초록

벤젠의 제거에 효과적인 MY 혼합균주를 획득하였으며, 이중 우점종은 Rhodococcus ruber DSM 43338T로 밝혀졌다. MY 혼합균주가 함유된 유동층 생물반응기는 벤젠에 대한 임계 제거율 (critical removal rate)은 32 g/㎥ h로 나타났으며, 17일간의 연속가동에서도 안정적인 처리효율을 보여주어서, 벤젠의 제거에 뛰어난 성능을 보여주었다.

MY microbial consortium were obtained from sludges of wastewater to degrade benzene effectively and Rhodococcus ruber DSM 43338T was identified as major microorganism. The fluidized bed biofilter including MY microbial consortium showed critical removal rate of benzene at 32 g/㎥ h, and maintained stable removal efficiency for 17 days of continuous operation.
