Book Synopsis The Geochemical Origin of Microbes by : William F. Martin
Download or read book The Geochemical Origin of Microbes written by William F. Martin and published by CRC Press. This book was released on 2024-06-27 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a textbook covering the transition from energy releasing reactions on the early Earth to energy releasing reactions that fueled growth in the first microbial cells. It is for teachers and college students with an interest in microbiology, geosciences, biochemistry, evolution, or all of the above. The scope of the book is a quantum departure from existing “origin of life” books in that it starts with basic chemistry and links energy-releasing geochemical processes to the reactions of microbial metabolism. The text reaches across disciplines, providing students of the geosciences an origins/biology interface and bringing a geochemistry/origins interface to students of microbiology and evolution. Beginning with physical chemistry and transitioning across metabolic networks into microbiology, the timeline documents chemical events and organizational states in hydrothermal vents – the only environments known that bridge the gap between spontaneous chemical reactions that we can still observe in nature today and the physiology of microbes that live from H2, CO2, ammonia, phosphorus, inorganic salts and water. Life is a chemical reaction. What it is and how it arose are two sides of the same coin. Key Features Provides clear connections between geochemical reactions and microbial metabolism Focuses on chemical mechanisms and transition metals Richly illustrated with color figures explaining reactions and processes Covers the origin of the Earth, the origin of metabolism, the origin of protein synthesis and genetic information as well as the escape into the wild of the first free-living cells: Bacteria and Archaea

Book Synopsis Linking Ecosystem Function to Microbial Diversity by : Anne E. Bernhard
Download or read book Linking Ecosystem Function to Microbial Diversity written by Anne E. Bernhard and published by Frontiers Media SA. This book was released on 2016-10-20 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the link between microbial diversity and ecosystem processes is a fundamental goal of microbial ecologists, yet we still have a rudimentary knowledge of how changes in diversity affect nutrient cycling and energy transfer in ecosystems. Due to the complexity of the problem, many published studies on this topic have been conducted in artificial or manipulated systems. Although researchers have begun to expose some possible mechanisms using these approaches, most have not yet been able to produce conclusive results that relate directly to natural systems. The few studies that have explored the link between diversity and activity in natural systems have typically focused on specific nutrient cycles or processes, such as nitrification, denitrification, and organic carbon degradation pathways, and the microbes that mediate them. What we have learned from these studies is that there are often strong associations between the physical and chemical features of the environment, the composition of the microbial communities, and their activities, but the rules that govern these associations have not been fully elucidated. These earlier studies of microbial diversity and processes in natural systems provide a framework for additional studies to broaden our understanding of the role of microbial diversity in ecosystem function. The problem is complex, but with recent advances in sequencing technology, -omics, and in-situ measurements of ecosystem processes and their applications to microbial communities, making direct connections between ecosystem function and microbial diversity seems more tractable than ever.

Book Synopsis The Microflora of Lakes and Its Geochemical Activity by : S. I. Kuznetsov
Download or read book The Microflora of Lakes and Its Geochemical Activity written by S. I. Kuznetsov and published by University of Texas Press. This book was released on 1975-12-01 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: The geochemical processes that take place in water bodies do not stem entirely from the activity of bacteria, but are also determined by the biological activity of higher plants and animals. The Microflora of Lakes and Its Geochemical Activity, the first English translation of the work of S. I. Kuznetsov, renowned Soviet microbiologist, is a detailed description of these processes. The Microflora of Lakes opens with a complete outline of the ecology and physical and chemical properties of water bodies and a discussion of the entire complex of hydrobionts, since these factors exert tremendous influence on the microbial population. The work then focuses on the principles of the morphology and physiology of the living cell, background knowledge essential to the understanding of the role of microorganisms in the chemical cycle. Having laid the groundwork for the discussion, Kuznetsov follows with chapters on the distribution of bacteria and transformations of organic matter in lakes. He then examines the role of bacteria in the oxygen regime, and the cycles of organic matter, nitrogen, sulfur, iron, manganese and phosphorus. The last chapter describes the role of microorganisms in sediments of calcium carbonate waters. The Microflora of Lakes and Its Geochemical Activity provides a wealth of information on the microbial limnology of fresh-water lakes throughout the world, particularly in the Soviet Union. As a summary of the geochemical activities as related to the geographic, geological, and physical relationships of fresh-water lakes, it is a monumental study. The Microflora of Lakes was translated for the National Science Foundation, Washington, D.C., by the Israel Program for Scientific Translations in Jerusalem.

Book Synopsis Micro-organisms and Earth Systems by : Hilary Lappin-Scott
Download or read book Micro-organisms and Earth Systems written by Hilary Lappin-Scott and published by Cambridge University Press. This book was released on 2005-10-13 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is growing awareness that important environmental transformations are catalysed, mediated and influenced by microorganisms, and geomicrobiology can be defined as the influence of microorganisms on geologic processes. This is probably the most rapidly growing area of microbiology at present, combining environmental and molecular microbiology together with significant areas of mineralogy, geochemistry and hydrology. This volume focuses on the function of microorganisms in the environment and their influence on 'global' processes. It will include state-of-the art approaches to visualisation, culture and identification, community interactions and gene transfer, and diversity studies in relation to key processes. This overview for researchers and graduate students will represent environmental microbiology in its broadest sense and help to promote exciting collaborations between microbiologists and those in complementary physical and chemical disciplines.
Book Synopsis The Microbial Regulation of Global Biogeochemical Cycles by : Johannes Rousk
Download or read book The Microbial Regulation of Global Biogeochemical Cycles written by Johannes Rousk and published by Frontiers E-books. This book was released on 2014-10-17 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global biogeochemical cycles of carbon and nutrients are increasingly affected by human activities. So far, modeling has been central for our understanding of how this will affect ecosystem functioning and the biogeochemical cycling of carbon and nutrients. These models have been forced to adopt a reductive approach built on the flow of carbon and nutrients between pools that are difficult or even impossible to verify with empirical evidence. Furthermore, while some of these models include the response in physiology, ecology and biogeography of primary producers to environmental change, the microbial part of the ecosystem is generally poorly represented or lacking altogether. The principal pool of carbon and nutrients in soil is the organic matter. The turnover of this reservoir is governed by microorganisms that act as catalytic converters of environmental conditions into biogeochemical cycling of carbon and nutrients. The dependency of this conversion activity on individual environmental conditions such as pH, moisture and temperature has been frequently studied. On the contrary, only rarely have the microorganisms involved in carrying out the processes been identified, and one of the biggest challenges for advancing our understanding of biogeochemical processes is to identify the microorganisms carrying out a specific set of metabolic processes and how they partition their carbon and nutrient use. We also need to identify the factors governing these activities and if they result in feedback mechanisms that alter the growth, activity and interaction between primary producers and microorganisms. By determining how different groups of microorganisms respond to individual environmental conditions by allocating carbon and nutrients to production of biomass, CO2 and other products, a mechanistic as well as quantitative understanding of formation and decomposition of organic matter, and the production and consumption of greenhouse gases, can be achieved. In this Research Topic, supported by the Swedish research councils' programme "Biodiversity and Ecosystem Services in a Changing Landscape" (BECC), we intend to promote this alternative framework to address how cycling of carbon and nutrients will be altered in a changing environment from the first-principle mechanisms that drive them – namely the ecology, physiology and biogeography of microorganisms – and on up to emerging global biogeochemical patterns. This novel and unconventional approach has the potential to generate fresh insights that can open up new horizons and stimulate rapid conceptual development in our basic understanding of the regulating factors for global biogeochemical cycles. The vision for the research topic is to facilitate such progress by bringing together leading scientists as proponents of several disciplines. By bridging Microbial Ecology and Biogeochemistry, connecting microbial activities at the micro-scale to carbon fluxes at the ecosystem-scale, and linking above- and belowground ecosystem functioning, we can leap forward from the current understanding of the global biogeochemical cycles.

Book Synopsis Microbial Metal Respiration by : Johannes Gescher
Download or read book Microbial Metal Respiration written by Johannes Gescher and published by Springer Science & Business Media. This book was released on 2014-02-21 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microbes can respire on metals. This seemingly simple finding is one of the major discoveries that were made in the field of microbiology in the last few decades. The importance of this observation is evident. Metals are highly abundant on our planet. Iron is even the most abundant element on Earth and the forth most abundant element in the Earth’s crust. Hence, in some environments iron, but also other metals or metalloids, are the dominant respiratory electron acceptors. Their reduction massively drives the carbon cycle in these environments and establishes redox cycles of the metallic electron acceptors themselves. These redox cycles are not only a driving force for other biotic reactions but are furthermore necessary for initiating a number of geochemically relevant abiotic redox conversions. Although widespread and ecologically influential, electron transfer onto metals like ferric iron or manganese is biochemically challenging. The challenge is to transfer respiratory electrons onto metals that occur in nature at neutral pH in the form of metal oxides or oxihydroxides that are effectively insoluble. Obviously, it is necessary that the microbes specially adapt in order to catalyze the electron transfer onto insoluble electron acceptors. The elucidation of these adaptations is an exciting ongoing process. To sum it up, dissimilatory metal reduction has wide-spread implications in the field of microbiology, biochemistry and geochemistry and its discovery was one of the major reasons to establish a novel scientific field called geomicrobiology. Recently, the discovery of potential applications of dissimilatory metal reducers in bioremediation or current production in a microbial fuel cell further increased the interest in studying microbial metal reduction.
Book Synopsis Microbial Connections Between the Subsurface Sulfur Cycle and Other Elemental Cycles by : Alexandra V. Turchyn
Download or read book Microbial Connections Between the Subsurface Sulfur Cycle and Other Elemental Cycles written by Alexandra V. Turchyn and published by Frontiers Media SA. This book was released on 2018-11-16 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sulfur has many redox states and is a major metabolite in suboxic and anaerobic environments including, but not restricted to, marine and marginal marine sediments, the water column of oxygen minimum zones, salt marshes and oil wells. Microbially mediated redox cycling of sulfur typically comprises dissimilatory sulfate reduction (MSR), sulfide reoxidation, disproportionation and the oxidation and reduction of sulfur redox intermediates. These processes contribute to the degradation of organic matter, link the cycles of sulfur and carbon, control the production and consumption of methane and are critical for the long term budget of O2 in the atmosphere. Microbial and abiotic processes at redox interfaces also connect the sulfur cycle to the redox cycles of nitrogen, iron and other elements, producing distinctive geochemical and molecular signatures. Studies that couple microbiology with stable isotope geochemistry have informed interpretations of microbial sulfur cycling in modern and past environments. Laboratory-based studies and models of MSR have sought to understand the physiological and environmental controls of the magnitude of sulfur isotope fractionation. The fractionations of stable sulfur and oxygen isotopes during MSR are also used to track enzymatic activity during MSR and processes that oxidize sulfide in the presence of environmental oxidants. Outstanding questions in the field concern the importance of oxidative processes within the natural environment, the delivery of oxidants and carbon sources to the zones of sulfate reduction and the ability to detect or reconstruct oxidative processes from the chemical, isotopic, metagenomic, transcriptomic, proteomic and metabolomics profiles in the environment. Recent studies have emphasized the complex connections between sulfur and methane, iron, nitrogen and other elements. These links may involve the redox cycling of species that occur at concentrations difficult to detect by standard geochemical techniques or that are cycled at very rapid rates (cryptic cycles). Of particular interest is the use of isotope geochemistry to quantify links among various electron acceptors, including sulfate, ferric iron, and nitrate, during the anaerobic methane oxidation. For example, recent geochemical measurements have hinted that microbial sulfate reduction coupled to organic matter oxidation is mechanistically different to when sulfate reduction is coupled to methane oxidation. Recent studies have also suggested a possible contribution of a number of previously uncultured microbial groups in sulfur cycling in sulfidic environments, inspiring further studies of these organisms and their partnerships in anaerobic environments. This Research Topic highlights studies of microbial interactions, processes and communities that couple the sulfur cycle to the cycles of other elements in aphotic environments.
