초록

본 연구에서는 두 균주, Bacillus sp. LP03, TBM40-3의 biosurfactan에 대한 생육 시 적절한 온도와 유화활성에 대한 실험을 행한 후 가장 적절한 조건에서 배양하였고, 이미 항진균성과 유화활성에 대해 실험실 수준에서 검증된 TBM40-3뿐 아니라 분리되어 보관되어 있는 균주, LP03 또한 실험실 수준에서 항진균성 및 유화활성이 확인되었고 이후에 시행한 부추에 생기는 병인 B. cinerea에 대한 항진균성 및 생육조사를 시행한 결과 이미 항진균성과 유화활성이 확인되어있던 TBM40-3에 비해 그 효과가 우수할 뿐 아니라 생육 촉진효과를 확인할 수 있었다.

This report investigates antifungal activity and effects of growth promotion by biosurfactant produced from Bacillus sp. LP03 and TBM40-3 against fungus causing plants disease (Glay Mold-Botrytis cinerea). Antifugal activity against B. cinerea infeeted to leek (Allium tuberosum Rottler) exhibited better than antifungal agent farming drug (smilex, Dong bang agro., Seoul, Korea.) through the field test. After infected by plant's disease, the leaves growth and number are maintained under presenting biosurfactant produced strains. Especially, one of the strains, named Bacillus sp. LP03 showed strong antifungal activity on field studies.
