The bacterial community structure in a biological reactor fed influent from a wastewater treatment system was investigated by denaturing gradient gel electrophoresis (DGGE) and in situ hybridization. Sludges were collected from three biological reactors (aerobic, oxic, and anoxic tanks) at the M was...

박테리아 군집을 해석하는 방법은? | 박테리아 군집을 해석하는 방법으로 FISH (fluorescent in situ hybridization)와 DGGE (denaturing gradient gel electrophoresis) 기법과 같은 분자유전학적 방법들이 최근까지 많이 이용되고 있다 [10-14]. 이러한 기법들은 박테리아 배양이 필요치 않는 비배양적인 방법으로 박테리아 군집의 시간·공간적 변화를 in situ 상태로 파악하는 데에 효과적이다[15,16]. | |

산업 폐수의 특징은? | 생물학적 처리공정은 일반적으로 물리·화학적 처리공정들에 비해 많은 장점들을 가지지만 오염물질 농도 부하, 수온, pH 및 용존 산소 등과 같은 유입수의 성상 변화에 매우 민감하기 때문에 처리효율에 많은 영향을 받는다 [17]. 특히, 피혁 폐수와 같은 산업 폐수의 경우는 중금속 등을 포함한 다양한 생물학적 독성 유발물질들이 함유되어 있어 유입수의 성상 변화는 생물학적 처리조의 운전효율에 많은 영향을 미친다 [18,19]. 따라서 생물학적 처리공정에서는 실제 현장에서의 효율적인 처리공정의 설계와 운영을 위하여 폐수의 성상변화에 따라 형성되는 박테리아 군집의 구조와 밀도를 파악하는 연구가 매우 중요하다. |
