Abstract

To select microorganisms that exhibit antifungal activity against the fungal pathogens of pepper, Phytophthora capsici and Colletotrichum acutatum, soil samples from a forest and natural fields of Gajang-Dong, Sangju-city were tested in vitro and in vivo. Streptomyces griseofuscus 200401 was finally selected throughout antifungal activity test with dual culture, culture broth, and fruits. For the identification of the strain, nucleotide sequences of 16S rDNA and whole cell fatty acids were analyzed. It is like that the strain 200401 may be a novel biological control agent that can reduce application of chemical fungicides to control late blight and anthracnose on pepper.

고추 탄저병과 역병균에 항균활성을 보이는 미생물을 산림과 비 경작지 토양으로부터 분리하였다. 대치배양, 배양액 및 열매를 이용한 간이 검정을 통하여 Streptomyces sp. 200401 균주가 최종 선발되었다. 선발 균주는 16S rDNA 염기서열과 지방산 분석을 통하여 Streptomyces griseofuscus으로 동정되었다.
