The two strains of Catenularia sp. HFES No. 179 and 136 were isolated, the former from Yokan and the latter from the air of Yokan factory. For the purpose of preventing mold, we examined the morphological natures and the reactions of these two strains for the fundamental physical and chemical, treatments. Morphologically, we observed and made a new description about the constriction on for the conidiophores of these strains, which was missing in the description of Catenularia fuliginea SAITO. Physiolgically, it was necessary for isolation and culture of these strains, that the medium had high osmotic pressure with 25 to 80 Atm., and optimum pH for growth are 5 to 7. Conidia die by 5 min. heating at 60°, 10 min. at 50°. By the irradiation of ultraviolet ray of 15 Watt germicidal lamp from 50cm distance for 15 min. about 95% or more conidia die. And we have tested the fugistatic agents against these two strains.
