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