초록

Pseudomonas sp. EL-041는 페놀로 적응된 활성오니로부터 분리되었으며, 페놀을 분해할 수 있는 동시에 trick-loroethylene(TCE)을 공동대사할 수 있는 세균이다. 본 연구에서는 Pseudomonas sp. EL-041에서 발현되는 trick-loroethylene 분해효소의 종류를 효소활성 측정 및 specific phenol oxygenase gene의 DNA sequencing을 통하여 조사하였으며, 그 결과 본 균주의 trichloroethylene 분해효소는 monooxygenase였으며, phenol hydroxylase로 추정되었다.

Pseudomonas sp. EL-041 was previously isolated from phenol-acclimated activated sludge. This bacterium was capable of degrading phenol and cometabolizing trichloroethylene (TCE). In this study, we report the identification of trichloroethylene- degrading enzyme in Pseudomonas sp. EL-041 by the investigation of enzyme activity and DNA sequencing of specific phenol oxygenase gene. As the results of experiment, trichloroethylene-degrading enzyme in Pseudomonas sp. EL-041 was monooxygenase and suspected to phenol hydroxylase.
