SUMMARY. The acetate metabolism of Euglena grown on ethanol at pH 3.5 (Et-grown) differs from that of the same strain grown on acetate at pH 7.3 (Ac-grown) in several respects. Et-grown cells have a rate of acetate oxidation at pH 7.0 lower than that of Ac-grown cells. The rate of acetate oxidation by Et-grown cells is markedly increased at low pH, whereas that of Ac-grown cells is relatively independent of pH. At pH 5.5, the respiratory rate of Et-grown cells can be increased by increasing acetate concentrations up to 18.4 IBM, whereas that of Ac-grown cells is independent of acetate concentration above 4 mM. At pH 7.0, both types of cell are unaffected by changes in acetate concentration above 4 mM.Et-grown cells incubated in the presence of acetate for about 80 minutes frequently adapt to acetate, taking on characteristics similar to those of Ac-grown cells.
