SUMMARY Growth and chlorophyll synthesis by the green alga Golenkinia cease after approximately 60‐hr incubation in 0.01 M sodium acetate. These effects are immediately preceded by a rapid rise of the pH of the medium to 8.6–8.8 due to acetate uptake. The pH kinetics are due to a gradual loss of the phosphate buffer, not to the induction or activation of acetate assimilatory enzymes. However, neither high pH nor sodium acetate alone is sufficient to inhibit cell division and bleach the algae; both must be present. Additional experiments support the hypothesis that acetate alters the cells so that they become sensitive to high concentrations of OH − ions.
