Pseudomonas plycolor was used to investigated the optimal culture condition to examine the various properties of superoxide dismutase (SOD). this SOD was inhibited by $H_2O_2$, azide ion, but not by cyanide ion. This result indicates that the enzyme might be a Fe-SOD. The composition of optimal culture medium for the enzyme production was 3% of glycerin, 1% of polypeptone, 0.5% of meat extract, 0.2% of KCI and the initial ph was 9.0 . The cultivation for the enzyme production was carried out in 500ml shaking flask containing 100ml of the optimal medium at $30^{\circ}C$ on a reciprocal shaker. The enzyme production reached maximum at 15hrs of cultivation and then declined sharply afterward.
