Download or read book Characterization of a Yellowstone Hot Spring Microbial Community by 5S RRNA Sequences written by David Allan Stahl and published by . This book was released on 1985 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: The microorganisms inhabiting a 91 degrees C hot spring in Yellowstone National Park were characterized by sequencing 5S rRNAs isolated from the mixed, natural microflora without cultivation. By comparisons of these sequences with reference sequences, the phylogenetic relationships of the hot spring organisms to better characterized ones were established. Quantitation of the total 5S-sized rRNAs revealed a complex microbial community of three dominant members, a predominant archaebacterium affiliated with the sulfur-metabolizing (dependent) branch of the archaebacteria, and two eubacteria distantly related to Thermus spp. The archaebacterial and the eubacterial 5S rRNAs each constituted about half the examined population.
Download or read book Thermophiles Biodiversity Ecology and Evolution written by Anna-Louise Reysenbach and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: These are indeed exciting times to be a microbiologist. With one of the buzzwords of the past decade-"Biodiversity," and microbes are reveling in the attention as they represent by far most of the biodiversity on Earth. Microbes can thrive in almost any environment where there is an exploitable energy source, and, as a result, the possible existence of microbial life elsewhere in the solar system has stimulated the imaginations of many. Extremophiles have taken center stage in these investigations, and thermophiles have taken on the lead roles. Consequently, in the past decade there has been a surge of interest and research in the Ecology, Biology, and Biotechnology of microorganisms from thermal environments. Many of the foundations of thermophile research were laid in Yellowstone National Park, primarily by the research of Professor Thomas Brock's laboratory in the late 1960s and early 1970s. The upper temperature for life was debated, the first thermophilic archeum discovered (although it was only later shown to be an archeum by ribosomal cataloging), and the extremes of light, temperature, pH on the physiology of microorga nisms were explored. Interest in thermophiles increased steadily in the 1970s, and with the discovery of deep-sea hydrothermal vents in 1977, thermophilic research began its expo nential explosion. The development of Taq polymerase in the polymerase chain reaction (peR) focused interest on the biotechnological potential of thermophilic microorganisms and on the thermal features in Yellowstone National Park.
Download or read book Molecular Microbial Ecology written by Mark Osborn and published by Garland Science. This book was released on 2004-06-02 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microoganisms are distributed across every ecosystem, and microbial transformations are fundamental to the operation of the biosphere. Microbial ecology is the study of this interaction between microorganisms and their environment, and arguably represents one of the most important areas of biological research. Yet for many years our study of microbial flora was severely limited: the primary method of culturing microorganisms on media allowed us to study only between 0.1 and 10% of the total microbial flora in any given environment. Molecular Microbial Ecology gives a comprehensive guide to the recent revolution in the study of microorganisms in the environment. Details are given on molecular methods for isolating some of the previously uncultured and numerically dominant microbial groups. PCR-based approaches to studying prokaryotic systematics are described, including ribosomal RNA analysis and stable isotope probing. Later chapters cover DNA hybridisation techniques (including fluorescent in situ hybridisation), as well as genomic and metagenomic approaches to microbial ecology. Gathering together some of the world’s leading experts, this book provides an invaluable introduction to the modern theory and molecular methods used in studying microbial ecology.

Download or read book Molecular Approaches to the Study of the Ocean written by K.E. Cooksey and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 562 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine biological science is now studied at the molecular level and although research scientists depend on information gained using molecular techniques, there is no book explaining the philosophy of this approach. Molecular Approaches to the Study of the Ocean introduces the reasons why molecular technology is such a powerful tool in the study of the oceans, describing the types of techniques that can be used, why they are useful and gives examples of their application. Molecular biological techniques allow phylogenetic relationships to be explored in a manner that no macroscopic method can; although the book deals with organisms near the base of the marine food web, the ideas can be used in studies of macroorganisms as well as those in freshwater environments.
Download or read book The Tangled Tree written by David Quammen and published by Simon & Schuster. This book was released on 2019-08-06 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this New York Times bestseller and longlist nominee for the National Book Award, “our greatest living chronicler of the natural world” (The New York Times), David Quammen explains how recent discoveries in molecular biology affect our understanding of evolution and life’s history. In the mid-1970s, scientists began using DNA sequences to reexamine the history of all life. Perhaps the most startling discovery to come out of this new field—the study of life’s diversity and relatedness at the molecular level—is horizontal gene transfer (HGT), or the movement of genes across species lines. It turns out that HGT has been widespread and important; we now know that roughly eight percent of the human genome arrived sideways by viral infection—a type of HGT. In The Tangled Tree, “the grandest tale in biology….David Quammen presents the science—and the scientists involved—with patience, candor, and flair” (Nature). We learn about the major players, such as Carl Woese, the most important little-known biologist of the twentieth century; Lynn Margulis, the notorious maverick whose wild ideas about “mosaic” creatures proved to be true; and Tsutomu Wantanabe, who discovered that the scourge of antibiotic-resistant bacteria is a direct result of horizontal gene transfer, bringing the deep study of genome histories to bear on a global crisis in public health. “David Quammen proves to be an immensely well-informed guide to a complex story” (The Wall Street Journal). In The Tangled Tree, he explains how molecular studies of evolution have brought startling recognitions about the tangled tree of life—including where we humans fit upon it. Thanks to new technologies, we now have the ability to alter even our genetic composition—through sideways insertions, as nature has long been doing. “The Tangled Tree is a source of wonder….Quammen has written a deep and daring intellectual adventure” (The Boston Globe).

Download or read book Stress Biology of Cyanobacteria written by Ashish Kumar Srivastava and published by CRC Press. This book was released on 2013-03-01 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: A significant component of many different ecosystems, cyanobacteria occupy almost every niche of the earth, including fresh and salt waters, rice fields, hot springs, arid deserts, and polar regions. Cyanobacteria, along with algae, produce nearly half the global oxygen, making assessment of their ecophysiologies important for understanding climate impacts and potential remediation. Stress Biology of Cyanobacteria: Molecular Mechanisms to Cellular Responses is a compilation of holistic responses of cyanobacteria, ranging from ecological and physiological to the modern aspects of their molecular biology, genomics, and biochemistry. Covering almost every aspect of cyanobacterial stress biology, this book is divided into two parts: Bioenergetics and Molecular Mechanisms of Stress Tolerance and Cellular Responses and Ecophysiology. The first few chapters focus on the molecular bioenergetics of photosynthesis and respiration in cyanobacteria, and provide a clear perspective on different stress tolerance mechanisms. Part I also covers the effect of specific stresses—including heavy metal, high and low temperature, salt, osmotic, and UV-B stress—on a wide range of vital physiological, biochemical, and molecular processes of cyanobacteria. Part II describes mechanisms of symbiosis, stress-induced bioproducts, and the role of environmental factors on nitrogen fixation, which along with photosynthesis is a major contributor to the current geochemical status of the planet. The text also covers mutation and cyanobacterial adaptation, and the most widely studied cyanotoxin, microcystin, which has effects on both human and animal health. With contributions from experts around the world, representing the global importance of cyanobacteria, this book provides a broad compilation of research that deals with cyanobacterial stress responses in both controlled laboratory conditions as well as in their natural environment.

This book was released on 2013-03-13 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume represents a collection of pioneering papers introducing immunochemical techniques to the aquatic sciences. It is the product of a workshop entitled "Immunochemical Approaches to Coastal, Estuarine and Oceanographic Questions" held at the University of Southern Maine, Portland, Oct. 5-7, 1986. Funding from many sources made this workshop possible, and is gratefully acknowledged. The reader will note great variability in both the quality and scope of the papers which we have divided 'into four sections: I. Background material on the immune system (borrowed from a recent NIH publication) II. Background material related to aquatic sciences III. Techniques IV. Applications Readers familiar with terminology are directed to start with the original contributions related to aquatic sciences, page 21. Some of the contributions are abstracts only. Others are preliminary, for which we are grateful to the authors for their willingness to share recent sometimes tentative findings with a broader community. Some offer novel and tempting insights, but as they exist, lack adequate standards and controls. Others are thorough and represent major scientific contributions. The promise rests in generating and working with reagents of great specificity enabling orders of magnitude improvements in the sensitivity of our measurements. Authors also address the problems and limitations. We thank the numerous authors and reviewers. In support of every successful endeavor is someone of unusual savvy. For us, this has been David A. Phinney. His leadership, wisdom and wit have been important to the introduction of flow cytometry/sorting and immunochemistry into aquatic research.
