“…In contrast, Crenarchaeota have been either undetected (Matyugina et al 2018) or at very low levels (Patricia et al 2018) in other soda lakes. Similar to levels observed in LGL, Euryarchaeota (35.15%) was the most abundant phylum in soda lakes of the Badain Jaran Desert (Banda et al 2019). Nevertheless, the overall microbial diversity in LGL was relatively higher than observed in other studies, and the unique hydrochemical characteristics of LGL may be an important factor contributing to this high diversity and unique microbial community structure.…”

“…The relative abundance of Proteobacteria was 29.5% in Lonar Lake (India) (Paul et al 2015), which is signi cantly lower than observed in LGL and also in the Soda Lake of Inner Mongolia (Namsaraev et al 2015). In addition, the abundances of some bacterial groups were lower than observed in LGL, including for the Bacteroidetes (8.25%) and Planctomycetes (6.8%) (Banda et al 2019). Planctomycetes and Acidobacteria are rarely observed in other soda lakes (Namsaraev et al 2015;Aguirre-Garrido et al 2016).…”

“…Na 2 CO 3 -type lakes are exceptional among aquatic ecosystems because they simultaneously exhibit high productivity rates and high pH (9.5-11.0) (Banda et al 2019;Paul et al 2015). The lakes are naturally occurring alkaline environments that contain high concentrations of sodium carbonate due to evaporative concentration in addition to high concentrations of other salts that can also accumulate (especially sodium chloride), leading to the formation of alkaline saline lakes (Namsaraev et al 2015).…”

Langaco Lake (LGL) is a strong Na2CO3-type lake that sits at an altitude of 4,548 m in the Qinghai-Tibet Plateau of China. LGL exhibits unique hydrochemical characteristics among Na2CO3-type lakes, but little is known about the microbial diversity of LGL and their interactions with environmental factors. Here, high-throughput sequencing of 16S rRNA genes revealed that LGL bacterial diversity comprised 327 genera in 24 phyla (4,871 operational taxonomic units [OTUs]; Shannon index values of 5.20–6.07) that represented significantly higher diversity than that of Archaea (eight phyla and 29 genera comprising 1,008 OTUs; Shannon index values of 2.98–3.30). The bacterial communities were dominated by Proteobacteria (42.79–53.70% relative abundances), followed by Bacteroidetes (11.13–15.18%), Planctomycetes (4.20–12.82%), Acidobacteria (5.91–9.50%), Actinobacteria (2.60–5.80%), and Verrucomicrobia (2.11–4.08%). Further, archaeal communities were dominated by Crenarchaeota (35.97–58.29%), Euryarchaeota (33.02–39.89%), and Woesearchaeota (6.50–21.57%). The dominant bacterial genus was Thiobacillus (8.92–16.78%), whose abundances were most correlated with total phosphorus (TP), pH, CO32− concentrations, and temperature. The most abundant archaeal genus was Methanoregula (21.40–28.29%), whose abundances were most highly correlated with TOC and TS in addition to the concentrations of K+, and Na+. Taken together, these results provide valuable insights towards a more comprehensive understanding of microbial diversity in these unique carbonate alkaline environments, in addition to a better understanding of microbial resources in the Qinghai-Tibet Plateau.

“…The high abundance ratios of Colwelliaceae, Chromatiaceae and Alteromonadaceae observed in high salinity S7 may be attributed to their sensitivity to salinity (Fig. 3c), proving that they may belong to marine bacterium (Kwak et al 2012;Methé et al 2005;Pfennig Trüper 1981) and they may have "exclude salt" mechanisms such as osmotic balance and prevent dry (Banda et al 2020). In this adaptation, the microorganism synthesizes the corresponding solute to help stabilize the cell membrane structure.…”

“…Our data confirm that certain bacterial groups are strongly correlated with salinity. The number of genes in low-salinity loci was higher than that in high-salinity loci, and Banda et al (2020) had pointed out that species diversity would decrease in high-salinity environments. We first screened out bacterial taxa that were strongly correlated with salinity and discussed their relative abundance differences.…”

Due to the inflow of meltwater from the Midre Lovénbreen glacier upstream of Kongsfjorden, the salinity of Kongsfjorden increases from the estuary to the interior of the fjord. Our goal was to determine which bacterial taxa and metabolism-related gene abundance were affected by changes in salinity, and whether salinity is correlated with genes related to nitrogen and sulfur cycling in fjord ecosystem using metagenomic analysis. Our data indicate that changes in salinity may affect some bacterial taxa, such as the relative abundance of Alphaproteobacteria and Deltaproteobacteria is higher at high salinity sites, while the relative abundance of Gammaproteobacteria and Betaproteobacteria is more dominant at low salinity sites. In addition, the relative abundance of some bacteria at the high and low salinity sites was different at the family level. For example, Rhodobacteraceae, Pseudoalteromonadaceae, Flavobacteriaceae, Vibrionaceae at the high salinity site Colwelliaceae, Chromatiaceae and Alteromonadaceae at the low salinity site are affected by salinity. In terms of functional gene diversity, our study proved that salinity could affect the relative abundance of related genes by affecting the metabolic mechanism of microorganisms. In addition to salinity, functional attributes of microorganisms themselves were also important factors affecting the relative abundance of metabolism-related genes. In addition, salinity has a certain effect on the relative abundance of genes related to nitrogen and sulfur cycling.
