초록

염색 공단 폐수로부터 채취한 시료에서 Remazol Black B를 유일 탄소원으로 성장할 수 있는 미생물들을 순수 분리 하고, 염료 분해능이 가장 우수한 균주를 API 20E kit를 이용해 생화확적 특성을 분석해 본 결과, Stenotrophomonas maltophilia EJ-211로 명명하였다. S. maltophilia EJ-211에 의한 난분해성 반응염료인 Remazol Black B 분해 반응을 분석한 결과, 보조 탄소원으로 포도당 1.0%(w/v), 질소원으로 trypton peptone은 1.0%(w/v), 3$0^{\circ}C$, pH 6.5의 최적 조건을 결정할 수 있었다. 호기적 조건에서의 S. maltophilia EJ-211의 Remazol Black B는 28시간 동안 약 86% 수준의 염료 분해능을 보여주어 Remazol Black B에 대한 생분해능이 아주 우수함을 확인할 수 있었다.

A reactive dye-degrading bacterium was isolated from textile waste water and it was identified as Stenotrophomonas maltophilia based on its biochemical characteristics. The effects of additional carbon and nitrogen sources were investigated for the development of an optimal medium for biodegradation of Remazol Black B by 5. maltophilia. The optimal pH and temperature were determined to be 6.5 and 3$0^{\circ}C$, respectively. Remazol Black B with the initial concentration of 50 ppm could be degraded up to 86% within 28 h.
