Strain Llam7 was isolated from microbial mat samples from the hypersaline lake Salar de Llamará, located in Taracapá region in the hyper-arid core of the Atacama Desert (Chile). Phenotypic, chemotaxonomic and genomic traits were studied. Phylogenetic analyses based on 16S rRNA gene sequences assigned the strain to the family with affiliation to the genera and . Major fatty acids were Cω8, iso-C, iso-C and anteiso-C. The cell walls contained -diaminopimelic acid and ll-2,6 diaminopimelic acid (ll-DAP), while major whole-cell sugars were glucose, mannose, xylose and ribose. The major menaquinones were MK-9(H) and MK-9(H). As polar lipids phosphatidylglycerol, phosphatidylethanolamine, diphosphatidylglycerol and several unidentified lipids, i.e. two glycolipids, one aminolipid, three phospholipids, one aminoglycolipid and one phosphoglycolipid, were detected. Genome sequencing revealed a genome size of 6.894 Mb and a DNA G+C content of 71.4 mol%. Phylogenetic analyses with complete genome sequences positioned strain Llam7 within the family forming a distinct cluster with (former ) DSM 45730. This cluster is related to KJ-029, NA12, and LHW63014 as well as to all members of the former genera and , which were re-classified as members of the genus , forming a clade distinct from the genus . Pairwise whole genome average nucleotide identity (ANI) values, digital DNA-DNA hybridization (dDDH) values, the presence of the diamino acid ll-DAP, and the composition of whole sugars and polar lipids indicate that Llam7 represents a novel species, for which the name sp. nov. is proposed, with Llam7 (=DSM 109510,=LMG 31023) as the type strain.

Four novel halophilic archaeal strains CGA53, CG83, FCH27, and SEDH24 were isolated from a soda lake and two saline lakes in China, respectively. Strain CGA53 showed the highest 16S rRNA gene similarity (92.6%) to Salinilacihabitans rarus AD-4, and the other three strains were found to be related to Halalkalicoccus species with similarities of 97.

The composition and source information of the aquatic dissolved organic matter (DOM) in the Daihai Lake, a typical saline lake at the ecologically fragile agro-pastoral area, were explored with three-dimensional excitation and emission matrix fluorescence (3DEEM), parallel factor analysis (PARAFAC), and fluorescence peaks (B, T, A, M, C, D, and N). Further, the relationship between aquatic DOM fluorescence characteristics and environmental factors were analyzed using correlation analysis in the Daihai Lake. The results showed that the water of Daihai was weakly alkaline, with high nutrient salt concentration and serious organic pollution.

Article Synopsis
  • - The study identifies a new diatom species from the highly alkaline Lake Van in Turkey, characterized through light and scanning electron microscopy on both wild and cultivated samples.
  • - Genome analysis revealed that the two monoclonal cultures have very similar DNA sequences with only a few mutations, particularly in the mitochondrial and plastid genomes, indicating some differences in protein coding genes.
  • - Phylogenetic analysis placed the new diatom species within the K clade, known for its diversity of species from hypersaline to freshwater environments.

Article Synopsis
  • Soda lakes, like Lake Magadi, have unique microbial communities affected by seasonal changes in water chemistry due to evaporation and flooding.
  • * Using 16S rRNA gene sequencing, researchers studied microbial diversity and structure in water and brine samples, finding that bacteria were more diverse and abundant than archaea, with variations across different months.
  • * Key factors affecting this diversity included temperature, pH, and various chemical parameters, with salinity and alkalinity identified as major influences on microbial composition.

Saline shallow lakes in arid and semi-arid regions frequently undergo drying episodes, leading to significant variations in salinity and water availability. Research on the impacts of salinity and drought on the structure and function of biofilms in hypersaline shallow lakes is limited. This study aimed to understand the potential changes of biofilms in playa-lake sediments during the drying process.
