항균 및 살충물질 생산 균주의 분리와 동정 = Isolation and Identification of Microorganisms Producing Antibiotic and Inseticidal Substances

다국어 초록 (Multilingual Abstract)

Twenty seven out of ca. 5,000 actinomycete strains, which were isolated from soil collected throughout the country, showed anti-microbial effects against fungus, Rhizopus stronifer (ATCC6227a) and yeast, Candida albicans (ATCC10231). From these anti-fungal microorganisms, we further selected seven strains which seems to produce insecticidal substances with in vivo test, using silkworm, Bombyx mori. Morphological and biochemical experiments revealed that at least three strains out of seven were Streptomyces. Further investigations on the physical and chemical properties of these antifungal and insecticidal substances are now in progress.
