ABSTRACT We employed culture-dependent and -independent techniques to study microbial diversity in Lake Chaka, a unique hypersaline lake (32.5% salinity) northwest China. It is situated at 3,214 m above sea level dry climate. The average water depth 2 3 cm. Halophilic isolates were obtained from the water, halotolerant shallow sediment. exhibited resistance UV gamma radiation. Microbial abundance sediments ranged 10 8 cells/g water-sediment interface 7 sediment of 42 A major change bacterial...
Abstract Investigating microbial response to environmental variables is of great importance for understanding acclimatization and evolution in natural environments. However, little known about how communities responded factors (e.g. salinity, geographic distance) lake surface sediments the Qinghai-Tibetan Plateau (QTP). In this study, diversity community structure nine lakes on QTP were investigated by using Illumina Miseq sequencing technique resulting data statistically analyzed...
The Rehai and Ruidian geothermal fields, located in Tengchong County, Yunnan Province, China, host a variety of geochemically distinct hot springs. In this study, we report comprehensive, cultivation-independent census microbial communities 37 samples collected from these encompassing sites ranging temperature 55.1 to 93.6°C, pH 2.5 9.4, mineralogy silicates carbonates Ruidian. Richness was low all samples, with 21–123 species-level OTUs detected. bacterial phylum Aquificae or archaeal...
Previous investigations of the salinity effects on microbial community composition have largely been limited to dynamic estuaries and coastal solar salterns. In this study, mineralogy was studied by using a 900-cm sediment core collected from stable, inland hypersaline lake, Lake Chaka, Tibetan Plateau, north-western China. This core, spanning time 17,000 years, unique in that it possessed an entire range freshwater clays silty sands at bottom gypsum glauberite middle, halite top. Bacterial...
The Tibetan Plateau in Northwest China hosts a number of hot springs that represent biodiversity hotspot for thermophiles, yet their diversity and relationship to environmental conditions are poorly explored these habitats. In this study we investigated microbial community composition 13 with wide range temperatures (22.1–75°C) other geochemical by using the 16S rRNA gene pyrosequencing approach. Bacteria (108–1011 copy/g; 42 bacterial phyla) were more abundant far diverse than Archaea...
Abstract Several abundant but yet uncultivated bacterial groups exist in extreme iron- and sulfur-rich environments, the physiology, biodiversity, ecological roles of these bacteria remain a mystery. Here we retrieved four metagenome-assembled genomes (MAGs) from an artificial acid mine drainage (AMD) system, propose they belong to new deltaproteobacterial order, Candidatus Acidulodesulfobacterales. The distribution pattern Ca. Acidulodesulfobacterales AMDs across Southeast China correlated...

Recent experiment has unveiled an anomalously strong electron-electron attraction in one-dimensional copper-oxide chain Ba$_{2-x}$Sr$_x$CuO$_{3+\delta}$. While the near-neighbor electron $V$ extended Hubbard been examined recently, its effect model beyond remains unclear. We report a density-matrix renormalization group study of on long four-leg cylinders square lattice. find that can notably enhance long-distance superconducting correlations while simultaneously suppressing...
Soil sulfates are present in arid and hyperarid environments on Earth have been found to be abundant soils Mars. Examination of soil gypsum from the Atacama Desert, Chile, Mojave United States, Al‐Jafr Basin, Jordan, revealed endolithic cyanobacteria communities just below surface samples. Optical scanning electron microscope observations colonized layers indicated that unicellular Chroococcidiopsis is dominant cyanobacterium all studied communities. 16S rRNA gene analysis addition , a few...
The microbial diversity was investigated in sediments of six acidic to circumneutral hot springs (Temperature: 60-92 °C, pH 3.72-6.58) the Philippines using an integrated approach that included geochemistry and 16S rRNA gene pyrosequencing. Both bacterial archaeal abundances were lower high-temperature than moderate-temperature ones. Overall, community consisted sequence reads exhibited a high similarity (nucleotide identity > 92%) phyla Crenarchaeota, Euryarchaeota, unclassified Archaea....
A survey was carried out on the microbial community of 20 groundwater samples (4 low and 16 high arsenic groundwater) 19 sediments from three boreholes (two one boreholes) in a system located Hetao Basin, Inner Mongolia, using 454 pyrosequencing approach. total 233,704 sequence reads were obtained classified into 12-267 operational taxonomic units (OTUs). Groundwater sediment divided groups based measured geochemical parameters communities, by hierarchical clustering principal coordinates...
Little is known about the relative importance of spatial and environmental factors to structuring aquatic sedimentary microbial biogeography in lakes. Here, we investigated community composition (MCC) water (n = 35) sediment samples from 16 lakes western China (salinity: freshwater salt saturation; pairwise geographical distance: 9-2027 km) using high-throughput sequencing evaluated (including total, abundant, rare) distributions. Our results showed that were more important than shaping...
Abstract Alpine regions are changing rapidly due to loss of snow and ice in response ongoing climate change. While studies have documented ecological responses alpine lakes streams these changes, our ability predict such outcomes is limited. We propose that the application fundamental rules life can help develop necessary predictive frameworks. focus on four key their interactions: temperature dependence biotic processes from enzymes evolution; wavelength effects solar radiation biological...
Abstract Geothermal environments, such as hot springs and hydrothermal vents, are hotspots for carbon cycling contain many poorly described microbial taxa. Here, we reconstructed 15 archaeal metagenome-assembled genomes (MAGs) from terrestrial spring sediments in China deep-sea vent Guaymas Basin, Gulf of California. Phylogenetic analyses these MAGs indicate that they form a distinct group within the TACK superphylum, thus propose their classification new phylum, ‘Brockarchaeota’, named...
The compositional and physiological responses of autotrophic microbiotas to salinity in lakes remain unclear. In this study, the community composition carbon fixation pathways microorganisms lacustrine sediments with a gradient (82.6 g/L 0.54 g/L) were investigated by using metagenomic analysis. A total 117 metagenome-assembled genomes (MAGs) potentially belonging 20 phyla obtained. abundance these potential autotrophs increased significantly decreasing salinity, variation sediment microbial...
Using RNA-based techniques and hot spring samples collected from Yunnan Province, China, we show that the amoA gene of aerobic ammonia-oxidizing archaea can be transcribed at temperatures higher than 74 degrees C up to 94 C, suggesting archaeal nitrification potentially occur near boiling temperatures.
