Summary: Lake Urmia in Iran is a hypersaline environment with a salinity of about 27%. Metagenomic analysis revealed that the microbial community in the lake is dominated by Haloferacaceae family (69.8%), mainly Haloquadratum (59.3%) and Halonotius (9.1%). The bacterial community is mainly composed of Salinibacter ruber (23.3%). Genomic variation analysis showed a high level of SNVs and insertions in Lake Urmia's community, possibly due to transformation caused by the extreme conditions and high ionic concentrations.

Summary: This article explores the diversity, functions, and evolution of bacteria and archaea inhabiting Earth's major extreme environments. Marker gene surveys and omics studies have played a crucial role in revealing the structure, function, and evolution of extremophile microbial communities, uncovering vast uncultured microbial diversity and the predominance of archaea in extreme conditions.

Summary: Research using DNA metabarcoding techniques combined with hydrochemical analyses investigated microbial patterns in five hypersaline lakes at Rottnest Island, revealing lake-driven aquatic microbial communities characterized by moderately to extremely halophilic groups, with TDS and alkalinity being influential parameters. DNA metabarcoding allows rapid and reliable ecological assessment of hypersaline aquatic microbial communities, showing potential for further study across different hypersaline lakes in various seasons.

Summary: The use of hypersaline electrolytes can enhance the efficiency of microbial fuel cells, but the bottleneck of O-2 reducing cathodes still needs to be addressed. By designing efficient halotolerant microbial cathodes, especially focusing on Gammaproteobacteria strains related to Thiohalobacter thiocyanaticus, this issue can be overcome.

Summary: The microbial diversity and metabolome profile of a unique hypersaline elastic microbial mat from Cuatro Cienegas Basin in the Chihuahuan Desert of Mexico were evaluated. The microbial diversity was assessed through NGS-based ITS and 16S rDNA gene sequencing, revealing a low number of abundant taxa and a more diverse rare biosphere. Furthermore, each sample showed a distinct metabolome profile with potentially biologically relevant compounds.

Summary: Microbial anodes and oxygen reducing microbial cathodes were designed separately and then combined to form two-compartment microbial fuel cells. The MFCs produced significant power density in a hypersaline medium, with Desulfuromonas sp. identified as key species of the anodes. The efficiency of the cathodes was linked to the development of a redox system centered at a certain voltage and the presence of specific phylogenetically linked bacteria. Comparing different MFCs' performances suggested that maintaining longer polarization at a certain voltage could promote growth of specific bacteria on the cathode and enhance MFC performance.

Summary: Hamelin Pool in Western Australia is a modern microbial carbonate factory, with the largest living marine stromatolite system, producing a significant amount of microbial sediments annually. Erosion and degradation of weakly lithified microbial mats in the pool lead to the production of sand-sized micritic grains, contributing to nearly a quarter of the total sediment. These modern examples provide valuable insight for identifying sedimentary deposits of microbial origin in the geologic record.

Summary: Lost Hammer Spring in Canada's Nunavut region is one of the coldest and saltiest terrestrial springs discovered to date. A multi-omics approach revealed a rare surface terrestrial habitat supporting an active microbial community, indicating the potential for similar microbial life to survive in Mars-like environments.

Summary: Hypersaline waters and glacial ice are inhospitable environments, but they support diverse microbial communities, including extremotolerant and extremophilic fungi. These fungi have unique adaptations to survive in these extreme environments, such as balancing osmotic pressure, stabilizing cell membranes, and neutralizing oxidative stress. Further investigation is needed to understand their role in climate-affected environments, decipher their stress resistance mechanisms, and explore their biotechnological potential.

Summary: This study investigated the diversity and community structure of endophytic and rhizospheric bacteria associated with three halophytes. The results showed that rhizospheric bacterial richness and diversity were higher than for endophytic bacteria. Actinobacteria, Firmicutes, Bacteroidetes and Proteobacteria were the dominant bacterial phyla. This research provides important insights into the ecological adaptation mechanism of halophytes.

Summary: This study investigated the microbial mat of the Laguna Negra lake to understand its vertical structure and strategies for thriving under environmental stressors. The results showed that the top layer of the mat exhibited remarkable UV-tolerance, likely achieved through the presence of Deinococcus-Thermus and deinoxanthin. This detailed study provides insights into the microbial community's strategies to cope with high UV radiation and hypersalinity in high-altitude lakes.

Summary: Studying geothermal pools in Iceland reveals that volcanic processes play a significant role in controlling the geochemistry and microbial community structure. The pools in Kerlingarfjoll and Kverkfjoll exhibit different water chemistry, sediment composition, and dominant microbial metabolisms, influenced by volcanic processes and water input from glaciers. This research provides insights into the potential habitability of relic hydrothermal systems on Mars and their significance in supporting chemolithotrophic life.

Summary: The microbial community of acid mine drainage (AMD) shows significant physicochemical variations and microbial diversity across different mining areas, with Mg2+ and SO42- being the predominant factors shaping microbial structure. Functional redundancy and diverse metabolic potentials are identified in polymetallic AMD compared to copper AMD. Physicochemical parameters such as Mg2+, SO42-, Ca2+, temperature, and Fe2+ drive iron, sulfur, nitrogen, and carbon metabolisms in the microbial communities, distinguishing microbial profiles between copper mine AMD and polymetallic AMD.

Summary: The molecular diversity of two hypersaline microbial mats from lakes in Chile was compared using WGS sequencing, showing differences in taxonomic diversity but similarity in functional roles. Despite differences at the taxonomic level, functionally the two mats were similar, with different organisms potentially fulfilling similar roles. Mat from Brava was more rich and diverse, while Tebenquiche mats showed lower diversity but increased abundance and variety of rhodopsin genes.

Summary: Halophilic Archaea are widely distributed in hypersaline environments, with the archaeal communities in the Qaidam Basin of China showing diversity and dominance of specific genera. The taxonomic distributions across sample sites were most correlated with salinity and pH levels, indicating potential interspecies interactions among the halophilic archaeal taxa. The study identified five network clusters reflective of these interactions, with distinct genera inconsistently distributed across samples.

Summary: The literature on ocular microbiome has significantly expanded in the past decade, with the development of 16S rRNA sequencing enabling better characterization of bacterial communities in health and ocular disease. Efforts should be continued to explore the interaction between microbiome and key factors such as age, comorbidities, and contact lens usage for improved control of sight-threatening complications.
