Microbiology of Barrier Component Analogues of a Deep Geological Repository
Microbiology of Barrier Component Analogues of a Deep Geological Repository by Rachel Beaver A thesis presented to the University of Waterloo in fulfillment of the thesis requirement for the degree of Master of Science in Biology Waterloo, Ontario, Canada, 2020 ©Rachel Beaver 2020 Author’s Declaration This thesis consists of material all of which I authored or co-authored: see Statement of Contributions included in the thesis. This is a true copy of the thesis, including any required final revisions, as accepted by my examiners. I understand that my thesis may be made electronically available to the public. ii Statement of Contributions Chapter 2 The Tsukinuno bentonite sampling was coordinated by Erik Kremmer (NWMO). The Opalinus core was received from Niels Burzan and Rizlan Bernier-Latmani (École Polytechnique Fédérale de Lausanne, Switzerland). The Northern Ontario crystalline rock core sampling was coordinated by Jeff Binns (Nuclear Waste Management Organization). Sian Ford (McMaster University) swabbed the outer layer of the Northern Ontario crystalline rocK core and crushed the inner layer. Melody Vachon (University of Waterloo) assisted with the cultivation of anaerobic heterotrophs and SRB. iii Abstract Many countries are in the process of designing and implementing long-term storage solutions for used nuclear fuel. Like many of these countries, Canada is considering a deep geological repository (DGR) wherein used fuel bundles will be placed in copper-coated carbon steel used fuel containers encased in bentonite buffer boxes. Previously published research has simulated aspects of a DGR experimentally to identify DGR conditions that would prevent microbial activity. Although such microcosm-type experiments can observe microbial growth and activity over relatively limited time frames, a DGR will remain functional for at least a million years, and will be exposed to fluctuating environmental conditions. -

Tapping into the Hidden Biotechnological Potential through Metagenomics 5. Unexplored Frontiers and Future Prospects Acknowledgements Glossary Bibliography Biographical Sketches Summary Over the past few decades the extremes at which life thrives has continued to challenge our understanding of biochemistry, biology and evolution. As more new extremophiles are brought into laboratory culture, they have provided a multitude of new potential applications for biotechnology. Furthermore, more recently, innovative culturing approaches, environmental genome sequencing and whole genome sequencing have provided new opportunities for biotechnological exploration of extremophiles. 1. Introduction Organisms that live at the extremes of pH (>pH 8.5,< pH 5.0), temperature (>45°C, <15°C), pressure (>500 atm), salinity (>1.0M NaCl) and in high concentrations of recalcitrant substances or heavy metals (extremophiles) represent one of the last frontiers for biotechnological and industrial discovery.

Our findings indicate that C. proteolyticus does not belong to the phylum Firmicutes and that the Thermotogae phylum Dictyoglomi is not closely related to either the phylum Firmicutes or Synergistetes but to the phylum Thermotogae. © 2011 Elsevier Inc. -

Existing rooting methods are hampered by evolutionary rate heterogeneity or the unavailability of auxiliary phylogenetic information. We present a novel rooting approach, the minimal ancestor deviation (MAD) method, which embraces heterotachy by utilizing all pairwise topological and metric information in unrooted trees. We demonstrate the method in comparison to existing rooting methods by the analysis of phylogenies from eukaryotes and prokaryotes. MAD correctly recovers the kno wn root of eukaryotes and uncovers evidence for cyanobacteria origins in the ocean. MAD is more robust and co nsistent than existing methods, provides measures of the root inference quality, and is applicable to any tree with branch lengths. -

Global Metagenomic Survey Reveals a New Bacterial Candidate Phylum in Geothermal Springs

Ivanova1 Analysis of the increasing wealth of metagenomic data collected from diverse environments can lead to the discovery of novel branches on the tree of life. Here we analyse 5.2 Tb of metagenomic data collected globally to discover a novel bacterial phylum (‘Candidatus Kryptonia’) found exclusively in high-temperature pH-neutral geothermal springs. This lineage had remained hidden as a taxonomic ‘blind spot’ because of mismatches in the primers commonly used for ribosomal gene surveys. Genome reconstruction from metagenomic data combined with single-cell genomics results in several high-quality genomes representing four genera from the new phylum. Metabolic reconstruction indicates a heterotrophic lifestyle with conspicuous nutritional deficiencies, suggesting the need for metabolic complementarity with other microbes. Co-occurrence patterns identifies a number of putative partners, including an uncultured Armatimonadetes lineage. The discovery of Kryptonia within previously studied geothermal springs underscores the importance of globally sampled metagenomic data in detection of microbial novelty, and highlights the extraordinary diversity of microbial life still awaiting discovery. 1 Department of Energy Joint Genome Institute, Walnut Creek, California 94598, USA. 2 Department of Biological Sciences, University of Calgary, Calgary, Alberta T2N 1N4, Canada. -

However, their recalcitrance currently makes lignocellulose use limited. In natural environments, microbial communities can completely deconstruct lignocellulose by synergistic action of a set of enzymes and proteins. Microbial degradation of lignin by fungi, important lignin degraders in nature, has been intensively studied. More recently, bacteria have also been described as able to break down lignin, and to have a central role in recycling this plant polymer. Nevertheless, bacterial deconstruction of lignin has not been fully elucidated yet. Direct analysis of environmental samples using metagenomics, metatranscriptomics, and metaproteomics approaches is a powerful strategy to describe/discover enzymes, metabolic pathways, and microorganisms involved in lignin breakdown. Indeed, the use of these complementary techniques leads to a better understanding of the composition, function, and dynamics of microbial communities involved in lignin deconstruction. We focus on omics approaches and their contribution to the discovery of new enzymes and reactions that impact the development of lignin-based bioprocesses. -
