“…Bishav et al observed that such variations in the Great Salt Lake's northern and southern regions resulted in distinct species diversity [13]. The diverse microbial communities in the Plitvice lakes were linked to unique network ecosystems formed by varying salinity across different landforms [14]. This suggests that salinity differences within the same region may create a unique barrier affecting microbial diversity.…”

The Dong Taijinar (DT) and Xi Taijinar (XT) Salt Lakes have been extensively researched for their mineral richness. However, the composition and distribution of their microbial communities are still poorly known. In this study, we employed metagenomic sequencing to explore the diversity and potential functions of the microbial populations in DT and XT. Our findings indicate that the salinity levels in DT (332.18–358.30 g/L) were tenfold higher than in XT (20.09–36.83 g/L). Notably, archaea dominated the DT domain at 96.16%, while bacteria prevailed in XT at 93.09%. In DT, the bacterial community comprised 33 phyla and 1717 genera, with Marinobacter emerging as the dominant genus, showing a positive correlation with the total phosphorus content. The archaeal community in DT included four main phyla and 153 genera. The most abundant genera were Natronomonas (24.61%) and Halorubrum (23.69%), which had a strong positive correlation with the concentrations of Na+, Ca2+, and Cl−. Conversely, XT hosted 33 phyla and 1906 bacterial genera, with Loktanella as the dominant genus. The archaeal taxonomy in XT encompassed four phyla and 149 genera. In both salt lakes, Proteobacteria and Euryarchaeota were the most abundant bacterial and archaeal phyla, respectively. Our analysis of the halophilic mechanisms of these microorganisms suggests that the bacteria in XT tend to synthesize compatible solutes, whereas the archaea in DT adopt a ‘salt-in’ strategy, integrating salt into their cellular machinery to cope with the high-salinity environment.

“…Bishav et al found that the difference in salinity between the northern and southern regions of the hypersaline Great Salt Lake led to species diversity (14). Plitvice lakes with rich microbial communities were attributed to rare network ecosystems of varying salinity composed of several different landforms (15). Perhaps the difference in microbial diversity due to different salinities in the same area is a unique barrier system.…”

The Dong Taijinar Salt Lake (DT) and Xi Taijinar Salt Lake (XT) have been widely studied as mineral-rich areas. However, little is known about the composition and distribution of the microbial communities in these two lakes. In this study, metagenomics sequencing was used to analyze the diversity and potential functions of the microbial communities in DT and XT. According to our report, the salinity of DT (332.18–358.30 g/L) was 10 times higher than that of XT (20.09–36.83 g/L). Interestingly, the dominant domain in DT was Archaea (96.16%), while that in XT was Bacteria (93.09%). The distribution of Bacteria in the DT revealed 33 phyla and 1717 genera. The dominant genus in DT was Marinobacillus, which was positively correlated with total phosphorus content. There were four main phyla and 153 genera identified in the Archaea of DT. The most abundant Archaea genera in DT were Natronomonas (24.61%) and Halorubrum (23.69%), which were mainly positively correlated with the Na+, Ca2+, and Cl− contents. Similarly, there were 33 phyla and 1906 genera of Bacteria in XT, and Loktanella was the dominant genus. The archaeal taxonomy in XT mainly included four phyla and 149 genera. Proteobacteria and Euryarchaeota were the most abundant bacterial and archaeal phyla in the two salt lakes. Analysis of the halophilic mechanisms of the microorganisms identified in these two salt lakes revealed that the Bacteria in XT preferred to synthesize compatible solutes, whereas the Archaea in DT preferred a "salt-in" adaptation strategy in salt-stressed environments.
