In a standing culture of strain A-1 at 30℃ in a soybean oil-inorganic salts medium (B in Table 1), rapid accumulation of the active substance, which has an ability to accerelate the velocity of oxygen absorption into unsaturated fatty acid, was observed during the logarithmic phase of growth (Fig. 2). The peroxide value (POV) of the oil was nearly unchanged until 15 or more days of incubation (Fig. 1), but the absorbance at 233mμ, which was probably caused by the formation of conjugated dienes, was increased during the same period (Figs. 4 and 5). When the strain was shaken in a medium of the same components, no activity was produced and the POV was kept nearly constant through the whole period of incubation (Fig. 3). The correlation between the active-substance production and the period of peroxidation of oil was discussed.From the activity-production data shown in Table 3 and the above-mentioned, it might be concluded that a medium containing nitrate and an insufficient supply of oxyge both were essential for production of the substance.
