[주요 연구 관심 분야 소개]
자연계에 널리 존재하는 하등 진핵 미생물 (미세조류, 곰팡이 등)은 유용 이차대사물질의 보고라
고 할 수 있으며, 최근에는 바이오에너지 활용 측면에서 각광을 받고 있습니다. 저희 실험실에서
는 이러한 하등 진핵 미생물인 미세조류와 곰팡이를 산업적으로 활용하여 보고자 하는 연구를
수행하고 있습니다. 이를 위하여 미세조류나 곰팡이의 유용 이차대사물질이나 바이오디젤의 원천
인 미세조류 지질의 생합성 과정을 제어하는 기작을 탐구합니다.
이를 바탕으로 분자생물학적인 유전자 조작을 통한 유망 균주 개발 및 후속적인 생물공학적 응
용을 추구합니다. 미세조류의 경우, 대량 배양 및 유용물질 생산 공정 확립을 위하여 광생물반응
기 개발이나 운전 등을 연구하고 있습니다. 또한 미세조류 대량 배양을 통한 생물학적 질소 인
제거 등의 하수 고도 처리 연구도 수행 중에 있습니다.
