Microbial communities inhabiting hypersaline wetlands, well adapted to the environmental fluctuations due flooding and desiccation events, play a key role in biogeochemical cycles, ensuring ecosystem service. To better understand functioning, we studied soil microbial of Salineta wetland (NE Spain) dry wet seasons three different landscape stations representing situations characteristic ephemeral saline lakes: S1 usually submerged, S2 intermittently flooded, S3 with halophytes. community composition was determined according redox layers by 16S rRNA gene barcoding. We observed reversed gradient, negative at surface positive depth, which identified PERMANOVA as main factor explaining distribution. The Pseudomonadota, Gemmatimonadota, Bacteroidota, Desulfobacterota, Halobacteriota phyla were dominant all stations. Linear discriminant analysis effect size (LEfSe) revealed that upper layer characterized predominance operational taxonomic units (OTUs) affiliated strictly or facultative anaerobic halophilic bacteria archaea while subsurface dominated an OTU Roseibaca, aerobic alkali-tolerant bacterium. In addition, potential functional capabilities, inferred PICRUSt2 analysis, involved carbon, nitrogen, sulfur cycles similar samples, irrespective stratification, suggesting redundancy. Our findings show changes water conditions, represent useful information for biomonitoring management these wetlands whose extreme aridity salinity conditions are exposed irreversible human activities.

The class Halobacteria is one of the most diverse groups within Euryarchaeota phylum, whose members are ubiquitously distributed in hypersaline environments, where they often constitute major population. Here, we report discovery and isolation a new halophilic archaeon, strain F3-133T exhibiting ≤86.3% 16S rRNA gene identity to any previously cultivated and, thus, representing order. Analysis available amplicon metagenomic data sets showed that isolate represents an abundant group intermediate-to-high salinity ecosystems widely across world. presents streamlined genome, which probably accounts for its ecological success nature fastidious growth culture. predominant osmoprotection mechanism appears be typical salt-in strategy used by other haloarchaea. Furthermore, genome contains complete set nucleotide monophosphate degradation pathway through archaeal RuBisCO, being first archaea representatives reported code this enzyme. Genomic comparisons with described phylum were consistent supporting our novel order propose names Halorutilales ord. nov., Halorutilaceae fam. Halorutilus gen. nov. salinus sp. IMPORTANCE salinus, order, family, genus, species clearly enables insights into microbial dark matter, expanding current taxonomical knowledge archaea. in-depth comparative genomic analysis performed on taxon revealed known examples representative coding RuBisCO ecologically successful explaining previous non-isolation. Altogether, research brings light understanding physiology members, their distribution, capacity thrive environments.

Hypersaline soils are extreme environments that have received little attention until the last few years. Their halophilic prokaryotic population seems to be more diverse than those of well-known aquatic systems. Among inhabitants, representatives family Balneolaceae (phylum Balneolota ) been described abundant, but very members isolated and characterized date. This comprises genera Aliifodinibius Fodinibius along with four others. A novel strain, designated 1BSP15-2V2 T , has from hypersaline located in Odiel Saltmarshes Natural Area (Southwest Spain), which appears represent a new species related genus . However, comparative genomic analyses revealed belong single genus, hence we propose reclassification into Fodinibius, was first described. The strain is thus as salsisoli sp. nov., (=CCM 9117 = CECT 30246 type strain. other closely ones show abundant recruitment within 80–90% identity range when searched against several soil metagenomic databases investigated. might suggest there still uncultured, yet this present these environments. In-depth in-silico analysis metabolism showed biotin biosynthesis pathway genomes could entail major implications their community role providing vitamin organisms depend on an exogenous source nutrient.
