The interactions of microbial communities in these environments are highly complex and still poorly understood. This work aimed to assess publicly available metagenomes from oil reservoirs and implement a robust pipeline of genome-resolved metagenomics to decipher metabolic and taxonomic profiles of petroleum reservoirs worldwide. Analysis of 301.2 Gb of metagenomic information derived from heavily flooded petroleum reservoirs in China and Alaska to non-flooded petroleum reservoirs in Brazil enabled us to reconstruct 148 metagenome-assembled genomes (MAGs) of high and medium quality. At the phylum level, 74% of MAGs belonged to bacteria and 26% to archaea. The profiles of these MAGs were related to the physicochemical parameters and recovery management applied. -

Received 27 February, 2016; Accepted 27 June, 2016 Microbial communities of six samples from Escravos and Meren oil production facility in Nigeria were examined after biocide treatment using cultural and molecular approaches. Sulfate reducing bacteria (SRB) count and activity were the highest in skimmer pit samples (1N1) which was affiliated with Euryarchchaeota (44%) and Proteobacteria (39%). Treatment of Meren injection water (1N2) with biocides significantly reduced SRB population (102 cell/ml). Sample 1N3 (produced water discharge area) and 1N5 (treated produced water) were dominated by 70.79 and 52% Euryarchaeota, respectively. 1N4 (partially treated produced water) was dominated by Euryarchaeota (51.78%) and Proteobacteria (38%), while 1N6 (produced oil) was dominated by Proteobacteria (28%) and Euryarchaeota (62.6%). Metabolic activities in 1N1, 1N4 and 1N5 were dominated by sulfate reduction and methanogenesis; however, that of 1N2 was dominated only by sulfate reduction, while 1N3 and 1N6 were dominated by methanogenesis. Anaerobic incubation of 1N1 samples gave relatively higher corrosion rates (0.065 mm/year) while 1N2, 1N3 and 1N5 gave moderate corrosion rates (0.018 to 0.037 mm/year). -
Quantification of Tinto River Sediment Microbial Communities
Quantification of Tinto River Sediment Microbial Communities: Importance of Sulfate-Reducing Bacteria and Their Role in Attenuating Acid Mine Drainage Downloaded from Irene Sánchez-Andrea,a,b Katrin Knittel,c Rudolf Amann,c Ricardo Amils,b,d and José Luis Sanza Universidad Autónoma de Madrid, Departamento de Biología Molecular, Madrid, Spaina; Centro de Biología Molecular Severo Ochoa, UAM-CSIC, Madrid, Spainb; Max Planck Institute for Marine Microbiology, Bremen, Germanyc; and Centro de Astrobiología (INTA-CSIC), Torrejón de Ardoz, Spaind Tinto River (Huelva, Spain) is a natural acidic rock drainage (ARD) environment produced by the bio-oxidation of metallic sul- fides from the Iberian Pyritic Belt. This study quantified the abundance of diverse microbial populations inhabiting ARD-related sediments from two physicochemically contrasting sampling sites (SN and JL dams). Depth profiles of total cell numbers dif- fered greatly between the two sites yet were consistent in decreasing sharply at greater depths. Although catalyzed reporter depo- sition fluorescence in situ hybridization with domain-specific probes showed that Bacteria (>98%) dominated over Archaea http://aem.asm.org/ (<2%) at both sites, important differences were detected at the class and genus levels, reflecting differences in pH, redox poten- tial, and heavy metal concentrations. At SN, where the pH and redox potential are similar to that of the water column (pH 2.5 and ؉400 mV), the most abundant organisms were identified as iron-reducing bacteria: Acidithiobacillus spp. and Acidiphilium spp., probably related to the higher iron solubility at low pH. At the JL dam, characterized by a banded sediment with higher pH to 6.2), more reducing redox potential (؊210 mV to 50 mV), and a lower solubility of iron, members of sulfate-reducing 4.2) genera Syntrophobacter, Desulfosporosinus, and Desulfurella were dominant. -
1 Characterization of Sulfur Metabolizing Microbes in a Cold Saline Microbial Mat of the Canadian High Arctic Raven Comery Mast
Characterization of sulfur metabolizing microbes in a cold saline microbial mat of the Canadian High Arctic Raven Comery Master of Science Department of Natural Resource Sciences Unit: Microbiology McGill University, Montreal July 2015 A thesis submitted to McGill University in partial fulfillment of the requirements of the degree of Master in Science © Raven Comery 2015 1 Abstract/Résumé The Gypsum Hill (GH) spring system is located on Axel Heiberg Island of the High Arctic, perennially discharging cold hypersaline water rich in sulfur compounds. Microbial mats are found adjacent to channels of the GH springs. This thesis is the first detailed analysis of the Gypsum Hill spring microbial mats and their microbial diversity. Physicochemical analyses of the water saturating the GH spring microbial mat show that in summer it is cold (9°C), hypersaline (5.6%), and contains sulfide (0-10 ppm) and thiosulfate (>50 ppm). Pyrosequencing analyses were carried out on both 16S rRNA transcripts (i.e. cDNA) and genes (i.e. DNA) to investigate the mat’s community composition, diversity, and putatively active members. In order to investigate the sulfate reducing community in detail, the sulfite reductase gene and its transcript were also sequenced. Finally, enrichment cultures for sulfate/sulfur reducing bacteria were set up and monitored for sulfide production at cold temperatures. Overall, sulfur metabolism was found to be an important component of the GH microbial mat system, particularly the active fraction, as 49% of DNA and 77% of cDNA from bacterial 16S rRNA gene libraries were classified as taxa capable of the reduction or oxidation of sulfur compounds. -
4 Metabolic and Taxonomic Diversification in Continental Magmatic Hydrothermal Systems
Maximiliano J. Amenabar, Matthew R. Urschel, and Eric S. Boyd 4 Metabolic and taxonomic diversification in continental magmatic hydrothermal systems 4.1 Introduction Hydrothermal systems integrate geological processes from the deep crust to the Earth’s surface yielding an extensive array of spring types with an extraordinary diversity of geochemical compositions. Such geochemical diversity selects for unique metabolic properties expressed through novel enzymes and functional characteristics that are tailored to the specific conditions of their local environment. This dynamic interaction between geochemical variation and biology has played out over evolu- tionary time to engender tightly coupled and efficient biogeochemical cycles. The timescales by which these evolutionary events took place, however, are typically in- accessible for direct observation. This inaccessibility impedes experimentation aimed at understanding the causative principles of linked biological and geological change unless alternative approaches are used. A successful approach that is commonly used in geological studies involves comparative analysis of spatial variations to test ideas about temporal changes that occur over inaccessible (i.e. geological) timescales. The same approach can be used to examine the links between biology and environment with the aim of reconstructing the sequence of evolutionary events that resulted in the diversity of organisms that inhabit modern day hydrothermal environments and the mechanisms by which this sequence of events occurred. By combining molecu- lar biological and geochemical analyses with robust phylogenetic frameworks using approaches commonly referred to as phylogenetic ecology [1, 2], it is now possible to take advantage of variation within the present – the distribution of biodiversity and metabolic strategies across geochemical gradients – to recognize the extent of diversity and the reasons that it exists. -

In the delta subclass, the four marine myxobacteria（the order Myxococcales）, Enhygromyxa salina, Haliangium ochroceum, Haliangium tepidum and Plesiocystis pacifica contained spermidine. Fe（III）-reducing two Geobacter species and two Pelobacter species belonging to the order Desulfuromonadales con- tained spermidine. Bdellovibrio bacteriovorus was absent in cellular polyamines. Bacteriovorax starrii contained putrescine and spermidine. Bacteriovorax stolpii contained spermidine and homo- spermidine. Spermidine was the major polyamine in the sulfate-reducing delta proteobacteria belonging to the genera Desulfovibrio, Desulfacinum, Desulfobulbus, Desulfococcus and Desulfurella, and some species of them contained cadaverine. Within the epsilon subclass, three Sulfurospirillum species ubiquitously contained spermidine and one of the three contained sper- midine and cadaverine. Thiomicrospora denitrificans contained cadaverine and spermidine as the major polyamine. These data show that cellular polyamine profiles can be used as a chemotaxonomic marker within delta and epsilon subclasses.

R. China, Chengdu 610041, China. Accepted 1 June, 2011 Thermophilic microbial diversity in production water from a high temperature, water-flooded petroleum reservoir of an offshore oilfield in China was characterized by enrichment and polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) analysis. Six different function enrichment cultures were cultivated one year, at 75°C DGGE and sequence analyses of 16S rRNA gene fragments were used to assess the thermophilic microbial diversity. A total of 27 bacterial and 9 archaeal DGGE bands were excised and sequenced. Phylogenetic analysis of these sequences indicated that 21 bacterial and 7 archaeal phylotypes were affiliated with thermophilic microbe. The bacterial sequences were mainly bonged to the genera Fervidobacterium, Thermotoga, Dictyoglomus, Symbiobacterium, Moorella, Thermoanaerobacter, Desulfotomaculum, Thermosyntropha, Coprothermobacter, Caloramator, Thermacetogenium, and the archaeal phylogypes were represented in the genera Geoglobus and Thermococcus, Methanomethylovorans, Methanothermobacter Methanoculleus and Methanosaeta. So many thermophiles were detected suggesting that they might be common habitants in high-temperature petroleum reservoirs. The results of this work provide further insight into the thermophilic composition of microbial communities in high temperature petroleum reservoirs. -
A Metagenomics Roadmap to the Uncultured Genome Diversity in Hypersaline Soda Lake Sediments Charlotte D
Vavourakis et al. Microbiome (2018) 6:168 https://doi.org/10.1186/s40168-018-0548-7 RESEARCH Open Access A metagenomics roadmap to the uncultured genome diversity in hypersaline soda lake sediments Charlotte D. Vavourakis1 , Adrian-Stefan Andrei2†, Maliheh Mehrshad2†, Rohit Ghai2, Dimitry Y. Sorokin3,4 and Gerard Muyzer1* Abstract Background: Hypersaline soda lakes are characterized by extreme high soluble carbonate alkalinity. Despite the high pH and salt content, highly diverse microbial communities are known to be present in soda lake brines but the microbiome of soda lake sediments received much less attention of microbiologists. Here, we performed metagenomic sequencing on soda lake sediments to give the first extensive overview of the taxonomic diversity found in these complex, extreme environments and to gain novel physiological insights into the most abundant, uncultured prokaryote lineages. Results: We sequenced five metagenomes obtained from four surface sediments of Siberian soda lakes with a pH 10 and a salt content between 70 and 400 g L−1. The recovered 16S rRNA gene sequences were mostly from Bacteria,evenin the salt-saturated lakes. Most OTUs were assigned to uncultured families. We reconstructed 871 metagenome-assembled genomes (MAGs) spanning more than 45 phyla and discovered the first extremophilic members of the Candidate Phyla Radiation (CPR). Five new species of CPR were among the most dominant community members. Novel dominant lineages were found within previously well-characterized functional groups involved in carbon, sulfur, and nitrogen cycling. Moreover, key enzymes of the Wood-Ljungdahl pathway were encoded within at least four bacterial phyla never previously associated with this ancient anaerobic pathway for carbon fixation and dissimilation, including the Actinobacteria. -
