Abstract Our understanding of the microbial diversity inhabiting hypersaline environments, here defined as containing >100–150 g/L salts, has greatly increased in past five years. Halophiles are found each three domains life. Many novel types have been cultivated, and metagenomics other cultivation-independent approaches revealed existence many previously unrecognized lineages. Syntrophic interactions between different phylogenetic lineages discovered, such symbiosis members archaeal class Halobacteria ‘ Candidatus Nanohalarchaeota’. Metagenomics techniques also shed light on biogeography halophiles, especially genera Salinibacter ( Bacteria ) Haloquadratum Halorubrum Archaea ). Exploration microbiome lakes led to discovery metabolism unknown occur at high salt concentrations. Studies environments with concentrations chaotropic ions magnesium, calcium, lithium refined our limits

Abstract The domain Archaea was initially characterized as extremophiles upon its proposal. Recent significant discoveries have redrawn our views of archaeal biology, encompassing the identification mesophilic groups, expansion diversity and metabolic capabilities, elucidation evolutionary relationships among archaea, bacteria, eukaryotes. are ubiquitous constitute a substantial fraction microbial biomass within sediments. Therefore, comprehending their ecological roles is paramount for understanding contributions to global geochemical cycles. In this review, we summarize archaea across various sediment ecosystems, from terrestrial inland deep‐sea environments, utilizing representative genomes supported by Genome Taxonomy Database, which encompasses habitats such hot springs, salt lakes, freshwater rivers, mangroves, estuaries, coastal regions, seafloor sediments, cold seeps, hydrothermal vents. Furthermore, integrate analyses with recent studies highlight potentials, novel enzymatic functions, related carbon, nitrogen, sulfur cycles different lineages. Finally, discuss research hotspots achievements in studies, while projecting future exploration directions. expanding capacities broadened perspective on tree life underscored critical impacts ecosystems.

Archaeal lipids, defining a primordial life domain alongside Bacteria and Eukarya, are distinguished by their unique glycerol-1-phosphate backbone ether-linked isoprenoid chains. Serving as critical geochemical biomarkers, archaeal lipids like glycerol dialkyl tetraethers (GDGTs) underpin paleoclimate proxies, while phylum-specific distributions illuminate phylogenetic divergence. Despite the maturity of Mass Spectrometry-based quantitative biomarkers—predominantly those with established structures—becoming well-established in research, systematic investigation natural products has notably lagged. This deficit manifests across three key dimensions: (1) Extraction methodology lacks universal protocols adapted to diverse taxa sample matrices. While comparative studies exist, theoretical frameworks guiding method selection remain underexplored. (2) Purification challenges persist due structures complex isomerization profiles hindering standardized separation protocols. (3) Most critically, structural characterization predominantly depends on decades-old foundational studies. However, existing reviews prioritize chemical structural, biosynthetic, applied aspects over analytical workflows. review addresses this gap adopting product chemistry perspective, integrating aspects: clarification applicable objects, scopes, methodological mechanisms various extraction technologies for encompassing both cultured environmental samples; elucidation principles underlying polar-gradient lipid fractionation processes, leveraging advanced chromatographic technologies; detailed exploration applications NMR resolving structures, specialized emphasis determining stereochemical configuration. By synthesizing six decades evolution, we establish comprehensive framework, from identification. integrated approach constructs paradigm analysis, bridging practical implementation.

The genus Haloarcula is one of the most extensively studied genera within class Halobacteria. In this study, analyses average nucleotide identity (ANI), amino acid (AAI), digital DNA–DNA hybridization (dDDH) values, and phylogenomic data indicated that “Haloarcula californiae” ATCC 33799 sinaiiensis” 33800 served as reference strains for marismortui. Furthermore, a halophilic archaeal strain, GH36T, isolated from inland Gahai Salt Lake in China, was subjected to comprehensive polyphasic taxonomic characterization. ANI, AAI, dDDH comparisons between strain GH36T other species were below established thresholds demarcation. Strain assigned novel based on phylogenetic, phylogenomic, comparative genomic analyses. Moreover, distinct phenotypic differences observed GH36T. primary phospholipids detected phosphatidylglycerol (PG), phosphate methyl ester (PGP-Me), sulfate (PGS), whereas principal glycolipids sulfated mannosyl glucosyl diether (S-DGD-1) (DGD-1). Accordingly, montana sp. nov. proposed accommodate (=CGMCC 1.62631T = MCCC 4K00122T).
