“…dsrB gene OTUs affiliated with Syntrophobacterales, Group I, Group II and Group III were detected in both QZM and DJ. Syntrophobacterales was comprised of 38% of the total dsrB genes, which were closely related to those retrieved from Three Gorge Reservoir, Evander Mine and Mafic sill ( Figure S1 ) [ 29 ]. The dsrB gene OTUs affiliated with the unclassified Group I, Group II and Group III showed no relationship to any known dsrB gene sequences and thus the unclassified Group I, Group II and Group III may be novel Deltaproteobacteria lineages.…”

“…Sulfate concentration was considered an important environmental factor affecting the rate of sulfate reduction and the abundance of SRB. On the other hand, the sulfate concentration also affected the diversity of the sulfate-reducing community, with a low sulfate concentration, the Firmicutes -like group was the predominant sulfate reducer at 0.8 mbsf in the SMTZ [ 29 ]. Sulfate concentration was important factor shaping the distribution of dsrB gene diversity in the Tibetan hot springs.…”

“…Most known SRPs contain sulfate reductase, which catalyzes the transformation of sulfate to sulfide [ 14 , 15 ]. The large subunit of sulfate reductase is encoded by the conservative dsrAB gene, a widely accepted gene marker for studying SRP distribution and activity in various environments, such as freshwater lake sediment [ 16 ], hot springs [ 17 ], marine sediments [ 18 , 19 , 20 , 21 , 22 ], hypersaline soda lakes [ 23 ], paddy soils [ 24 ], acid mine drainages [ 25 ], deep-sea hydrothermal vents [ 26 ], freshwater wetlands [ 27 ], aquifer environments [ 28 ], estuarine sediments [ 29 ], and deep terrestrial subsurface [ 30 ]. These previous studies showed that SRP were diverse in various environments and their sulfate reduction activity could be correlated with environmental factors such as temperature, pH and water chemistry [ 18 , 22 , 31 ].…”

The distribution and diversity of sulfate/sulfite reduction prokaryotic (SRP) communities in hot springs from the Quzhuomu and Daggyai Geothermal Zone of Tibetan, China, was reported for the first time. In hot springs that are naturally hyperthermal and anoxic, the sulfur cycle is one of the most active cycles of the elements. The distribution of SRP in response to temperature is of great importance to the understanding of biogeochemical cycling of sulfur in geothermal features. Little is known about the SRP in geothermal zone. In this study, the diversity of SRP was investigated in the sediments from the Daggyai and Quzhuomu geothermal zone using PCR amplification, cloning and sequencing of the dissimilatory sulfite reductase beta subunit gene (dsrB). The abundance of dsrB and 16S rRNA genes, were determined by quantitative polymerase chain reactions. In addition, correlations of the SRP assemblages with environmental factors were analyzed by the aggregated boosted tree (ABT) statistical analysis. The results showed that SRP populations were diverse, but were mainly composed of Desulfobacterales, Desulfovibrionales, Syntrophobacterales, Clostridia and Nitrospirales, and large fraction (25%) of novel sequences have branched groups in the dsrB phylogenetic tree. In Quzhuomu geothermal zone, sulfate-rich hot springs are characterized by thick bacterial mats that are green or red and the SRP populations mainly appear at mid-temperature (50 °C to 70 °C). In low-sulfate hot springs in the Daggyai geothermal zone, although gray or pink streamers are widely formed at 60 °C to 80 °C, they prefer to inhabit in green mat at lower temperature (30 °C to 50 °C). With increasing temperature, the diversity of the dsrB gene at the OTU level (cutoff 97%) decreased, while its relative abundance increased. This result suggests that temperature played an important role in affecting dsrB gene distribution.

“…Relationships between the microbial structure and distribution and hydrated methane in deep marine sediments have received worldwide attention. Extensive studies have been conducted to characterize microbial diversity, activity and importance in methane hydrate-bearing subseafloor sediments, such as those in the Cascadia Margin ( Cragg et al, 1995 ; Bidle et al, 1999 ; Lanoil et al, 2001 , 2005 ; Marchesi et al, 2001 ; Mills et al, 2003 , 2005 ; Knittel et al, 2005 ; Inagaki et al, 2006 ; Nunoura et al, 2008 ), Nankai Trough ( Reed et al, 2002 ; Kormas et al, 2003 ; Newberry et al, 2004 ; Mills et al, 2012 ; Katayama et al, 2016 , 2022 ), East Japan Sea ( Yanagawa et al, 2014 ), Andaman Sea ( Briggs et al, 2012 ), Ulleung Basin ( Jeong et al, 2010 ; Lee et al, 2013 ; Ryu et al, 2013 ; Cho et al, 2017 ), Arctic ( Carrier et al, 2020 ) and Shenhu area of the South China Sea ( Liao et al, 2009 ; Lin et al, 2014 ; Jiao et al, 2015 ; Cui et al, 2019 , 2020 ). A few of these studies were performed to compare the microbial communities in marine sediments with or without gas hydrate ( Inagaki et al, 2006 ; Yanagawa et al, 2014 ; Jiao et al, 2015 ; Cui et al, 2020 ).…”

Biogenic and thermogenic gas are two major contributors to gas hydrate formation. Methane hydrates from both origins may have critical impacts on the ecological properties of marine sediments. However, research on microbial diversity in thermogenic hydrate-containing sediments is limited. This study examined the prokaryotic diversity and distributions along a sediment core with a vertical distribution of thermogenic gas hydrates with different occurrences obtained from the Qiongdongnan Basin by Illumina sequencing of 16S rRNA genes as well as molecular and geochemical techniques. Here, we show that gas hydrate occurrence has substantial impacts on both microbial diversity and community composition. Compared to the hydrate-free zone, distinct microbiomes with significantly higher abundance and lower diversity were observed within the gas hydrate-containing layers. Gammaproteobacteria and Actinobacterota dominated the bacterial taxa in all collected samples, while archaeal communities shifted sharply along the vertical profile of sediment layers. A notable stratified distribution of anaerobic methanotrophs shaped by both geophysical and geochemical parameters was also determined. In addition, the hydrate-free zone hosted a large number of rare taxa that might perform a fermentative breakdown of proteins in the deep biosphere and probably respond to the hydrate formation.

In such conditions, usually microbial consortia of anaerobic methanotrophic Archaea and sulfate-reducing bacteria [ 7 ] and/or Chloroflexi and Gammaproteobacteria [ 8 ], Proteobacteria, Elusimicrobia, and Actinobacteria [ 2 ] are identified. Cyanobacteria, Deferribacteres, and Thaumarchaeota are also abundant, although the taxonomic richness within these phyla is smaller [ 2 ] than in the phyla mentioned above.…”

The main goal of the study was to determine changes in the bacterial structure in bottom sediments occurring over the seasons of the year and to estimate microbial metabolic activity. Bottom sediments were collected four times in the year (spring, summer, autumn, and winter) from 10 different measurement points in Cardinal Pond (Ślesin, NW Poland). The Next-Generation Sequencing (MiSeq Illumina) and Community-Level Physiological Profiling techniques were used for identification of the bacterial diversity structure and bacterial metabolic and functional activities over the four seasons. It was evident that Proteobacteria, Acidobacteria, and Bacteroidetes were the dominant phyla, while representatives of Betaproteobacteria, Gammaproteobacteria, and Deltaproteobacteria predominated at the class level in the bottom sediments. An impact of the season on biodiversity and metabolic activity was revealed with the emphasis that the environmental conditions in summer modified the studied parameters most strongly. Carboxylic and acetic acids and carbohydrates were metabolized most frequently, whereas aerobic respiration I with the use of cytochrome C was the main pathway used by the microbiome of the studied bottom sediments.
