| 摘 要： | 水体中微生物对环境的改变有着敏感的响应。16S rRNA基因克隆文库可以同时反映标本中的细菌种类和各种细菌的相对比例。本研究构建环境样品16S rRNA基因的克隆文库,解析长白山小天池入水口和长白瀑布下水潭两个典型水体样本中的细菌种属多样性特征,并探讨其与水体性质的关系。小天池文库共获得89条16S rRNA基因序列,分别属于10个类群,其中Betaproteobacteria是主要类群(占总数的23.6%)。长白瀑布文库共获得88条序列,分别属于8个类群,以Betaproteobacteria为主要类群(占总数的35.2%)。Bacteroidetes、Betaproteobacteria、Alphaproteobacteria和Gammaproteobacteria是两个样本共有的优势类群,而Deltaproteobacteria、Acidobacteria和Armatimonadetes只在小天池入水口处检出。长白瀑布水潭中的细菌群落多样性明显偏低,种群均匀度指数也较低,但两样本的地理距离极短,认为人类活动可能是导致这种差异的原因。

| Abstract: | Microorganisms in water can indicate changes in the environment with sensitive response. Through 16S rRNA clong library method, the authors can analyze the species of bacterial in samples, and know the relative proportion among all kinds of bacteria and etc. Therefore, this method has been widely applied to the environmental microbiology research. Through 16S rRNA clong library method, bacterial diversity characteristics and its relationship with the nature of waters from Xiaotianchi lake (water inletentry point) and Changbai waterfall (plunge pool) were analyzed. 89 gene sequences of 16S rRNA from Xiaotianchi lake were obtained, belonging to 10 groups. Among them, Betaproteobacteria is the major group dominating by 23.6%. 88 gene sequences of 16S rRNA from Changbai waterfall were obtained, belonging to 8 groups. Among them, Betaproteobacteria is the major group dominating by 35.2%. Bacteroidetes, Betaproteobacteria,Alphaproteobacteria and Gammaproteobacteria were the main bacteria groups in both of the two environments, while Deltaproteobacteria,Acidobacteria and Armatimonadetes were only detected from the water entry point of Xiaotianchi lake. Both the bacterial community diversity and species evenness index from the plunge pool of Changbai waterfall are lower than those from the water inlet of Xiaotianchi lake. The two sampling sites are not far apart with similar natural environment, but quite different on the level of human activities. The authors argue that human activities may be the cause of differences between both bacteria community diversity. |
