| Abstract: | A respiration-deficient mutant of Saccharomyces cerevisiae produced by acriflavin treatment was assayed for ubiquinone content. The ubiquinone content of aerobically cultured cells of the mutant ranged from of that of the normal yeasts, whereas the anaerobically grown mutant contained considerably less ubiquinone than the aerobically grown mutant cells. Aeration of anaerobically grown respiration-deficient mutant cells increased the concentration of ubiquinone to the level of the aerobically grown mutant. |
