dc.description.abstract 전세계적으로 연안해역에서 확산되고 있는 유해유독성 식물플랑크톤의 대발생은 수산자원생물자원에 심각한 피해를 입힌다. 본 연구에서는 유해성 미세조류 대발생을 제어하기 위해 개발된 신물질 Thiazolidinedione 유도체(TD49)의 살조능을 유해성 미세조류 성장단계(초기성장기, 대수증식기, 안정기)에 따라 조사하였다. TD49는 Heterosigma akashiwo , Chattonella marina 그리고 Chattonella sp.의 세포를 사멸시켰으며, 특히 낮은 농도( 0.02μM )의 TD49는 대수증식기와 안정기보다 초기 성장기에서 우수한 살조효과를 보였다. 또한 모든 성장단계에서 유해생물을 제어 할 수 있는 TD49의 농도는 2μM 로 측정되었다. 무각 편모조류인 Heterosigma akashiwo , Chattonella marina 그리고 Chattonella sp.은 세포벽이 약하여 TD49물질에 의해 세포가 쉽게 파괴되어 우수한 살조효과를 보였다. 결과적으로 본 연구에서 개발된 Thiazolidinedione 유도체(TD49)는 유해적조생물 H. akashiwo , C. marina 그리고 Chattonella sp.를 제어할 수 있는 우수한 물질로 판단되었으나, 추후 현장 실용을 위해 메소코즘과 같은 인공생태계를 이용한 해양생태계 위해성 평가가 체계적으로 추진되어야 한다. Worldwide development of harmful algal blooms causes serious problem for public health and fisheries industries. To evaluate the algicidal impact on the harmful algae bloom species in aquatic ecosystems of coast, a new algicide thiazolidinedione derivative (TD49) were tentatively examined in the growth stages (i.e., lag, logarithmic and stationary phase) of rapidophyceae Heterosigma akashiwo , Chattonella marina and Chattonella sp..Three strains could easily destroy in the lag phase due to relatively weak cell walls than those of the logarithmic and stationary phase. It is thought that inoculation of TD49 substances into initial or developmental natural blooms with a threshold concentration ( 2μM ) can maximize the algicidal activity. Also, bio-chemical assays revealed that the algicidal substances from all culture strains were likely to be extracellular substances because those cells have easily destroyed in cell walls. On the other hand, natural zooplankton communities were influenced within the exposure experiments of 2μM , which is showed the maximum algcidal activity of tested organisms. These results indicate that although the TD49 substance is potential agents for the control of H. akashiwo , C. marina and Chattonella sp. in the enclosed eutrophic bay and coastal water, more detailed research of acute toxicity effect on high trophic organism in marine ecosystems need to be conducted. -
