Active growth of Aspergillus oryzae was observed when conidia were inoculated into a medium containing antimycin A. Immediately after adding antimycin A, to young mycelia germinated in its absence, growth stopped, but began again after several hours. This restored growth was antimycin A-insensitive. Percentage germination was the same in the presence and absence of this drug. It seems that drug-resistant germination and growth do not result from selection of resistant cells but result from induction of antimycin A-insensitive mitochondria in the whole population. Endogenous respiration of cells germinated in the absence of antimycin A was inhibited by this drug, whereas that of cells grown in the presence ofantimycin A was completely insensitive. Antimycin A-sensitivity of cellular respiration seems to determine the effect of this drug on mycelial growth. Mitochondria were isolated from mycelia grown in the presence and absence of this drug. The difference in antimycin A-sensitivity in endogenous respiration was attributed to a difference in properties of the mitochondrial respiratory systems
