    Based on “ Molecular Microbiology and Biotechnology ”, our laboratory is seeking solutions in tackling energy and environmental issues by taking advantages of the useful bioconversion capability of microorganisms and their enzymes. We are currently working on studying fundamental novel scientific knowledge and developing technologies for the conversion of renewable biomass to value-added chemicals, including biofuels, gasification, enzymes and fermentation.

    We work as a team among three teams, and have a very good organization. Here's a snapshot of each team’s research activities.

    바이오 연료 및 바이 오 화학 산업은 미래 지향적이고 환경친화적인 바이오 기술 이다 . 바이오 연료 및 화학 제품의 산업화를 위해서는 저비용의 환경친화적인 바이오매스를 사용하여 경제성 있는 공정에 대한 과학적 접근이 필요하다 . 따라서 본 연구실에서는 효율적인 당화를 위한 시스템을 구축하고 , 미생물의 대사 경로를 조절하여 특정 기능을 제어하거나 증폭시킬 수 있는 산업 균주를 개발하여 대량 생산이 가능하게 하는 연구가 진행중에 있다 .
    경제적인 바이오 연료 생산을 목적으로 목질계는 물론 해양계 바이오 매스로부터 슈가플랫폼을 구축하기 위하여 당화 균주를 개발 중이며 , 효과적인 분해를 위한 효소공학 및 나노융합 기술을 응용하여 고효율의 효소를 개발하고 있다 . 목질계나 해양계 바이오 매스를 바이오 에탄올 생산에 이용하기 위해 분해 효율이 높은 Enzyme nano-complex( 효소나노복합체 ) 인 cellulosome 의 형성 기작과 cohesin-dockerin 상호 작용을 응용하는 연구가 진행하고 있으며 , 이 원리를 이용한 minicellulosome 의 생성 및 응용 연구가 이루어지고 있다 . 또한 세포 표면 디스플레이 시스템을 응용한 나노암 (Nano-arm) 탑재 슈퍼 산업 균주의 개발을 통하여 공정을 최적화 시키는 시도와 차세대 유전체 기능 분석 및 대사제어를 통한 미생물 오믹스 (Omics) 정보 시스템을 개발하고 있다 . 미생물을 이용한 바이오에너지 및 바이오화합물를 생산하기 위하여 대사공학 및 시스템생물공학을 기반으로 하는 균주 개발의 중요성이 대두됨에 따라 인위적으로 세포의 대사과정을 조절하여 바이오화합물 및 바이오 연료와 같은 유용 생물소재의 대량생산을 위한 연구를 진행하고 있다 .

    본 연구실은 국내 바이오리파이너리의 선도적인 연구실로서 자리잡기 위하여 총 세팀으로 구성이 되어 연구를 진행 중에 있으며 연구실을 구성하는 세 팀들은 미생물의 물질대사적 원리를 밝히고 이를 대사공학을 기반으로 응용한 유용한 균주의 개발 , 효소에 대한 유전학 및 생화학 기반의 과학적 원리를 기반으로 바이오매스의 활용을 위한 고효율의 효소 개발 , 효소 복합체인 셀룰로좀 (Cellulosome) 의 원리를 밝히는 오믹스 (Omics) 개념의 Cellulosomics 학문 연구를 각각 목표로 하고 있다 . 세 팀간의 유기적인 연구 및 연구 결과의 내부적인 공유를 통하여 저비용의 환경친화적인 바이오매스를 사용하여 경제성 있는 공정에 대하여 과학적으로 접근하고 있다 . 따라서 , 본 연구진에서는 바이오매스의 효율적인 당화를 통하여 저비용의 당을 확보하고 바이오리파이너리 최종 생산물인 바이오 연료 및 고부가가치 바이오화합물 생산을 위한 미생물 균주개량에 대한 시스템 개발 , 신규 미생물 탐색 , 대사공학 및 단백질 공학을 이용한 발효 및 생산공정의 최적화 , Omics 등의 신규 툴을 이용하여 C2, C3, C4 등의 범용 화학소재 생산을 위한 플랫폼 미생물을 제작하고 이를 통하여 platform chemical 을 생산 하고 있다 .
    궁극적으로 , 본 연구실에서는 바이오매스 유래의 각종 신규 기능성 단량체 , 고분자 중간체 , 비이오플라스틱 , 바이오에너지 및 고부가가치 정밀화학제품을 생산할 수 있는 핵심 기반기술을 개발하여 기존의 화학산업을 “ 저탄소 녹색성장 ” 산업으로 전환하는 국가적 비전에 부응하고자 한다 .
