dc.description.abstract수중 내 함유된 고농도 perchlorate의 환원가능성을 perchlorate 환원 미생물인 신균주 Rhodococcus sp. YSPW01과YSPW02로 검토하였다. Perchlorate 환원 미생물은 혐기소화조 슬러지에서 분리 배양하였으며, perchlorate 환원능을 검토하기위해 전자공여체인 acetate를 사용하였다. YSPW01과 YSPW02는 perchlorate 82 mg L-1와 acetate 550 mg L-1에서 회분식 실험을 수행하였을 때, 반응 26시간과 9시간 후 각각 정상상태에 도달하였다. 이 때 perchlorate 환원은 8, 7시간 이내에 초기농도82 mg L-1에서 검출한계 이하(10 μg L-1)까지 제거되었다. 반응조 내에 acetate:perchlorate (w:w)비를 1:1에서 5:1로 증가한결과, perchlorate의 제거 속도는 YSPW01과 YSPW02 모두 2.1, 3.2 mg L-1 h-1에서 15, 15.5 mg L-1 h-1로 약 4.5배 증가하였고,최종 perchlorate는 검출한계 이하까지 제거되었다. 본 연구결과, Rhodococcus sp. YSPW01 및 YSPW02는 고농도 perchlorate제거에 적합하며, 신균주를 고농도 perchlorate 제거를 위한 생물학적 처리공정에 응용가능 할 것으로 판단된다. The feasibility of perchlorate reducing-bacteria isolated from the sludge of an anaerobic digester was determined usingammonium perchlorate in aqueous medium. Growth kinetics of the two perchlorate reducing bacteria including Rhodococcus sp. YSPW01 and YSPW02 were investigated using acetate as the electron donor in batch experiment. The growth of YSPW01 andYSPW02 reached a steady-state at 26 and 9 h, respectively. The initial perchlorate concentration was completely reduced within8 and 7 h by YSPW01 and YSPW02, respectively. The reduction rates were 2.1 and 15 mg L-1 h-1 for YSPW01, and 3.2 and 15.5mg L-1 h-1 for YSPW02, at 1:1 and 5:1 ratios of acetate:perchlorate (w:w), respectively. In this study, the bacteria Rhodococcussp. YSPW01 and YSPW02 demonstrated a potential for the perchlorate reduction, which could be further investigated for developmentof an efficient strategy to treat the perchlorate contaminated waters.en_US
