Chika Tada 교수의 연구실은 천연 유래 미생물, 특히 루미너 미생물과 메탄형성 고세균을 중심으로 한 생물학적 분해 및 메탄 생성 메커니즘을 연구합니다. 린세균이 분해하는 리그노셀룰로오스 기반 생물매질의 효율적 활용을 위해 엔도글루카나제 및 킬라나제 등의 효소 활성 메커니즘을 규명하고 있으며, 메탄 생성 미생물의 고밀도 고착을 위한 표면 기반 기술 개발도 진행 중입니다. 이는 청정 에너지 생산과 온실가스 감축에 기여하는 지속 가능한 생물공학 기반 기술 개발을 목표로 합니다.

Treatment with rumen microorganisms improves the methane fermentation of undegradable lignocellulosic biomass; however, the role of endoglucanase in lignocellulose digestion remains unclear. This study was conducted to investigate endoglucanases contributing to cellulose degradation during treatment with rumen microorganisms, using carboxymethyl cellulose (CMC) as a substrate. The rate of CMC degradation increased for the first 24 h of treatment. Zymogram analysis revealed that endoglucanases of
Treatment with rumen fluid improves methane production from non-degradable lignocellulosic biomass during subsequent methane fermentation; however, the kinetics of xylanases during treatment with rumen fluid remain unclear. This study aimed to identify key xylanases contributing to xylan degradation and their individual activities during xylan treatment with bovine rumen microorganisms. Xylan was treated with bovine rumen fluid at 37°C for 48 h under anaerobic conditions. Total solids were degra
Various support carriers are used for high-density retention of methanogenic archaea in anaerobic wastewater treatment systems. Although the physicochemical properties of carrier materials and microorganisms influence the adhesion of methanogenic archaea, details about the underlying mechanism remain poorly characterized. We applied seven types of chemical surface modifications to carbon felts to clarify the adhesion properties of <i>Methanothermobacter thermautotrophicus</i>, a representative t
