The Arrhenius plots of photosynthetic oxygen evolution in the blue-green algae Anacystis nidulans and Anabaena variabilis were composed of two straight lines with break points which were very close to temperatures for the onset of phase separation of the thylakoid membranes. Irreversible inactivation of photosynthesis began to appear at the same temperature as the onset of phase separation of the cytoplasmic membranes in A. nidulans. Electrolytes began to leak from the cytoplasm into the outer medium, indicating that the permeability of the cytoplasmic membranes increased when they entered the phase separation state. In A. variabilis, in which the cytoplasmic membranes had remained in the liquid crystalline state above 0°C, no irreversible damage to photosynthesis nor leakage of electrolytes was observed between 0 and 20°C. These findings suggest that photosynthesis of the blue-green algae is reversibly suppressed when only the thylakoid membranes are in the phase separation state, and irreversibly inactivated when the cytoplasmic membranes are in the phase separation state.
