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.

Download or read book Freshwater Microbiology written by Sincere Humphrey and published by Scientific e-Resources. This book was released on 2019-02-19 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the diversity, interactions and activities of microbes within freshwater environments. These form an important part of the biosphere, which also includes oceans, terrestrial environments and the earth's atmosphere. Freshwater environments are considered to include all those sites where freshwater occurs as the main external medium, either in the liquid or frozen state. Water microorganisms are capable of flourishing in all water habitants, from several kilometers below the seafloor to the first millimeter of a shallow trench created by rainwater and into acidic lakes. Three major domains compose water microorganisms-Eukaryota, Archaea and Bacteria - as well as viruses. Their omnipresence impacts the entire biosphere as they are the main producers of energy and carbon flow to other organisms. Some of the microbes decompose organic matter and thus they recycle nutrients in complex manner involved in various geochemical cycles as the nitrogen, the phosphorus and the carbon cycle. Water microbiology is concerned with the microorganisms that live in water, or can be transported from one habitat to another by water. Water can support the growth of many types of microorganisms. This can be advantageous. For example, the chemical activities of certain strains of yeasts provide us with beer and bread. As well, the growth of some bacteria in contaminated water can help digest the poisons from the water. This book will be useful to researchers, teachers and students of microbiology, botany, zoology and agriculture.

This book was released on 2015 with total page 816 pages. Available in PDF, EPUB and Kindle. Book excerpt: All major geochemical cycles on the Earth's surface are mediated by microorganisms. Our understanding of how these microbes have interacted with their environments (and vice versa) throughout Earth's history, and how they will respond to changes in the future, is primarily based on studying their activity in different environments today. The overarching questions that motivate the research presented in the two parts of this thesis -- how do microorganisms shape their environment (and vice versa)? and how can we best study microbial activity in situ? -- have arisen from the ultimate goal of being able to predict microbial activity in response to changes within their environments both past and future. Part one focuses on work related to microbial processes in iron-rich Lake Matano and, more broadly, microbial interactions with the biogeochemical cycling of iron. Primarily, we find that the chelation of ferrous iron by organic ligands can affect the role of iron in anoxic environmental systems, enabling photomixotrophic growth of anoxygenic microorganisms with ferrous iron, as well as catalyzing the oxidation of ferrous iron by denitrification intermediates. These results imply that the ability to grow photomixotrophically on ferrous iron might be more widespread than previously assumed, and that the co-occurrence of chemical and biological processes involved in the coupled biogeochemical cycling of iron and nitrogen likely dominate organic-rich environmental systems. Part two switches focus to in situ measurements of growth activity and comprises work related to microbial processes in the Cystic Fibrosis lung, and more broadly, the physiology of slow growth. We introduce stable isotope labeling of microbial membrane fatty acids and whole cells with heavy water as a new technique to measure microbial activity in a wide range of environments, demonstrate its application in continuous culture in the laboratory at the population and single cell level, and apply the tool to measure the in situ activity of the opportunistic pathogen Staphylococcus aureus within the environment of expectorated mucus from cystic fibrosis patients. We find that the average in situ growth rates of S. aureus fall into a range of generation times between ~12 hours and ~4 days, with substantial heterogeneity at the single-cell level. These data illustrate the use of heavy water as a universal environmental tracer for microbial activity, and highlight the crucial importance of studying the physiology of slow growth in representative laboratory systems in order to understand the role of these microorganisms in their native environments.

Book excerpt: This volume contains a selection of papers presented to the Fourth Internation~l Symposium on Environmental Biogeochemistry (ISEB), and a conference on Biogeochemistry in Relation to Mining Industry and Environmental Pollution (Leaching Conference), held in Canberra, Aust ralia on August 26-31 and September 3-4, 1979, respectively. The ISEB were established to provide "a forum for uninhibited exchange of information and ideas among the biological, chemical, atmospheric and geolorical scientists working in the common area of biogeochemistry, encompassing soil and other earth sciences as well as the hydrosphere and atmosphere", By linking the fourth ISEB with the Leachin~ Conference the scope of discussions was extended to encompass the application of biogeochemical processes to the mining industry. This wide-ranging philosophy is reflected in the breadth and diversity of the subjects covered in this book. The published papers are expanded versions of those presented at the meetings. They have all been scrutinized by at least one referee in addition to the editors. About 20% of the contributions to the meetings are not included, either because authors did not wish to publish or because the papers were not accepted by the editors.

Download or read book The Trace Fossil Record of Major Evolutionary Events written by M. Gabriela Mángano and published by Springer. This book was released on 2016-11-17 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume addresses major evolutionary changes that took place during the Mesozoic and the Cenozoic. These include discussions on major evolutionary radiations and ecological innovations on land and at sea, such as the Mesozoic marine revolution, the Mesozoic radiation of vertebrates, the Mesozoic lacustrine revolution, the Cenozoic radiation of mammals, the evolution of paleosol biotas, and the evolution of hominins. The roles of mass extinctions at the end of the Triassic and at the end of the Cretaceous are assessed. This volume set provides innovative reviews of the major evolutionary events in the history of life from an ichnologic perspective. Because the long temporal range of trace fossils has been commonly emphasized, biogenic structures have been traditionally overlooked in macroevolution. However, comparisons of ichnofaunas through geologic time do reveal the changing ecology of organism-substrate interactions. The use of trace fossils in evolutionary paleoecology represents a new trend that is opening a window for our understanding of major evolutionary radiations and mass extinctions. Trace fossils provide crucial evidence for the recognition of spatial and temporal patterns and processes associated with paleoecologic breakthroughs.
