The crude active substance accumulated during the incubation of Achromobacter delica tulus atrain A-1 in the soybean oil-inorganic salt medium was compared with the nitrite solution with regard to their catalytic action on the oxidation of unsaturated fatty acid. The nitrite solution was found to be stable in pH range of 4.9 to 11.2 and was not inactivated by heat (121℃, 30min. at pH 7.8). In a low pH condition, disintegration of nitrite solution was accelerated by contact with unsaturated fatty acid. The optimum pH for O_2 uptake by the oxidation of unsaturated fatty acid with conjugated double bond was about 4.5 and the rate increased as the temperature increased up to 75℃. Through the time course of the incubation of A.delicatulus strain A-1,the increase of the concentration of nitrite ion was parallel to that of the active substance for fatty acid oxidation.
