초록
Streptomyces의 분류, 분포 및 항생물질 생산특성을 알아보고자 각 토양으로부터 총 826 균주의 Streptomyces를 분리하여 토양별 분포를 조사하고 항생물질 생산능을 검정하였다. 토양별 방선균류의 분포를 조사한 결과 참나무, 잔디, 아카시아, 사과나무, 고추밭, 배추밭, banana 온실 등지에서
Out of 826 isolates of Streptomyces isolated from different soils, their distribution and antibiotic productivity were investigated. Distribution of the organism in the soil was affected by the soil conditions and plants. The highest isolation frequency was occurred from Quercus forest, Robinia forest and grass field, while soils from orchards and cultivating fields showed low density of Streptomyces. More than 49% of the isolates showed antibacterial activity against Bacillus subtilis, Erwinia carotovora subsp. carotovora and Xantomonas campestris pv. oryzae and about 40% of the isolates showed antiyeasty activity against Saccharomyces cerevisiae but only a few isolates showed antibiotic activity against E. coli and Pseudomonas solanacearum. Forty isolates of the Streptomyces showed strong antifungal activity against Pyricularia oryzae. Rate of isolation of Streptomyces was the highest on starch agar among the eight media tested. Antibiotic productivity of the isolates was the highest on potato sucrose agar medium among the 5 media tested.
