Book excerpt: To address the major role microorganisms play in the biogeochemical cycling of carbon and nutrients in the marine environment, the work presented in this dissertation uses a combination of geochemical and molecular biological techniques to investigate carbon and nitrogen metabolism in the planktonic microbial community of the deep ocean. A method was developed to isolate microbial DNA from the marine water column suitable for radiocarbon analysis, which was then applied to determine the sources of carbon fueling microbial production in the mesopelagic. Fresh organic matter delivered from sinking particles was confirmed as an important carbon source for free-living microbes, but the extent of autotrophic carbon fixation was also significant and variable with depth, highlighting the requirement for particle-delivered reduced nitrogen by the total microbial community in the deep ocean. Both findings stressed the importance of constraining particle-derived carbon and nitrogen flux to the deep ocean. The importance of methane as a carbon source in unique environments above cold methane seeps was examined using both stable carbon isotope measurements of microbial DNA and quantitative PCR of the gene encoding for particulate methane monooxygenase. The carbon isotope measurements showed that methane-carbon played an insignificant role in fueling planktonic microbial production in the deep water column just above methane seeps. The PCR measurements substantiated this result by showing that the methane oxidizing community represented only a small percentage of the microbial community in this environment. And finally, bacterial heterotrophic nitrate assimilation was studied and determined to increase with depth and/or nitrate concentration, but appeared to only be a possible nitrogen acquisition method for a small (> 1%) fraction of the bacterial community. Sequencing of the heterotrophic nitrate assimilation gene isolated from the marine environment further demonstrated that these genes were depth stratified. In addition both isotopic analyses and molecular biological techniques such as quantitative PCR indicated distinct differences between free-living and particle-attached microbial communities. Overall, future research efforts should be focused on expanding the current data set, constraining particle flux, and gaining a better understanding of microbial physiology, including in situ growth rates, in the subsurface marine environment.

Book excerpt: During the past ten years, evidence has developed to indicate that seawater convects through oceanic crust driven by heat derived from creation of lithosphere at the Earth-encircling oceanic ridge-rift system of seafloor spreading centers. This has stimulated multiple lines of research with profound implications for the earth and life sciences. The lines of research comprise the role of hydrothermal convection at seafloor spreading centers in the Earth's thermal regime by cooling of newly formed litho sphere (oceanic crust and upper mantle); in global geochemical cycles and mass balances of certain elements by chemical exchange between circulating seawater and basaltic rocks of oceanic crust; in the concentration of metallic mineral deposits by ore-forming processes; and in adaptation of biological communities based on a previously unrecognized form of chemosynthesis. The first work shop devoted to interdisciplinary consideration of this field was organized by a committee consisting of the co-editors of this volume under the auspices of a NATO Advanced Research Institute (ARI) held 5-8 April 1982 at the Department of Earth Sciences of Cambridge University in England. This volume is a product of that workshop. The papers were written by members of a pioneering research community of marine geologists, geophysicists, geochemists and biologists whose work is at the stage of initial description and interpretation of hydrothermal and associated phenomena at seafloor spreading centers.

Book excerpt: Many organisms in deep-sea environments are extremophiles thriving in extreme conditions: high pressure, high or low temperature, or high concentrations of inorganic compounds. This book presents the microbiology of extremophiles living in the deep sea and describes the isolation, cultivation, and taxonomic identification of microorganisms retrieved from the Mariana Trench, the world's deepest point. Also explained are techniques for recovering pressure-loving bacteria, the barophiles (piezophiles), and for whole genome analysis of Bacillus halodurans C-125. Physiological analysis of the pressure effect in Saccharomyces cerevisiae and Escherichia coli is used to answer the question of how deep-sea organisms survive under high hydrostatic pressure. These research results are useful in both basic science and industrial applications. Readers discover a new microbial world in the ocean depths, with state-of-the-science information on extremophiles.

Available in PDF, EPUB and Kindle. Book excerpt: The world's oceans are essential for sustaining life on Earth and harbour a vast diversity of organisms. Marine microbes play crucial roles in global biogeochemical cycling and are at the base of marine food webs. Due to the technical difficulties associated with sampling northern marine systems, relatively little is known about the microbial community composition and metabolism of these ecosystems. In this thesis work, the community composition and metabolism of northern marine ecosystems, including the Saint Lawrence Estuary, North Water and Canada Basin were described using meta-omic techniques. In the Saint Lawrence Estuary, differences in microbial community structure, metabolic lifestyles and carbon and nitrogen processing pathways were observed between the surface and deep waters. In the North Water, two distinct microbial communities with different taxonomic compositions and differing nutrient acquisition and resource allocation strategies were identified on either side of the polar mixed layer, and a third distinct community was described in the bottom waters. Functional and taxonomic analyses of the North Water polar mixed layer communities suggest a microbial community more typically associated with waters that undergo pulses of primary production on the Canadian side, while the community on the Greenland side was more typical of waters associated with a more steady level of primary production. In the Canada Basin, metagenomics was used to construct 360 Arctic Ocean metagenome assembled genomes. The analysis of six Chloroflexi MAGs revealed their potential for terrestrial derived aromatic compound degradation and that this metabolic capacity was acquired, at least in part, by lateral gene transfer from terrestrial organisms. To facilitate the meta-omic analyses performed in this thesis, a novel method to isolate microbial community DNA and proteins from the same environmental sample preserved in RNAlater was also developed. This thesis not only describes the microbial community composition and metabolism of northern marine systems over a broad geographic range, but also adds to the growing metagenomic and metaproteomic resource-base that can be used to develop and test hypotheses about northern marine microbial systems. Additionally, this work has implications for our understanding of how climate change may affect northern marine ecosystems.

This book was released on 2014 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation presents the analyses of twenty-eight single amplified genomes (SAGs) distributed among four major phyla or candidate phyla of archaea and bacteria : Thaumarchaeota, Proteobacteria, Parcubacteria and Marinimicrobia. Samples were obtained from 8,219 m and 10,908 m depth within the hadal ecosystems of the Puerto Rico Trench (PRT) and Challenger Deep (CHDE) portion of the Mariana Trench, respectively, and microbes associated with seawater, invertebrates and surficial sediments were sorted, amplified by multiple displacement amplification and sequenced using the HiSeq 2000 Illumina platform. Assembled and annotated genomes were analyzed and compared to genomes derived from closely related microbes from other habitats with the goal of understanding PRT and CHDE microbes' metabolic adaptations to deep-sea conditions. Four single amplified genomes (SAGs) were recovered from the PRT: PRT Nitrosopumilus, PRT SAR11, PRT Marinosulfonomonas, and PRT Psychromonas. These microbes are all members of deep-sea phylogenetic clades. The PRT Nitrosopumilus, possesses genes associated with mixotrophy, including those associated with lipoylation and the glycine cleavage pathway, and remarkably, may possess the ability to produce fatty acids and lipids. PRT SAR11 encodes for glycolytic enzymes previously reported to be missing in this highly abundant and cosmopolitan group. The PRT Marinosulfonomonas and PRT Psychromonas SAGs possess genes that may supplement their energy demands through nitrous oxide and hydrogen oxidation. From the CHDE, 13 SAGs were analyzed that belong to the candidate phylum Parcubacteria (OD1), a group of uncultivated microbes characterized by reduced genomes with limited metabolic potential. Comparative genomics was used to examine the metabolic potential harbored by Parcubacteria SAGs (OD1-DSC). Horizontally transferred genes were abundant in the Parcubacteria genomes especially for genes laterally transferred from members of the archaea. Results indicated that some OD1 cells are capable of much greater metabolic versatility and genetic exchange than previously ascribed to this candidate phylum. The other candidate phylum analyzed as part of this dissertation is the Marinimicrobia (Marine Group A, SAR406), which has been suggested to be an abundant contributor in deep ocean microbial communities, but information about their metabolism andphysiology remains minimal. Six Marinimicrobia SAGs were recovered and their phylogenetic and metabolic characteristics were explored. Results revealed two distinct Marinimicrobia clades not associated with previously described Marinimicrobia phylogenetic groups, but mostly associated with sequences obtain from deep-sea environments, particularly sediments. Bioinformatic analyses indicated that Marinimicrobia SAGs take advantage of carbon monoxide and reduced sulfur compounds to supplement their energy requirements. Osmotic and oxidative stress regulation were also found to be over abundant in the hadal Marinimicrobia. Taking all of these genome studies into consideration it is hypothesized that diversified carbon and energy acquisition pathways are a hallmark of many hadal microbes, along with enhanced osmotic pressure adaptation, perhaps as a means to counteract extreme hydrostatic pressure. In all cases this research has expanded the currently available knowledge of the phylogenetic placement and metabolic potential of the microbial groups studied.

Available in PDF, EPUB and Kindle. Book excerpt: Deep subsurface microbiology is a highly active and rapidly advancing research field at the interface of microbiology and the geosciences; it focuses on the detection, identification, quantification, cultivation and activity measurements of bacteria, archaea and eukaryotes that permeate the subsurface biosphere of deep marine sediments and the basaltic ocean and continental crust. The deep subsurface biosphere abounds with uncultured, only recently discovered and – at best - incompletely understood microbial populations. In spatial extent and volume, Earth's subsurface biosphere is only rivaled by the deep sea water column. So far, no deep subsurface sediment has been found that is entirely devoid of microbial life; microbial cells and DNA remain detectable at sediment depths of more than 1 km; microbial life permeates deeply buried hydrocarbon reservoirs, and is also found several kilometers down in continental crust aquifers. Severe energy limitation, either as electron acceptor or donor shortage, and scarcity of microbially degradable organic carbon sources are among the evolutionary pressures that have shaped the genomic and physiological repertoire of the deep subsurface biosphere. Its biogeochemical role as long-term organic carbon repository, inorganic electron and energy source, and subduction recycling engine continues to be explored by current research at the interface of microbiology, geochemistry and biosphere/geosphere evolution. This Research Topic addresses some of the central research questions about deep subsurface microbiology and biogeochemistry: phylogenetic and physiological microbial diversity in the deep subsurface; microbial activity and survival strategies in severely energy-limited subsurface habitats; microbial activity as reflected in process rates and gene expression patterns; biogeographic isolation and connectivity in deep subsurface microbial communities; the ecological standing of subsurface biospheres in comparison to the surface biosphere – an independently flourishing biosphere, or mere survivors that tolerate burial (along with organic carbon compounds), or a combination of both? Advancing these questions on Earth’s deep subsurface biosphere redefines the habitat range, environmental tolerance, activity and diversity of microbial life.

Book excerpt: The Prokaryotes is a comprehensive, multi-authored, peer reviewed reference work on Bacteria and Achaea. This fourth edition of The Prokaryotes is organized to cover all taxonomic diversity, using the family level to delineate chapters. Different from other resources, this new Springer product includes not only taxonomy, but also prokaryotic biology and technology of taxa in a broad context. Technological aspects highlight the usefulness of prokaryotes in processes and products, including biocontrol agents and as genetics tools. The content of the expanded fourth edition is divided into two parts: Part 1 contains review chapters dealing with the most important general concepts in molecular, applied and general prokaryote biology; Part 2 describes the known properties of specific taxonomic groups. Two completely new sections have been added to Part 1: bacterial communities and human bacteriology. The bacterial communities section reflects the growing realization that studies on pure cultures of bacteria have led to an incomplete picture of the microbial world for two fundamental reasons: the vast majority of bacteria in soil, water and associated with biological tissues are currently not culturable, and that an understanding of microbial ecology requires knowledge on how different bacterial species interact with each other in their natural environment. The new section on human microbiology deals with bacteria associated with healthy humans and bacterial pathogenesis. Each of the major human diseases caused by bacteria is reviewed, from identifying the pathogens by classical clinical and non-culturing techniques to the biochemical mechanisms of the disease process. The 4th edition of The Prokaryotes is the most complete resource on the biology of prokaryotes. The following volumes are published consecutively within the 4th Edition: Prokaryotic Biology and Symbiotic Associations Prokaryotic Communities and Ecophysiology Prokaryotic Physiology and Biochemistry Applied Bacteriology and Biotechnology Human Microbiology Actinobacteria Firmicutes Alphaproteobacteria and Betaproteobacteria Gammaproteobacteria Deltaproteobacteria and Epsilonproteobacteria Other Major Lineages of Bacteria and the Archaea

Available in PDF, EPUB and Kindle. Book excerpt: I have enjoyed writing this book. Some of my ideas are controversial. Some of them I know to be true though I have not sufficient evidence for a conviction. My intention is that you should realise that microbes will be as important in the future of the earth as they have been in the past. They have led to our existence, and may help to prevent our destruction; they may even save us from ourselves. i As a student, I was taught that a scientist must be objective, and that every statement or observation must be documented. Also, that a scien tist must seek the truth, and not be satisfied with less. It took me a long time to realize that no human being can be completely objective, and that the truth, even scientific truth, is a chimera. The most that we can get with our human minds and feeble experimentation is an approxima tion, and all we can hope to contribute is a better approximation than we have had to date. Newton's theories were regarded as absolute until Einstein came along; and now it seems that Einstein may be inadequate.

Available in PDF, EPUB and Kindle. Book excerpt: Metabolic Ecology Most of ecology is about metabolism, the ways that organisms use energy and materials. The energy requirements of individuals (their metabolic rates) vary predictably with their body size and temperature. Ecological interactions are exchanges of energy and materials between organisms and their environments. Therefore, metabolic rate affects ecological processes at all levels: individuals, populations, communities and ecosystems. Each chapter focuses on a different process, level of organization, or kind of organism. It lays a conceptual foundation and presents empirical examples. Together, the chapters provide an integrated framework that holds the promise for a unified theory of ecology. The book is intended to be accessible to upper-level undergraduates and graduate students, but also of interest to senior scientists. Its easy-to-read chapters and clear illustrations can be used in lecture and seminar courses. This is an authoritative treatment that will inspire future generations to study metabolic ecology.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents the biodiversity of the Brazilian deep-sea and its many unique geological and biological features, as well as a review of its ecology, conservation, and future research needs. The deep-sea Brazilian margin has an incredible geological heterogeneity with numerous characteristic seafloor features, and latitudinal changes in marine productivity, oceanographic conditions and biological communities have resulted in very distinct biological assemblages at regional and bathymetric scales. It is a tremendously rich ecosystem in terms of living species, from which many well-known historical tales have originated, and with unique importance for the global climate and humanity. Nevertheless, vast areas of the Brazilian margin have been explored for fishing, oil and gas, and other commodities, likely impacting a variety of deep-sea habitats at scales and intensities yet undetermined. This book is intended for students, scholars, professionals and a wide audience interested in the deep-sea in general and, more specifically, in the South Atlantic deep-sea.
