Microbial Physiology retains the logical, easy-to-follow organization of the previous editions. An introduction to cell structure and synthesis of cell components is provided, followed by detailed discussions of genetics, metabolism, growth, and regulation for anyone wishing to understand the mechanisms underlying cell survival and growth. This comprehensive reference approaches the subject from a modern molecular genetic perspective, incorporating new insights gained from various genome projects. The major objective of this book is to identify and focus attention on those methods and concepts that contribute to an understanding of organismal or genetic persistence. In addition, information about microbial physiology, genetics and ecology contributing to persistence of microorganisms or the measurement of persistence will be discussed. Consequently, there is a great need for more baseline information concerning the ecology of microbes in the natural environment. In determining the underlying risks associated with the release of genetically engineered microorganisms, both the target of risk and the critical exposure level must be identified.
This new textbook offers an introduction to microbial physiology for students with a background in microbiology, physiology and biochemistry.
Based on the thesis that insights into both evolution and ecology can be obtained through the study of microorganismsm, Microbial Ecology examines microbiology through the lens of evolutionary ecology. Measured from a microbial perspective, this text covers such topics as optimal foraging, genome, reduction, novel evolutionary mechanisms, bacterial speciation, and r and K selection. Numerous aspects of microbial existence are also discussed and include: species competition, predation, parasitism, mutualism, microbial communication through quorum sensing and other. The result is a context for understanding microbes in nature and a framework for microbiologists working in industry, medicine, and the environment. Applies evolutionary ecological concepts to microbes Addresses individual, population and community ecology Presents species concepts and offers insights on the origin of life and modern microbial ecology Examines topics such as species interactions, nutrient cycling, quorum sensing and cheating
This book gives an overview of gene transfer and stability in those aquatic and terrestrial environments where bacteria and fungi can survive and interact genetically. It examines the role played by sex between microbes in the evolution of populations and their survival. Special emphasis is placed on methodology, including the analysis by novel techniques of genetic material extracted directly from soils, rivers and lakes. The natural spread of antibiotic resistance and the safe use of genetically manipulated microbes are matters of considerable scientific, medical and public concern upon which the investigations presented here have direct bearing. This unique collection will be of value to specialist researchers in applied microbiology, ecology and biotechnology as well as biomedical scientists interested in the environmental risks of genetic engineering.
Since the general recognition of the Archaebacteria, research into the evolution, metabolism, molecular biology and ecological roles of these fastidious anaerobes has proceeded at an ever-increasing pace. All possess a very novel biochemistry and many exploit unique ecological niches. Methanogens, which convert one-and-two carbon compounds into the important atmospheric gas methane, are the largest group among the Archaebacteria. Of all microbial groups, methanogens provide perhaps the best opportunity to study evolution because of their phyologenetic diversity and unique biochemistry. Today, the analysis of methanogens is at a threshold. Molecular-biological studies of these microorganisms are revealing more and more processes unique to this group, and in turn, studies of methanogens are providing new perspectives to the broader fields of biochemistry and molecular biology. This volume is the first book to be published on methanogenesis, and it will provide the reader with a comprehensive view of the field and point to future trends.
Advances in Microbial Physiology
This book has arisen from the Second European Meeting on Bacterial Genetics and Ecology (Bageco-2) held at the University of Wales, College of Cardiff which we organised on 11-12 April 1989. The meeting was attended by some 60 participants from eight European countries and was made possible by partial financial support from the Commission of the European Communities (CEC) and Imperial Chem ical Industries (UK) Ltd. The meeting was organised to discuss modern developments in the genetics of bacteria in aquatic and terrestrial habitats. It followed on from, and complemented, the first meeting of this series organised by Jean-Pierre Gratia in Brussels during April 1987 which concentrated more on medical and epidemiological issues. ! The next meeting will be organised by Michel J. Gauthier in 1991 at Nice, France. If you have been fired with enthusiasm for ecological bacterial genetics after having read this book, and want to attend the next meeting but did not hear about the one in Cardiff, you should write to Dr Gauthier to be put on the address list. A lot is now known about bacterial genetics at the physiological, biochemical and molecular level, and bacterial ecology has developed rapidly over the last 20 years. However, until very recently, few researchers have crossed the divide and linked these two specialisms.
Dr. Joshua Lederberg - scientist, Nobel laureate, visionary thinker, and friend of the Forum on Microbial Threats - died on February 2, 2008. It was in his honor that the Institute of Medicine's Forum on Microbial Threats convened a public workshop on May 20-21, 2008, to examine Dr. Lederberg's scientific and policy contributions to the marketplace of ideas in the life sciences, medicine, and public policy. The resulting workshop summary, Microbial Evolution and Co-Adaptation, demonstrates the extent to which conceptual and technological developments have, within a few short years, advanced our collective understanding of the microbiome, microbial genetics, microbial communities, and microbe-host-environment interactions.
