• Growth, respiratory activities and electrophoretic characteristics of phosphatase and catalase in three strains of Ceratocystis fimbriata (sweet potato strain, coffee strain and prune strain) differing in pathogenicity on sweet potato roots were investigated. There were no significant differences in either growth kinetics or respiratory activity among the strains. Potassium cyanide and antimycin A inhibited oxygen uptake in sweet potato and prune strains. The oxygen uptake of endoconidia of coffee strain was stimulated by these inhibitors. Mitochondria were prepared from endoconidia and mycelia of each strain, and enzyme activities of the electron transport system were measured. NADH_2: cytochrome c oxidoreductase activity of coffee strain was higher than that of the other strains. The electrophoretic phosphatase pattern of coffee strain was identical with that of sweet potato strain, but differed from that of prune strain. On the other hand, the catalase zymogram from prune strain was closely related to that of sweet potato strain, but not to that of coffee strain.
