[Superoxide dismutase, catalase and peroxidase of propionic acid bacteria].

The respiration of different species of propionic acid bacteria was found to be resistant to the inhibiting action of cyanide. Propionibacterium globosum, P. globosum (emm), P. vannielii, P. shermanii, P. petersonii, P. pentosaceum and P. raffinosaceum were shown to contain superoxide dismutase, catalase and peroxidase. The highest activity of catalase and superoxide dismutase was found in P. globosum and P. vannielii, the lowest one in P. shermanii and P. raffinosaceum. Peroxidase was detected in propionic bacteria for the first time.
