이 교수의 연구실은 혐기성 소화 기반의 폐기물 처리 및 자원 회수 기술을 핵심으로 하며, 유기성 폐유출수와 가축분뇨 등의 생물학적 처리를 통해 메탄가스 생산과 오염물질 제거를 동시에 달성하고자 합니다. 특히, 미생물 간 전자 전달 메커니즘, 공동배양 미생물 군집의 역학, pH 조절을 통한 질소 제거 등 고도화된 생물공정 설계에 초점을 맞추고 있습니다. 또한, 생물의약품의 품질 평가 및 바이오시밀러 제품의 생물학적 활성 분석을 통해 환경공학과 생명공학의 융합 연구를 수행하고 있습니다.

Anaerobic digestion (AD) is an effective biological treatment for stabilizing organic compounds in waste/wastewater and in simultaneously producing biogas. However, it is often limited by the slow reaction rates of different microorganisms’ syntrophic biological metabolisms. Stable and fast interspecies electron transfer (IET) between volatile fatty acid-oxidizing bacteria and hydrogenotrophic methanogens is crucial for efficient methanogenesis. In this syntrophic interaction, electrons are exch
Shifts in bacterial and archaeal communities, associated with changes in chemical profiles, were investigated in an anaerobic batch reactor treating dairy-processing wastewater prepared with whey permeate powder. The dynamics of bacterial and archaeal populations were monitored by quantitative real-time PCR and showed good agreement with the process data. A rapid increase in bacterial populations and a high rate of substrate fermentation were observed during the initial period. Growth and regrow
This study investigated nutrient removal from anaerobic digestion effluent by cultivating mixed-culture microalgae enriched from anaerobic sludge under different pH conditions: R<sub>UC</sub> (uncontrolled), R<sub>7</sub><sub>-8</sub> (maintained at 7-8), and R<sub><8</sub> (maintained below 8). Significant amounts of NH<sub>4</sub><sup>+</sup>-N were lost by volatilization in R<sub>UC</sub> cultures due to increased pH values (≤8.6) during the early period of cultivation. The pH control strateg
