Abstract
Antifungal substances against three plant pathogenic fungi, Phytophthora capsici, Phytophthora nicotianae var. parasitica and Rhizoctionaia solani were fractionated cultures of Streptomyces sp. A-2 strain isolated in Korean soils. Characterizations of active substances related with antagonistic effects were follows : 1. The excellent media which showed the transfer efficiency of antagonistic substances from Streptomyces sp. A-2 strain G.Y.B and B.H.I. among four that are glucose yeast broth (G.Y.B),
우리나라 28개 지역(地域) 논밭 토양에서 수집한 시료에서 방선균(放線菌) 108주를 분리하고, 고추역병균, 참깨역병균 및 채소입고병균에 종합적으로 항균력을 갖는 Streptomyces sp. A-2를 선발하여 그 활성물질(活性物質)의 특성을 조사한 결과는 다음과 같다. 1. G.Y.B.,
