When Neurospora sitophila is cultivated on several agricultural products for fat resources at 30℃ for 5 days, it produces carotene. The fermented material is dried at 50℃, pulverized and extracted with ether. The extracted oil, which remained after evaporation of ether, contained much carotene.1. The loss of fat yield by sultivation of N.S was less than 0.5%.2. By cultivation of N. S. refractive index, saponification value and iodine value of the extracted oil decreased, and specific gravity and acid value increased. Acid value increased much more in comparison with other values.3. For the manufacture of oil with high carotene unit-value, rice-bran, rice-embryo and corn-embryo were fitted and the oil from the culture on rice embryo showed the highest unit-value and contained 86〜220 mg% of β-carotene.4. The retention of carotene in syo-bean oil which contained 3.3 mg% of that pigment was 64% after 1 month, 27% after 3 months, and soy-bean oil with addition of diphenylamine preserved 97% of carotene after 1 nonth, 60% after 3 months, while the retention in the oil from the culture on rice-embryo added with thiourea was 91% after 1 month.
