Total 938 actinomycete strains were isolated from 59 soil samples collected at Cheju island. All of these isolates were identified to the genus level based on morphological and physiological characteristics. As the result, 62.6% of those isolates were Streptomyces, 16.4% were Micromonospora, 8.6% were Nocardioform group, 2.2% were Actinomadura, 1.7% were Microbispora, 1.6% were Nocardiopsis, 1.0% were Streptosporangium, and 5.9% were the others. As the sources of soil, Streptomyces and Microbispora were abundant in grassland soil, Streptomyces and Micromonospora were abundant in field soil, and Micromonospora were abundant in forest soil. Especially, Nocardioform strains were abundant in natural caves.
