초록
고추 역병균(疫病菌)(P. capsici)에 우수(優秀)한 항균활성(抗菌活性)을 가진 3가지의 항균물질(抗菌物質)을 Pseudomonas sp. A-183 배양액(培養液)으로 부터 분리(分離) 정제(精製)하였다. 분리(分離)된 3가지의 항균물질(抗菌物質)에 대한 분자구조식(分子構造式)을 구명(究明)하기 위하여 UV, IR,
This study was carried out to identify the three antifungal substances isolated from the culture medium of Pseudomonas sp. A-183 which is antagonistic against Phytophthora capsici. The substance A and B showed positive reactions at the Molish test and Anthrone test, but negative one at the Fehling test, strongly suggesting that both substance A and B had nonreducing sugar frameworks. The substance C only exhibited the phenomenon of the UV induced fluorescence. From the qualitative analysis with the spectroscopic techniques such as UV, Mass, IR and NMR, the substance A and B were known to be composed to sugar and fatty acid, and showed a base peak of 171(m/e). It was identified that substance A was
