Abstract

This study was performed to investigate the antibacterial activities and the minimal inhibitory concentration (MIC) of 6 strains of Beauveria bassiana against mulberry pathogenic bacteria. The antibacterial activities and the MIC were measured using paper disc method and broth dilution method, respectively. The antibacterial activities were found out just B. bassiana J200, and shown at 13 mm from Erwinia rhapontici KACC 10407 and at 17 mm from Pseudomonas syringae KACC 10390 and Xanthomonas campestris KACC 12134. The MIC were all observed at 4.0% from E. rhapontici KACC 10407, P. syringae KACC 10390 and X. campestris KACC 12134. The results suggest that B. bassiana could play a good role for biological control against mulberry pathogenic bacteria.

뽕나무병원성세균에 대한 Beaveria bassiana 6균주의 항균활성을 paper disc법으로 조사하였고 최소성장저해농도(MIC)를 액체배지희석법으로 조사하였다. 항균활성은 B. bassiana J200에서만 나타났으며, Erwinia rhapontici KACC 10407에서는 13mm, Pseudomonas syringae KACC 10390와 Xanthomonas campestris KACC 12134에서는 각각 17 mm의 항균활성이 나타났다. MIC 측정 결과 E. rhapontici KACC 10407, P. syringae KACC 10390 및 X. campestris KACC 12134 모두 4.0%에서 MIC를 보였다. 이상의 결과로 B. bassiana의 뽕나무병원성세균에 대한 생물학적 방재제로서의 이용 가능성을 확인하였다.
