이 교수의 연구실은 주로 환경 미생물학과 분자 생물학을 융합하여, 메탄 생성균을 포함한 특정 미생물군집의 정량적 모니터링을 목표로 합니다. 실시간 PCR(TaqMan 시스템)을 활용한 그룹 특이적 프라이머 및 프로브 설계를 통해, 메탄형성 과정에서 핵심적인 역할을 하는 메탄형성균(특히 아세트산 분해성 메탄형성균)의 동역학을 정량적으로 분석합니다. 연구는 하수처리, 스위인 폐수 처리, 혐기성 소화기 등 다양한 환경 공정에서 미생물 군집의 구조와 기능적 역할을 규명하는 데 초점을 맞추고 있습니다.

Real-time polymerase chain reaction (PCR) is a highly sensitive method that can be used for the detection and quantification of microbial populations without cultivating them in anaerobic processes and environmental samples. This work was conducted to design primer and probe sets for the detection of methanogens using a real-time PCR with the TaqMan system. Six group-specific methanogenic primer and probe sets were designed. These sets separately detect four orders (Methanococcales, Methanobacte
The TaqMan quantitative PCR (QPCR) method was used to detect and quantify the 16S rRNA genes of aceticlastic methanogens at different taxonomic levels. Three different sets of primers coupled with a TaqMan probe for QPCR assays to detect the 16S rRNA genes of the order Methanosarcinales, as well as the families Methanosarcinaceae and Methanosaetaceae, were separately used. Using these primer and probe sets, the 16S rRNA genes of aceticlastic methanogens in samples from various anaerobic processe
The methanogenic community structures of four different anaerobic processes were characterized using a quantitative real-time PCR with group-specific primer and probe sets targeting the 16S rRNA gene (rDNA). The group specific primer and probe sets were developed and used to detect the orders Methanosarcinales, and the families Methanosarcinaceae and Methanosaetaceae. Two separate sets targeting the domains Archaea and Bacteria were also used. Each microbial population in different anaerobic pro
Swine wastewater was biologically treated to produce short-chain volatile organic acids (VOAs) in laboratory-scale continuously stirred tank reactors. The maximum production rates of acetic and butyric acids associated with simultaneous changes in pH and hydraulic retention time (HRT) were investigated, in which the degree of acidification of swine wastewater to the short-chain VOAs was <25% of influent chemical oxygen demand (COD) concentration. A constant inoculum system was used to minimize t
