  • Four new halophilic archaeal strains (YCN1, YCN58, LT38, LT62) were discovered in China’s Yuncheng Salt Lake and Tarim Basin.
  • Phylogenetic analysis showed that these strains are closely related to existing species in the Halobacterium, Natronomonas, Halorientalis, and Halobellus genera, but they meet the criteria for being classified as new species due to distinct characteristics.
  • The newly proposed species are named Halobacterium yunchengense, Natronomonas amylolytica, Halorientalis halophila, and Halobellus salinisoli based on their genetic and phenotypic differences.

Article Abstract

Four halophilic archaeal strains YCN1, YCN58, LT38, and LT62 were isolated from Yuncheng Salt Lake (Shanxi, China) and Tarim Basin (Xinjiang, China), respectively. Phylogenetic and phylogenomic analyses showed that these four strains tightly cluster with related species of Halobacterium, Natronomonas, Halorientalis, and Halobellus, respectively. The AAI, ANI, and dDDH values between these four strains and their related species of respective genera were lower than the proposed threshold values for species delineation. Strains YCN1, YCN58, LT38, and LT62 could be differentiated from the current species of Halobacterium, Natronomonas, Halorientalis, and Halobellus, respectively, based on the comparison of diverse phenotypic characteristics. The polar lipid profiles of these four strains were closely similar to those of respective relatives within the genera Halobacterium, Natronomonas, Halorientalis, and Halobellus, respectively. The phenotypic, phylogenetic, and genome-based analyses indicated that strains YCN1, YCN58, LT38, and LT62 represent respective novel species within the genera Halobacterium, Natronomonas, Halorentalis, and Halobellus, for which the names Halobacterium yunchengense sp. nov., Natronomonas amylolytica sp. nov., Halorientalis halophila sp. nov., and Halobellus salinisoli sp. nov. are proposed, respectively.

The cell membrane of Halobacterium salinarum contains a retinal-binding photoreceptor, sensory rhodopsin II (HsSRII), coupled with its cognate transducer (HsHtrII), allowing repellent phototaxis behavior for shorter wavelength light. Previous studies on SRII from Natronomonas pharaonis (NpSRII) pointed out the importance of the hydrogen bonding interaction between Thr204 and Tyr174 in signal transfer from SRII to HtrII. Here, we investigated the effect on phototactic function by replacing residues in HsSRII corresponding to Thr204 and Tyr174 .

Beyond Archaea: The Table Salt Bacteriome.

Front Microbiol

October 2021

Institute for Integrative Systems Biology (I2SysBio), Universitat de València-CSIC, Paterna, Spain.

Commercial table salt is a condiment with food preservative properties by decreasing water activity and increasing osmotic pressure. Salt is also a source of halophilic bacteria and archaea. In the present research, the diversity of halotolerant and halophilic microorganisms was studied in six commercial table salts by culture-dependent and culture-independent techniques.

Prokaryotic communities and physico-chemical characteristics of 30 brine samples from the thalassohaline Tuz Lake (Salt Lake), Deep Zone, Kayacik, Kaldirim, and Yavsan salterns (Turkey) were analyzed using 16S rRNA amplicon sequencing and standard methods, respectively. (98.41% of reads) was found to dominate in these habitats in contrast to the domain (1.

  • The study analyzed microbial diversity in the Siridao solar salterns of Goa, India, during two salt harvesting phases using high-throughput sequencing of 16S rRNA genes.
  • It found that Archaea shifted from sediments to brine while Bacteria moved in the opposite direction as salinity increased, with Archaea remaining prevalent even at lower salinity levels.
  • The research concluded that Archaea are more resilient to salinity changes than Bacteria, as many bacterial groups were more phase-specific and sensitive to these fluctuations.
