应用拟杆菌作为水体粪源污染指示菌的研究进展

Review and Current Perspective on Using Bacteroides as A Fecal Source Indicator in Polluted Waterbodies

粪源污染是水环境安全的重要威胁。传统的指示微生物在水体粪源检测中存在较多局限性,难以准确溯源水体所受粪源污染。拟杆菌属微生物因其具有在人畜肠道中的绝对数量优势和突出的粪源指示作用等优点,在粪源污染监测中日渐受到重视。该文阐述了拟杆菌作为指示微生物在应用于示踪水体粪源污染时的优势,并针对水环境中拟杆菌的检测方法及其在受污水体中指示粪源污染的应用进行了概述。

It is well documented that fecal contamination in waterbodies is a major threat to water environmental safety.There are many limitations and difficulties to use traditional fecal indicator organisms for monitoring fecal contamination to accurately track the source of the fecal contamination in water.Bacteroides is an increasingly used method to determine the fecal contamination in waterbodies,for the advantage of their numerical superiority in human and animal intestinal microbes and the superior role of fecal source indicator.This paper introduced the facilities of Bacteroides used as indicator organism in the fecal pollution tracing,the methods of Bacteroides detection and its application in tracing fecal contamination were all present.
