초록
고추 역병균(疫病菌)인 Phytophthora capsici의 방제(防除)를 위한 생물농약(生物農藥)을 개발(開發)하기 위하여 고추재배지토양(栽培地土壤)에서 균원시료(菌源試料)를 채취(採取)하여 우수(優秀)한 항균활성(抗菌活性)을 가지는 물질(物質)을 생산(生産)하는 균주(菌株)를 순수분리(純粹分離)하고 동정(同定)하였다. 대치배양(對峙培養)에서 A-183균주(菌株)가 A-35와 A-67보다 P. capsici의 생육을 크게 저해(沮害)하였으며 배양액(培養液)을 membrane여과 및 열처리(熱處理)(
This study was attempted to select an antagonist against Phytophthora blight of red-pepper caused by Phytophthora capsici. The three strains, A-35, A-67 and A-183 were isolated from the rhizosphere in soil where red-pepper had been cultivated continuously for a long time, and the strain A-83 was estimated to be the strongest antagonist against P. capsici. The A-183 strain was identified as a strain of Pseudomonas sp., showing the maximum antifungal activity, when cultured at
