Abstract

This review inquired the recently applied molecular biological and biochemical methods analyzing the microbial community structure of groundwater and, as a result, summarized the functional or taxonomic groups of active microorganisms with major contaminants in groundwater. The development of gene amplification through PCR has been possible to figure out microbial population and identification. Active microbial community structures have been analyzed using a variety of fingerprinting techniques such as DGGE, SSCP, RISA, and microarray and fatty acid analyses such as PLFA and FAME, and the activity of a specific strain has been examined using FISH. Also, this review included the dominant microflora in groundwater contaminated with fuel components such as n-alkanes, BTEX, MTBE, and ethanol and chlorinated compounds such as TCE, PCE, PCB, CE, carbon tetrachloride, and chlorobenzene.

최근에 적용된 지하수 미생물의 군집구조를 밝히는 분자생물학적 및 생화학적 방법들에 대해서 알아보았고 그 결과로서 지하수의 주요 오염물질에 따른 활성화된 미생물군집들이 무엇인지를 밝힌 연구논문들을 종합하여 정리하였다. PCR에 의한 유전자 증폭기술의 발달로 배양 없이 미생물 종류와 개체군을 파악할 수 있게 되었고 각종 finger-printing 방법 (DGGE, SSCP, RISA, microarray) 과 지방산분석법 (PLFA/FAME)을 이용하여 활성화 된 미생물군집구조를 분석하였으며 FISH 등의 방법으로 특정균의 활성도를 알아본 사례들을 조사하였다. 대표적인 지하수오염물질인 유류성분 (n-alkanes, BTEX, MTBE, ethanol)과 염소계 용매 (TCE, PCE, PCB, CE, carbon tetrachloride, chloro-benzene) 등으로 오염되었을 때 우점하는 지하수 미생물상에 대해 보고된 내용을 포함하였다.
