dc.description.abstract유해 남조류를 친환경적으로 제어하기 위해 개발된 생물유래 물질인 naphthoquinone (NQ) 유도체의 현장 적용 가능성을확인하고자 하였다. 기흥 저수지 수변에 30 ton 규모의 mesocosm을 설치하여 현장 조건에서의 살조효과와 비생물학적, 생물학적요인을 모니터링하였다. NQ 2-0 물질을 처리한 결과, 대조구에서는 대상 조류인 Microcystis sp.의 세포밀도가 지속적으로 증가한반면, 처리구에서는 실험 초기 7.9×104 cells mL-1에서 접종 후 점진적으로 세포수가 감소하여 10일차 9.7×102 cells mL-1으로대조구 대비 99.4% 감소하였다. 실험 종료시인 15일차에는 Microcystis sp. 세포수가 100% 제거되었다. 대상 조류인 Microcystis sp. 종만을 선택적으로 제어하였을 뿐만 아니라, 다른 식물플랑크톤의 성장과 식물플랑크톤 종 다양성 지수도 증진되었다. 또한, 식물플랑크톤을 제외하고 NQ 2-0 물질에 의하여 물리․ 화학적요인 (수온, 용존 산소, pH, 전기전도도, 영양염)과 생물요인 (박테리아, HNFs, 섬모충, 동물플랑크톤)에 영향을 미치지 않았으며, 대조구와 처리구에서 유사한 경향이 관찰되었다.We evaluated the field application feasibility that biologically derived substances (Naphthoquinone derivate: NQ 2-0) can be used for the eco-friendly mitigation of natural harmful cyanobacterial blooms in freshwater. We conducted a 30 ton scale mesocosm experiment to investigate the effects of NQ 2-0 on biotic and abiotic factors in water collected from Gi-heung reservoir. In the mesocosm experiments, the abundance of Microcystis sp. was continuously increased in the control. However, the Microcystis sp. cell density was sharply decreased on the 10 th day. In the treatment, NQ 2-0 showed the strong and selective algicidal activity toward the target cyanobacteria (Microcystis sp.). Accordingly, the algicidal activity of NQ 2-0 compound increased gradually until 10 th , 15 th days and algal biomass was decreased to 99.4 and 100 %, respectively.NQ 2-0 compound was not only selective algicidal activity but also the growth of other phytoplankton and increased the Shannon-Wiener diversity index of phytoplankton. In the mesocosm experiments, the dynamics of biotic (bacteria, heterotrophic nanoflagellate, ciliates, zooplankton) and abiotic (water temperature, dissolved oxygen, pH, conductivity, nutrients) factors remained unaffected. These results suggest that NQ 2-0 could be a selective and ecologically safe algicide to mitigate harmful cyanobacterial blooms. In addition, it is believed that NQ 2-0 will play a major role in forming a healthy aquatic ecosystem by facilitating habitat and food supply of aquatic organisms.en_US
