  • Microbial Fe(III) Oxide Reduction Potential in Chocolate Pots Hot Spring, Yellowstone National Park N
    Geobiology (2016), 14, 255–275 DOI: 10.1111/gbi.12173 Microbial Fe(III) oxide reduction potential in Chocolate Pots hot spring, Yellowstone National Park N. W. FORTNEY,1 S. HE,1 B. J. CONVERSE,1 B. L. BEARD,1 C. M. JOHNSON,1 E. S. BOYD2 ANDE.E.RODEN1 1Department of Geoscience, NASA Astrobiology Institute, University of Wisconsin-Madison, Madison, WI, USA 2Department of Microbiology and Immunology, NASA Astrobiology Institute, Montana State University, Bozeman, MT, USA ABSTRACT Chocolate Pots hot springs (CP) is a unique, circumneutral pH, iron-rich, geothermal feature in Yellowstone National Park. Prior research at CP has focused on photosynthetically driven Fe(II) oxidation as a model for mineralization of microbial mats and deposition of Archean banded iron formations. However, geochemical and stable Fe isotopic data have suggested that dissimilatory microbial iron reduction (DIR) may be active within CP deposits. In this study, the potential for microbial reduction of native CP Fe(III) oxides was inves- tigated, using a combination of cultivation dependent and independent approaches, to assess the potential involvement of DIR in Fe redox cycling and associated stable Fe isotope fractionation in the CP hot springs. Endogenous microbial communities were able to reduce native CP Fe(III) oxides, as documented by most probable number enumerations and enrichment culture studies. Enrichment cultures demonstrated sus- tained DIR driven by oxidation of acetate, lactate, and H2. Inhibitor studies and molecular analyses indicate that sulfate reduction did not contribute to observed rates of DIR in the enrichment cultures through abi- otic reaction pathways. Enrichment cultures produced isotopically light Fe(II) during DIR relative to the bulk solid-phase Fe(III) oxides.

  • Constraint-Based Modeling Analysis of the Metabolism of Two Pelobacter Species Jun Sun1*, Shelley a Haveman2,3, Olivia Bui1, Tom R Fahland1,4, Derek R Lovley2
    Sun et al. BMC Systems Biology 2010, 4:174 http://www.biomedcentral.com/1752-0509/4/174 RESEARCH ARTICLE Open Access Constraint-based modeling analysis of the metabolism of two Pelobacter species Jun Sun1*, Shelley A Haveman2,3, Olivia Bui1, Tom R Fahland1,4, Derek R Lovley2 Abstract Background: Pelobacter species are commonly found in a number of subsurface environments, and are unique members of the Geobacteraceae family. They are phylogenetically intertwined with both Geobacter and Desulfuromonas species. Pelobacter species likely play important roles in the fermentative degradation of unusual organic matters and syntrophic metabolism in the natural environments, and are of interest for applications in bioremediation and microbial fuel cells. Results: In order to better understand the physiology of Pelobacter species, genome-scale metabolic models for Pelobacter carbinolicus and Pelobacter propionicus were developed. Model development was greatly aided by the availability of models of the closely related Geobacter sulfurreducens and G. metallireducens. The reconstructed P. carbinolicus model contains 741 genes and 708 reactions, whereas the reconstructed P. propionicus model contains 661 genes and 650 reactions. A total of 470 reactions are shared among the two Pelobacter models and the two Geobacter models. The different reactions between the Pelobacter and Geobacter models reflect some unique metabolic capabilities such as fermentative growth for both Pelobacter species. The reconstructed Pelobacter models were validated by simulating published growth conditions including fermentations, hydrogen production in syntrophic co-culture conditions, hydrogen utilization, and Fe(III) reduction. Simulation results matched well with experimental data and indicated the accuracy of the models. Conclusions: We have developed genome-scale metabolic models of P.

The system achieved high COD removal (91 ± 4.3%) and methane recovery (82 ± 20%) at an organic loading rate of 8.5 kg-COD/(m3·day). The UASB allowed an organic loading rate of 14 kg-COD/(m3·day) with a constant hydraulic retention time of 24 h. The COD of DHS effluent was 370 ± 250 mg-COD/L during the entire experimental period. Thus, the proposed system could be applicable for treating industrial wastewater containing ethylene glycol. Massively parallel 16S rRNA gene sequencing elucidated the microbial community structure of the UASB. The dominant family Pelobacteriaceae could mainly degrade the organic compounds of ethylene glycol and decomposed products of ethanol.

  • (Pelobacter) and Methanococcoides Are Responsible for Choline-Dependent Methanogenesis in a Coastal Saltmarsh Sediment
    The ISME Journal https://doi.org/10.1038/s41396-018-0269-8 ARTICLE Deltaproteobacteria (Pelobacter) and Methanococcoides are responsible for choline-dependent methanogenesis in a coastal saltmarsh sediment 1 1 1 2 3 1 Eleanor Jameson ● Jason Stephenson ● Helen Jones ● Andrew Millard ● Anne-Kristin Kaster ● Kevin J. Purdy ● 4 5 1 Ruth Airs ● J. Colin Murrell ● Yin Chen Received: 22 January 2018 / Revised: 11 June 2018 / Accepted: 26 July 2018 © The Author(s) 2018. This article is published with open access Abstract Coastal saltmarsh sediments represent an important source of natural methane emissions, much of which originates from quaternary and methylated amines, such as choline and trimethylamine. In this study, we combine DNA stable isotope 13 probing with high throughput sequencing of 16S rRNA genes and C2-choline enriched metagenomes, followed by metagenome data assembly, to identify the key microbes responsible for methanogenesis from choline. Microcosm 13 incubation with C2-choline leads to the formation of trimethylamine and subsequent methane production, suggesting that 1234567890();,: 1234567890();,: choline-dependent methanogenesis is a two-step process involving trimethylamine as the key intermediate. Amplicon sequencing analysis identifies Deltaproteobacteria of the genera Pelobacter as the major choline utilizers. Methanogenic Archaea of the genera Methanococcoides become enriched in choline-amended microcosms, indicating their role in methane formation from trimethylamine. The binning of metagenomic DNA results in the identification of bins classified as Pelobacter and Methanococcoides. Analyses of these bins reveal that Pelobacter have the genetic potential to degrade choline to trimethylamine using the choline-trimethylamine lyase pathway, whereas Methanococcoides are capable of methanogenesis using the pyrrolysine-containing trimethylamine methyltransferase pathway.

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.

  • Disentangling Syntrophic Electron Transfer Mechanisms in Methanogenesis Through Electrochemical Stimulation, Omics, and Machine Learning

Read Full License Page 1/25 Abstract Background: Interspecies hydrogen transfer (IHT) and direct interspecies electron transfer (DIET) are two syntrophy models for methanogenesis. Their relative importance in methanogenic environments is still unclear. Our recent discovery of a novel species Candidatus Geobacter eutrophica with the genetic potential of IHT and DIET may serve as a model species to address this knowledge gap. Results: To experimentally demonstrate its DIET ability, we performed electrochemical enrichment of Ca. G. eutrophica-dominating communities under 0 and 0.4 V vs. Ag/AgCl based on the presumption that DIET and extracellular electron transfer (EET) share similar metabolic pathways. After three batches of enrichment, acetate accumulated in all reactors, while propionate was detected only in the electrochemical reactors. Four dominant fermentative bacteria were identied in the core population, and metatranscriptomics analysis suggested that they were responsible for the degradation of fructose and ethanol to propionate, propanol, acetate, and H2.

  • The Genome of Pelobacter Carbinolicus Reveals
    Aklujkar et al. BMC Genomics 2012, 13:690 http://www.biomedcentral.com/1471-2164/13/690 RESEARCH ARTICLE Open Access The genome of Pelobacter carbinolicus reveals surprising metabolic capabilities and physiological features Muktak Aklujkar1*, Shelley A Haveman1, Raymond DiDonato Jr1, Olga Chertkov2, Cliff S Han2, Miriam L Land3, Peter Brown1 and Derek R Lovley1 Abstract Background: The bacterium Pelobacter carbinolicus is able to grow by fermentation, syntrophic hydrogen/formate transfer, or electron transfer to sulfur from short-chain alcohols, hydrogen or formate; it does not oxidize acetate and is not known to ferment any sugars or grow autotrophically. The genome of P. carbinolicus was sequenced in order to understand its metabolic capabilities and physiological features in comparison with its relatives, acetate-oxidizing Geobacter species. Results: Pathways were predicted for catabolism of known substrates: 2,3-butanediol, acetoin, glycerol, 1,2-ethanediol, ethanolamine, choline and ethanol. Multiple isozymes of 2,3-butanediol dehydrogenase, ATP synthase and [FeFe]-hydrogenase were differentiated and assigned roles according to their structural properties and genomic contexts. The absence of asparagine synthetase and the presence of a mutant tRNA for asparagine encoded among RNA-active enzymes suggest that P. carbinolicus may make asparaginyl-tRNA in a novel way. Catabolic glutamate dehydrogenases were discovered, implying that the tricarboxylic acid (TCA) cycle can function catabolically. A phosphotransferase system for uptake of sugars was discovered, along with enzymes that function in 2,3-butanediol production. Pyruvate:ferredoxin/flavodoxin oxidoreductase was identified as a potential bottleneck in both the supply of oxaloacetate for oxidation of acetate by the TCA cycle and the connection of glycolysis to production of ethanol.
