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. DMSP concentrations from phytoplankton and DMS and dissolved DMSP concentrations in the water samples are shown. There is a negative correlation between the abundance of DMSO-respiring bacteria and DMSP, there are many Marinobacter in the surface water.

3个盐湖盐湖中存在盐跃层的细菌群落结构不同，表明盐湖中存在大量未鉴定的细菌，具有丰富的生物多样性。8个淡水湖的细菌群落结构简单，如生活在极地海洋和麦克默多干河谷周围的雨水中的硫杆菌成为优势属。系统发育分析表明，这些生长在盐湖和淡水湖中的细菌是密切相关的属。显示了来自浮游植物和DMS的DMSP浓度以及水样中溶解的DMSP浓度。DMSO呼吸细菌的丰度与DMSP呈负相关，地表水中存在较多的海洋杆菌。
