This bacterium was isolated from a freshwater ditch and is of interest because it can grow with a large variety of or- ganic substrates, in particular several aromatic compounds, short-chain and medium- chain fatty acids, which are degraded completely to carbon dioxide coupled to the reduc- tion of sulfate. It can grow autotrophically with H2 + CO2 and sulfate and slowly acetogenically with H2 + CO2, formate or methoxylated aromatic compounds in the ab- sence of sulfate. It does not require any vitamins for growth. Here, we describe the fea- tures of D. gibsoniae strain GrollT together with the genome sequence and annotation. The chromosome has 4,855,529 bp organized in one circular contig and is the largest genome of all sequenced Desulfotomaculum spp. to date. A total of 4,666 candidate pro- tein-encoding genes and 96 RNA genes were identified. Genes of the acetyl-CoA path- way, possibly involved in heterotrophic growth and in CO2 fixation during autotrophic growth, are present. The genome contains a large set of genes for the anaerobic transfor- mation and degradation of aromatic compounds, which are lacking in the other se- quenced Desulfotomaculum genomes.

  • Heat Resistant Thermophilic Endospores in Cold Estuarine Sediments
    Heat resistant thermophilic endospores in cold estuarine sediments Emma Bell Thesis submitted for the degree of Doctor of Philosophy School of Civil Engineering and Geosciences Faculty of Science, Agriculture and Engineering February 2016 Abstract Microbial biogeography explores the spatial and temporal distribution of microorganisms at multiple scales and is influenced by environmental selection and passive dispersal. Understanding the relative contribution of these factors can be challenging as their effects can be difficult to differentiate. Dormant thermophilic endospores in cold sediments offer a natural model for studies focusing on passive dispersal. Understanding distributions of these endospores is not confounded by the influence of environmental selection; rather their occurrence is due exclusively to passive transport. Sediment heating experiments were designed to investigate the dispersal histories of various thermophilic spore-forming Firmicutes in the River Tyne, a tidal estuary in North East England linking inland tributaries with the North Sea. Microcosm incubations at 50-80°C were monitored for sulfate reduction and enriched bacterial populations were characterised using denaturing gradient gel electrophoresis, functional gene clone libraries and high-throughput sequencing. The distribution of thermophilic endospores among different locations along the estuary was spatially variable, indicating that dispersal vectors originating in both warm terrestrial and marine habitats contribute to microbial diversity in estuarine and marine environments. In addition to their persistence in cold sediments, some endospores displayed a remarkable heat-resistance surviving multiple rounds of autoclaving. These extremely heat-resistant endospores are genetically similar to those detected in deep subsurface environments, including geothermal groundwater investigated from a nearby terrestrial borehole drilled to >1800 m depth with bottom temperatures in excess of 70°C.

  • CO-Dependent Hydrogen Production by the Facultative Anaerobe Parageobacillus Thermoglucosidasius
    Mohr et al. Microb Cell Fact (2018) 17:108 https://doi.org/10.1186/s12934-018-0954-3 Microbial Cell Factories RESEARCH Open Access CO‑dependent hydrogen production by the facultative anaerobe Parageobacillus thermoglucosidasius Teresa Mohr1,4* , Habibu Aliyu1, Raphael Küchlin1, Shamara Polliack2, Michaela Zwick1, Anke Neumann1, Don Cowan2 and Pieter de Maayer3 Abstract Background: The overreliance on dwindling fossil fuel reserves and the negative climatic efects of using such fuels are driving the development of new clean energy sources. One such alternative source is hydrogen (H­ 2), which can be generated from renewable sources. Parageobacillus thermoglucosidasius is a facultative anaerobic thermophilic bacte- rium which is frequently isolated from high temperature environments including hot springs and compost. Results: Comparative genomics performed in the present study showed that P. thermoglucosidasius encodes two evolutionary distinct ­H2-uptake [Ni-Fe]-hydrogenases and one ­H2-evolving hydrogenases. In addition, genes encod- ing an anaerobic CO dehydrogenase (CODH) are co-localized with genes encoding a putative ­H2-evolving hydroge- nase. The co-localized of CODH and uptake hydrogenase form an enzyme complex that might potentially be involved in catalyzing the water-gas shift reaction (CO ­H2O ­CO2 ­H2) in P. thermoglucosidasius. Cultivation of P. thermo- glucosidasius DSM ­2542T with an initial gas atmosphere+ → of 50%+ CO and 50% air showed it to be capable of growth at elevated CO concentrations (50%). Furthermore, GC analyses showed that it was capable of producing hydrogen at an equimolar conversion with a fnal yield of 1.08 ­H2/CO. Conclusions: This study highlights the potential of the facultative anaerobic P.

Pyrrhocoridae, Pyrrhocoris sibiricus, digestion, gut microbiota, community structure, functional profi ling, next- generation sequencing, 16S rRNA gene Abstract. In pyrrhocorids, digestion of food occurs mainly in the midgut, which is divided into four parts (M1–M4), and takes be- tween three and four days. Food is retained in M1 for about 5 h and passes quickly through M4. However, food is retained in M2 and M3 much longer, about 70 to 90 h. The different stages in digestion may be infl uenced by different microbial populations in the different parts of the midgut. In the present study, the microbiota in the four parts of the midgut of Pyrrhocoris sibiricus were analysed in detail using high-throughput sequencing of the 16S rRNA V3–V4 region. The most abundant bacteria in M3 were Actinobacteria (Coriobacteriaceae) whereas it was Proteobacteria (gammaproteobacteria) in M1, M2 and M4. Actinobacteria was the second most abundant bacterial group in M2. According to the PCA analysis, M2 and M3 have the most similar bacterial com- munities.

Common use of dsrAB as a functional marker showed that dsrAB richness in many environments is dominated by novel sequence variants and collectively represents an extensive, largely uncharted sequence assemblage. Here, we established a comprehensive, manually curated dsrAB/DsrAB database and used it to categorize the known dsrAB diversity, reanalyze the evolutionary history of dsrAB and evaluate the coverage of published dsrAB-targeted primers. Based on a DsrAB consensus phylogeny, we introduce an operational classification system for environmental dsrAB sequences that integrates established taxonomic groups with operational taxonomic units (OTUs) at multiple phylogenetic levels, ranging from DsrAB enzyme families that reflect reductive or oxidative DsrAB types of bacterial or archaeal origin, superclusters, uncultured family-level lineages to species-level OTUs.

One such lineage of deep subsurface-dwelling bacteria is an uncultivated member of the Firmicutes phylum that can dominate molecular surveys from both marine and continental rock fracture fluids, sometimes forming the sole member of a single-species microbiome. Here, we reconstructed a genome from basalt- hosted fluids of the deep subseafloor along the eastern Juan de Fuca Ridge flank and used a phylogenomic analysis to show that, despite vast differences in geographic origin and habitat, it forms a monophyletic clade with the terrestrial deep subsurface genome of ``Candidatus Desulforudis audaxviator'' MP104C. While a limited number of differences were observed between the marine genome of ``Candidatus Desulfopertinax cowenii'' modA32 and its terrestrial relative that may be of potential adaptive impor- tance, here it is revealed that the two are remarkably similar thermophiles possessing the genetic capacity for motility, sporulation, hydrogenotrophy, chemoorganotrophy, Submitted 13 November 2016 dissimilatory sulfate reduction, and the ability to fix inorganic carbon via the Wood- Accepted 1 March 2017 Ljungdahl pathway for chemoautotrophic growth.

Previous studies have revealed that corrosions are generated mainly by microbial activities and they are now called as Microbial Influenced Corrosion (MIC) or simply bio-corrosion. Bacterial species actually causing bio-corrosion is crucial for the suppression of the corrosion. To diagnose and give proper treatment to pipelines in industrial plants, it is essential to identify the bacterial species responsible for bio-corrosions. For attaining at this aim, I conducted an analysis of the microbial community at the corrosion sites in pipelines of oil plants, using the comparative metagenomic analysis along with bioinformatics and statistics. In this study, I collected and analyzed various bio-corrosion samples from four different oil fields.
