxygen. Ammonia generation probably results from the degradation of amino acids within starving cells.
