방향족화합물을 생분해하는 미생물을 분리하여 생물학적 처리에 응용하기 위해 폐수 및 토양에서 150종의 균을 분리하였다. 그 중에서 COD 제거율과 방향족화합물의 이용능이 가장 우수한 HC107균을 선발하여 Pseudomonas sp.로 동정하였다. 활성슬러지 장치에서 Pseudomonas sp. HC107 배양액을 2ml/day씩 처리하면서 화학, 제약 및 도료공장의 폐수를 혼합하여 연속처리한 결과 처리수의 COD, BOD 및 phenol 제거율이 평균 92.5%, 95.53 및 93%.5로 나타났다.

The bacteria which can biodegrade aromatic compounds were screened from soil and wastewater. The isolated Pseudomonas sp. HC107 had high removal rate of COD and phenol. And also this strain grew on m-cresol, salicylate, toluene, 2, 4-D and benzene. When the strain culture (2 ml/day) was treated o...
The bacteria which can biodegrade aromatic compounds were screened from soil and wastewater. The isolated Pseudomonas sp. HC107 had high removal rate of COD and phenol. And also this strain grew on m-cresol, salicylate, toluene, 2, 4-D and benzene. When the strain culture (2 ml/day) was treated on continuous reactor at mixed wastewater from chemical, pharmaceutical and dye industry, the treatment rate of COD, BOD and phenol was to be about 92.5%, 95.3% and 93.5%, respectively.
