摘要：

Oscillatoria limnetica grown photoautotrophically under aerobic or anaerobic conditions contained a single superoxide dismutase (SOD) of identical electrophoretic mobility in both cases. Its activity was cyanide resistant and H2O2 sensitive, implicating Fe-SOD. The enzyme level was high in aerobically and low in anaerobically growing cells. Anaerobically grown cells were more sensitive than aerobic to photooxidation, as expressed by bleaching of phycocyanin and disintegration of the trichomes. © 1979 Springer-Verlag.
