Successive microbes in solar salt ponds are essential since it is well correlated with the quality of salt produced. This research aimed to analyze the microbial diversity of the solar salt ponds in Indonesia, which use high-density polyethylene (HDPE) in the ponds. There are two systems, i.e., an integrated open system (In-system) and a closed system (Tt-system). The In-system uses seawater while the Tt-system uses seawater from the saline artesian well. Results showed that the In-system had richer microbes than the Tt-system. Both systems shared similar halophilic microbes profile. Ponds with low salinity (3-4 Be) had very low archaea, i.e., 0.2% and 0.7% for the In-system and Tt-system, respectively, and were dominantly inhabited by phylum Proteobacteria. In the pond with high salinity, i.e., 25 Be, both systems were dominated by the phylum Euryarchaeota, family Halobacteriaceae, and genera Halorubrum was dominantly found in In25 ponds and Tt25 ponds. Even though the two systems use the same parent seawater, i.e., the Java Sea and share similar microbial composition at the phylum level, we found the dominance identified microbes in both systems were different.

印度尼西亚西爪哇因德拉马尤两个极地盐场系统嗜盐菌的比较多样性分析

太阳盐池中的连续微生物是必不可少的，因为它与所生产盐的质量密切相关。这项研究旨在分析印度尼西亚太阳能盐池的微生物多样性，这些盐池在池塘中使用高密度聚乙烯 (HDPE)。有两个系统，即集成的开放系统（In-system）和封闭系统（Tt-system）。In-system 使用海水，而 Tt-system 使用来自盐水自流井的海水。结果表明，In-system 比 Tt-system 具有更丰富的微生物。两个系统共享相似的嗜盐微生物特征。低盐度 (3-4 Be) 的池塘中古菌含量非常低，即 In-system 和 Tt-system 分别为 0.2% 和 0.7%，并且主要由变形菌门居住。在高盐度的池塘中，即 25 Be，两个系统均以 Euryarchaeota 门、Halobacteriaceae 科为主，而 Halorubrum 属在 In25 池塘和 Tt25 池塘中占优势。尽管这两个系统使用相同的母海水，即爪哇海，并且在门水平上共享相似的微生物组成，但我们发现两个系统中确定的微生物的优势是不同的。
