Book Synopsis (Endo)symbiotic Methanogenic Archaea by : Johannes H. P. Hackstein
Download or read book (Endo)symbiotic Methanogenic Archaea written by Johannes H. P. Hackstein and published by Springer. This book was released on 2018-11-04 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: This updated monograph deals with methanogenic endosymbionts of anaerobic protists, in particular ciliates and termite flagellates, and with methanogens in the gastrointestinal tracts of vertebrates and arthropods. Further chapters discuss the genomic consequences of living together in symbiotic associations, the role of methanogens in syntrophic degradation, and the function and evolution of hydrogenosomes, hydrogen-producing organelles of certain anaerobic protists. Methanogens are prokaryotic microorganisms that produce methane as an end-product of a complex biochemical pathway. They are strictly anaerobic archaea and occupy a wide variety of anoxic environments. Methanogens also thrive in the cytoplasm of anaerobic unicellular eukaryotes and in the gastrointestinal tracts of animals and humans. The symbiotic methanogens in the gastrointestinal tracts of ruminants and other “methanogenic” mammals contribute significantly to the global methane budget; especially the rumen hosts an impressive diversity of methanogens. This makes this updated volume an interesting read for scientists and students in Microbiology and Physiology.

Book Synopsis Mitochondria and Anaerobic Energy Metabolism in Eukaryotes by : William F. Martin
Download or read book Mitochondria and Anaerobic Energy Metabolism in Eukaryotes written by William F. Martin and published by Walter de Gruyter GmbH & Co KG. This book was released on 2020-12-07 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mitochondria are sometimes called the powerhouses of eukaryotic cells, because mitochondria are the site of ATP synthesis in the cell. ATP is the universal energy currency, it provides the power that runs all other life processes. Humans need oxygen to survive because of ATP synthesis in mitochondria. The sugars from our diet are converted to carbon dioxide in mitochondria in a process that requires oxygen. Just like a fire needs oxygen to burn, our mitochondria need oxygen to make ATP. From textbooks and popular literature one can easily get the impression that all mitochondria require oxygen. But that is not the case. There are many groups of organismsm known that make ATP in mitochondria without the help of oxygen. They have preserved biochemical relicts from the early evolution of eukaryotic cells, which took place during times in Earth history when there was hardly any oxygen avaiable, certainly not enough to breathe. How the anaerobic forms of mitochondria work, in which organisms they occur, and how the eukaryotic anaerobes that possess them fit into the larger picture of rising atmospheric oxygen during Earth history are the topic of this book.
Book Synopsis The Prokaryotes by : Edward F. DeLong
Download or read book The Prokaryotes written by Edward F. DeLong and published by Springer. This book was released on 2014-10-13 with total page 567 pages. Available in PDF, EPUB and Kindle. 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

Book Synopsis The Rumen Microbial Ecosystem by : P.N. Hobson
Download or read book The Rumen Microbial Ecosystem written by P.N. Hobson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 741 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Preface to the first edition of this book explained the reasons for the publication of a comprehensive text on the rumen and rumen microbes in 1988. The microbes of the ruminant's forestomach and those in related organs in other animals and birds provide the means by which herbivorous animals can digest and obtain nutriment from vegetation. In turn, humans have relied, and still do rely, on herbivores for much of their food, clothing and motive power. Herbivores also form the food of carnivorous animals and birds in the wild. The importance of the rumen microorganisms is thus apparent. But, while a knowledge of rumen organisms is not strictly neces sary for the normal, practical feeding of farm animals, in recent years there has been much more emphasis on increasing the productivity of domesti cated animals and in rearing farm animals on unusual feedstuffs. Here, a knowledge of the reactions of the rumen flora, and the limits to these reactions, can be invaluable. In addition, anaerobic rumen-type microor ganisms are found in the intestines of omnivores, including humans, and can be implicated in diseases of humans and animals. They are also found in soils and natural waters, where they playa part in causing pollution and also in reducing it, while the same organisms confined in artificial systems are essential for the purification of sewage and other polluting and toxic wastes.
Book Synopsis Symbiotic Interactions Among Protists, Archaea, and Bacteria in Low Oxygen Environments by : Marissa Brett Hirst
Download or read book Symbiotic Interactions Among Protists, Archaea, and Bacteria in Low Oxygen Environments written by Marissa Brett Hirst and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In the natural world, most bacteria, archaea, and microbial eukaryotes live in close association with other microbes, and are often key symbiotic residents in protists (single-celled microbial eukaryotes excluding fungi) as well as multicellular eukaryotic hosts. Symbiosis, or "the living together of unlike organisms," has been a major driving force in shaping the evolution of the eukaryotic cell. Partnerships between eukaryotes and microorganisms are important because they have a wide taxonomic distribution across the tree of life, suggesting that symbioses play an essential role in the evolution of the species involved. Symbiosis-specific genes, pathways, and structures have also been identified, which are a direct result of evolution favoring the maintenance of the partnership. Lastly, microorganisms make up the greatest biomass and are also responsible for the most complex biochemical reactions on Earth, which makes symbioses between microbes and eukaryotes crucial for driving the evolution of communities. One common misconception regarding microbial eukaryotes is that they are absent from anaerobic environments, but in fact, they are common in a variety of anaerobic habitats including tidal marshes, microbial mats, anoxic marine basins, and the guts of many animals. Although the eukaryotic lineage of the tree of life is primarily composed of single-celled microbial eukaryotes, little is known about free-living protists (with the exception of pathogens). The second chapter of this dissertation focuses on a successful, new method used to describe the diversity of protists in diverse environments by linking culture-independent small subunit ribosomal RNA (SSU rRNA) sequencing to the morphology of protists. Anaerobic environments are habitats that are strongly influenced by microbially-mediated, symbiosis driven biogeochemical cycling. Many microorganisms cannot perform anaerobic respiration, but instead, ferment organic acids and generate ATP in the process. In anaerobic habitats; however, a single fermenting microbe cannot completely catabolize carbon substrates to carbon dioxide without the concerted activity with other microbial anaerobes. In this regard, one microbe lives off of the byproducts of another microorganism and neither microbe could survive on its own. This type of mutualism is known as syntrophy and is a thermodynamically interdependent lifestyle. One environment in which anaerobic microbial eukaryotes are prevalent and have intimate partnerships with bacteria and archaea, is the cow rumen. Rumen ciliates ferment organic acids to acetate or other volatile fatty acids while producing ATP and generating carbon dioxide and dihydrogen. Fermentation by rumen ciliates is an endergonic reaction in the rumen, but becomes exergonic when it is coupled to methanogenesis. Methanogens utilize carbon dioxide as a carbon source and dihydrogen as an energy source; the coupling of fermentation and methanogenesis is known as "interspecies hydrogen transfer" (IHT). IHT is known to occur between free-living methanogens and rumen ciliates, but a syntrophic symbiosis between ciliates and methanogens has not been confirmed in the literature. The third chapter of this dissertation identifies and describes the underlying metabolism of the first two putative, obligate, endosymbiotic methanogenic archaea in ciliates using fluorescence activated cell sorting (FACS), metagenomic sequencing, assembly, and annotation, and rRNA-targeted fluorescent in situ hybridization (FISH). Lastly, symbioses between bacteria in anaerobic environments can drive cycling in anoxic marine environments, and in particular Oxygen Minimum Zones (OMZs). In suboxic waters and OMZs specifically, denitrification (conversion of nitrate to dinitrogen) is limited by the diffusive flux of nitrate from water into the overlying sediments; however, the production of dinitrogen occurs below these limits, suggesting that an alternative, microbiologically driven metabolic process may be responsible for the loss of nitrogen from OMZs. Anammox bacteria are present in OMZs and gain valuable free energy by reducing ammonium to nitrite while producing dinitrogen (NO3− [arrow right] NO2− [arrow right] NH4+). In addition, Thioploca (macroscopic bacteria) are found in OMZs, and are chemolithoautotrophic sulfur-oxiding proteobacteria that glide vertically through marine sediments. Thioploca couples sulfide oxidation with dissimilatory nitrate/nitrite reduction at depth (NO3− + H2S + H2O [arrow right] SO4−2 + NH4+) but also converts large stores of nitrate to nitrite and generates elemental sulfur that it stores in vacuoles within its cells (NO3− + H2S [arrow right] NO2− + S0 + H2O). Based on geochemical and isotopic observations, a symbiosis between anammox bacteria and Thioploca was hypothesized to be the driving force behind the loss of dinitrogen from marine sediments underlying OMZs. The last chapter of this dissertation provides molecular (SSU rRNA sequence data), microscopic data (rRNA-targeted FISH), and isotopic evidence supporting the hypothesis that there is a symbiosis between Thioploca and anammox bacteria, responsible for upwards of 20% nitrogen loss from OMZs.
Book Synopsis The Cosmic Zoo by : Dirk Schulze-Makuch
Download or read book The Cosmic Zoo written by Dirk Schulze-Makuch and published by Springer. This book was released on 2017-11-18 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Are humans a galactic oddity, or will complex life with human abilities develop on planets with environments that remain habitable for long enough? In a clear, jargon-free style, two leading researchers in the burgeoning field of astrobiology critically examine the major evolutionary steps that led us from the distant origins of life to the technologically advanced species we are today. Are the key events that took life from simple cells to astronauts unique occurrences that would be unlikely to occur on other planets? By focusing on what life does - it's functional abilities - rather than specific biochemistry or anatomy, the authors provide plausible answers to this question. Systematically exploring the various pathways that led to the complex biosphere we experience on planet Earth, they show that most of the steps along that path are likely to occur on any world hosting life, with only two exceptions: One is the origin of life itself – if this is a highly improbable event, then we live in a rather “empty universe”. However, if this isn’t the case, we inevitably live in a universe containing a myriad of planets hosting complex as well as microbial life - a “cosmic zoo”. The other unknown is the rise of technologically advanced beings, as exemplified on Earth by humans. Only one technological species has emerged in the roughly 4 billion years life has existed on Earth, and we don’t know of any other technological species elsewhere. If technological intelligence is a rare, almost unique feature of Earth's history, then there can be no visitors to the cosmic zoo other than ourselves. Schulze-Makuch and Bains take the reader through the history of life on Earth, laying out a consistent and straightforward framework for understanding why we should think that advanced, complex life exists on planets other than Earth. They provide a unique perspective on the question that puzzled the human species for centuries: are we alone?

Book Synopsis Chemical Biomarkers in Aquatic Ecosystems by : Thomas S. Bianchi
Download or read book Chemical Biomarkers in Aquatic Ecosystems written by Thomas S. Bianchi and published by Princeton University Press. This book was released on 2011-02-28 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook provides a unique and thorough look at the application of chemical biomarkers to aquatic ecosystems. Defining a chemical biomarker as a compound that can be linked to particular sources of organic matter identified in the sediment record, the book indicates that the application of these biomarkers for an understanding of aquatic ecosystems consists of a biogeochemical approach that has been quite successful but underused. This book offers a wide-ranging guide to the broad diversity of these chemical biomarkers, is the first to be structured around the compounds themselves, and examines them in a connected and comprehensive way. This timely book is appropriate for advanced undergraduate and graduate students seeking training in this area; researchers in biochemistry, organic geochemistry, and biogeochemistry; researchers working on aspects of organic cycling in aquatic ecosystems; and paleoceanographers, petroleum geologists, and ecologists. Provides a guide to the broad diversity of chemical biomarkers in aquatic environments The first textbook to be structured around the compounds themselves Describes the structure, biochemical synthesis, analysis, and reactivity of each class of biomarkers Offers a selection of relevant applications to aquatic systems, including lakes, rivers, estuaries, oceans, and paleoenvironments Demonstrates the utility of using organic molecules as tracers of processes occurring in aquatic ecosystems, both modern and ancient
Book Synopsis Prokaryotic Cell Wall Compounds by : Helmut König
Download or read book Prokaryotic Cell Wall Compounds written by Helmut König and published by Springer Science & Business Media. This book was released on 2010-03-18 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microbial cell wall structures play a significant role in maintaining cells’ shape, as protecting layers against harmful agents, in cell adhesion and in positive and negative biological activities with host cells. All prokaryotes, whether they are bacteria or archaea, rely on their surface polymers for these multiple functions. Their surfaces serve as the indispensable primary interfaces between the cell and its surroundings, often mediating or catalyzing important interactions. Prokaryotic Cell Wall Compounds summarizes the current state of knowledge on the prokaryotic cell wall. Topics concerning bacterial and archaeal polymeric cell wall structures, biological activities, growth and inhibition, cell wall interactions and the applications of cell wall components, especially in the field of nanobiotechnology, are presented.
Book Synopsis Uncultivated Microorganisms by : Slava S. Epstein
Download or read book Uncultivated Microorganisms written by Slava S. Epstein and published by Springer Science & Business Media. This book was released on 2009-09-01 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1898, an Austrian microbiologist Heinrich Winterberg made a curious observation: the number of microbial cells in his samples did not match the number of colonies formed on nutrient media (Winterberg 1898). About a decade later, J. Amann qu- tified this mismatch, which turned out to be surprisingly large, with non-growing cells outnumbering the cultivable ones almost 150 times (Amann 1911). These papers signify some of the earliest steps towards the discovery of an important phenomenon known today as the Great Plate Count Anomaly (Staley and Konopka 1985). Note how early in the history of microbiology these steps were taken. Detecting the Anomaly almost certainly required the Plate. If so, then the period from 1881 to 1887, the years when Robert Koch and Petri introduced their key inventions (Koch 1881; Petri 1887), sets the earliest boundary for the discovery, which is remarkably close to the 1898 observations by H. Winterberg. Celebrating its 111th anniversary, the Great Plate Count Anomaly today is arguably the oldest unresolved microbiological phenomenon. In the years to follow, the Anomaly was repeatedly confirmed by all microb- logists who cared to compare the cell count in the inoculum to the colony count in the Petri dish (cf., Cholodny 1929; Butkevich 1932; Butkevich and Butkevich 1936). By mid-century, the remarkable difference between the two counts became a universally recognized phenomenon, acknowledged by several classics of the time (Waksman and Hotchkiss 1937; ZoBell 1946; Jannasch and Jones 1959).
Book Synopsis Biocommunication of Archaea by : Guenther Witzany
Download or read book Biocommunication of Archaea written by Guenther Witzany and published by Springer. This book was released on 2017-09-27 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Archaea represent a third domain of life with unique properties not found in the other domains. Archaea actively compete for environmental resources. They perceive themselves and can distinguish between ‘self’ and ‘non-self’. They process and evaluate available information and then modify their behaviour accordingly. They assess their surroundings, estimate how much energy they need for particular goals, and then realize the optimum variant. These highly diverse competences show us that this is possible owing to sign(aling)- mediated communication processes within archaeal cells (intra-organismic), between the same, related and different archaeal species (interorganismic), and between archaea and nonarchaeal organisms (transorganismic). This is crucial in coordinating growth and development, shape and dynamics. Such communication must function both on the local level and between widely separated colony parts. This allows archaea to coordinate appropriate response behaviors in a differentiated manner to their current developmental status and physiological influences. This book will orientate further investigations on how archaeal ecosphere inhabitants communicate with each other to coordinate their behavioral patterns and whats the role of viruses in this highly dynamic interactional networks.
