16S rRNA clone library analysis was used to examine the biodiversity and community structure in Antarctic salt and freshwater lakes. The bacterial community structures of salt lakes in which haloclines exist differed between these three salt lakes, indicating that there were many unidentified bacteria, and that they were rich in biodiversity. The bacterial communities of eight freshwater lakes formed a simple structure, such as Thiomicrospira sp., which inhabits the ocean in polar regions and fall water around McMurdo Dry Valleys, becomes the predominant genus. Phylogenetic analysis revealed that these bacteria growing in salt and freshwater lakes were closely related genera. These results suggested that these bacterial communities differed based on the salinity.

利用16 S rRNA克隆库分析来研究南极咸水湖和淡水湖的生物多样性和群落结构。盐跃层存在的盐湖细菌群落结构在这三个盐湖之间存在差异，表明存在许多未鉴定的细菌，具有丰富的生物多样性。八个淡水湖泊的细菌群落形成了一个简单的结构，如硫微螺旋菌，栖息在极地海洋和麦克默多干旱山谷周围的瀑布水，成为主要的属。系统发育分析表明，这些细菌生长在盐水和淡水湖泊密切相关的属。这些结果表明，这些细菌群落不同的盐度。
