Sulfur related prokaryotes residing in hot spring present good opportunity for exploring the limitless possibilities of integral ecosystem processes. Metagenomic analysis further expands phylogenetic breadth these extraordinary sulfur (S) metabolizing microorganisms as well their complex metabolic networks and syntrophic interactions environmental biosystems. Through this study, we explored expanded microbial genetic repertoire with focus on S cycling genes through metagenomic contaminated spring, located at Northern Himalayas. The revealed rich diversity consortia established roles such Pseudomonas, Thioalkalivibrio, Desulfovibrio, Desulfobulbaceae (Proteobacteria). major gene families inferred to be abundant across mat, sediment, water were assigned Proteobacteria reflected from reads per kilobase (RPKs) categorized into translation ribosomal structure biogenesis. An sequence similarity showed conserved pattern both dsrAB (n = 178) retrieved all metagenomes while other disproportionation proteins diverged due different structural chemical substrates. oxidizing bacteria (SOB) sulfate reducing (SRB) (r)dsrAB suggests it an important adaptation fitness site. Here, (i) oxidative reductive dsr evolutionary time-scale phylogeny proved that earliest (but not first) belong anaerobic Thiobacillus (rdsr) oxidizers, also confirm (ii) SRBs belongs δ-Proteobacteria occurring independent lateral transfer (LGT) few novel lineages. Further, prediction unassigned DsrAB confirmed relatedness species Desulfovibrio (TM score 0.86, 0.98, 0.96) Archaeoglobus fulgidus 0.97, 0.98). We proposed might provide basis studying evolution horizontal biogeochemical cycling.

Over the course of last 20 years, numerous studies have identified benefits thermal waters on different skin conditions. Consequently, several investigations been carried out their effects skin, which are linked to chemical composition, and, recently, scientists turned attention role spring’s microbiota, named “hydrobiome”, regarding these therapeutic effects. At same time, development cosmetics based pre, pro, and postbiotics has reached great relevance research is increasing every day. This review gathers information biological diversity spring potential use in obtaining compounds, metabolites, or bacterial extracts for dermocosmetics as active ingredients. These bioactive compounds able improve dermatological diseases such atopic dermatitis rosacea ameliorate pruritus xerosis; moreover, they can increase protection against UV exposure, strengthen barrier function, maintain good homeostasis defenses, repair damaged promote wound healing, condition, reduce uneven pigmentation, prevent aging. From a future perspective, fruitful cooperation among researchers, hydrologists, spa centers, cosmetic industries will drive this sector toward better understanding hydrobiome healthy consider inclusion derivatives (in form fermenters, lysates, extracts, etc.) dermocosmetic formulations. Therefore, being aware care applications, prospects substances derived from it formulations promising.

Cyanobacteria thrive in diverse environments. However, questions remain about possible growth limitations ancient environmental conditions. As a single genus, the Thermosynechococcus are cosmopolitan and live chemically habitats. To understand genetic basis for this, we compared protein coding component of genomes. Supplementing known diversity Thermosynechococcus, report draft metagenome-assembled genomes two recovered from ferrous carbonate hot springs Japan. We find that as is genomically conserved, having small pan-genome with few accessory genes per individual strain well unique to genus. Furthermore, by comparing orthologous groups, including an analysis encoding proteins iron related function (uptake, storage or utilization), no clear differences content, adaptive mechanisms could be detected between genus members, despite range environments they inhabit. Overall, our results highlight seemingly innate ability inhabit habitats without undergone substantial genomic adaptation accommodate this. The finding both high recognizable perspective proteome has implications understanding thermophily within this clade, also tolerance cyanobacteria on early Earth. conserved core genome may indicative allopatric lifestyle—or reduced complexity spring relative other

Abstract. Marine sedimentation rate and bottom-water O2 concentration control organic carbon remineralization sequestration across continental margins, but whether how they shape microbiome architecture (the ultimate effector of all biogeochemical phenomena) shelf slope sediments is still unclear. Here we reveal distinct structures functions, amidst comparable pore fluid chemistries, along 300 cm sediment horizons underlying the seasonal (shallow coastal; water depth: 31 m) perennial (deep sea; depths: 530 580 oxygen minimum zones (OMZs) Arabian Sea, situated western Indian margin. The sedimentary geomicrobiology was elucidated by analyzing metagenomes, metatranscriptomes, enrichment cultures, depositional rates measured via radiocarbon lead excess dating; findings were then evaluated in light other geochemical data available for cores. Along perennial-OMZ cores, microbial communities dominated Gammaproteobacteria Alphaproteobacteria, seasonal-OMZ core Euryarchaeota Firmicutes. As a signature, cryptic methane production–consumption cycle found to operate near surface, within sulfate reduction zone; overall diversity, as well relative abundances anaerobes requiring simple fatty acids (methanogens, anaerobic oxidizers, reducers, acetogens), peaked topmost layer declined synchronized fluctuations until sulfate–methane transition zone reached. profile completely reversed horizon.

Fog supports an increase in airborne microbial loading by providing water with nutrients and protecting it from harmful incoming solar radiation. To improve our present understanding of fog-induced alteration atmospheric community, a study was conducted during 1 to 14 January 2021 for continuous investigation bacteria over rural site, Arthauli (25.95°N, 85.10°E), central Indo-Gangetic Plain (IGP) India.

Hot springs are some of the most special environments on Earth. Many prokaryotic and eukaryotic microbes have been found to live in this environment. The Himalayan geothermal belt (HGB) has numerous hot spread across area. Comprehensive research using molecular techniques investigate microorganisms is still lacking; investigating composition diversity such as protists spring ecosystems will not only provide critical information adaptations extreme conditions, but could also give valuable contributions global knowledge biogeographic diversity. In study, we used high-throughput sequencing illuminate pattern protist communities 41 HGB Tibetan Plateau. A total 1238 amplicon sequence variants (ASVs) were identified HGB. general, Cercozoa was phylum with highest richness, Bacillariophyta relative abundance protists. Based occurrence ASVs, them rare. high variation may be due different environmental conditions these springs. Temperature, salinity, pH important factors that affect surface sediments summary, study provides first comprehensive facilitates our understanding adaptation habitats.
