The enormous advances in molecular biology that have been witnessed in . Not recent years have had major impacts on many areas of the biological sciences least of these has been in the field of clinical bacteriology and infectious disease . Molecular Bacteriology: Protocols and ClinicalApplications aims to provide the reader with an insight into the role that molecular methodology has to play in modern medical bacteriology. The introductory chapter ofMolecular Bacteriology: ProtocolsandCli- cal Applications offers a personal overview by a Consultant Medical Microbio- gist of the impact and future potential offered by molecular methods. The next six chapters comprise detailed protocols for a range of such methods . We believe that the use of these protocols should allow the reader to establish the various methods described in his or her own laboratory. In selecting the methods to be included in this section, we have concentrated on those that, arguably, have greatest current relevance to reference clinical bacteriology laboratories; we have deliberately chosen not to give detailed protocols for certain methods, such as multilocus enzyme electrophoresis that, in our opinion, remain the preserve of specialist la- ratories and that are not currently suited for general use. We feel that the methods included in this section will find increasing use in diagnostic laboratories and that it is important that the concepts, advantages, and limitations of each are th- oughly understood by a wide range of workers in the field .

Prokaryotic Toxins - Antitoxins gives the first overview of an exciting and rapidly expanding research field. Toxin - antitoxin (TA) genes were discovered on plasmids 30 years ago. Since then it has become evident that TA genes are highly abundant in bacterial and archaeal chromosomes. TA genes code for an antitoxin that combine with and neutralize a cognate toxin. When activated, the toxins inhibit protein synthesis and cell growth and thereby induce dormancy and multidrug tolerance (persistence). Remarkably, in some species, the TA gene families have undergone dramatic expansions. For example, the highly persistent major human pathogen Mycobacterium tuberculosis has "100 TA loci. The large expansion of TA genes by some organisms is a biological mystery. However, recent observations indicate that TA genes contribute cumulatively to the persistence of bacteria. This medically important phenomenon may thus for the first time become experimentally tractable at the molecular level.

Arbuscular Mycorrhiza (AM) is the most common mycorrhizal type involved in agricultural systems, and the most widespread plant root symbiosis. The fungi involved (Glomales) are known to promote plant growth and health by acting as biofertilizers, bioprotectors and bioregulators. The main aim of this book is to provide readers with theoretical and applied knowledge essential for the use of AM fungi in improving plant health and fitness, production of high quality food and in conservation of natural resources. The different chapters target understanding the role of AM fungi in sustainable crop production, discussing ways to improve biological equilibria between microorganisms in the mycorrhizosphere, analysing genetic, physiological, cellular and molecular bases of AM functioning and establishing technologies for inoculum production, according to the regulatory guidelines for application.

Metabolic engineering has been developed over the past 20 years to become an important tool for the rational engineering of industrial microorganisms. This book has a particular interest in the methods and applications of metabolic engineering to improve the production and yield of a variety of different metabolites. The overall goal is to achieve a better understanding of the metabolism in different microorganisms, and provide a rational basis to reprogram microorganisms for improved biochemical production.

Gaining public attention due, in part, to their potential application as energy storage devices in cars, Lithium-ion batteries have encountered widespread demand, however, the understanding of lithium-ion technology has often lagged behind production. This book defines the most commonly encountered challenges from the perspective of a high-end lithium-ion manufacturer with two decades of experience with lithium-ion batteries and over six decades of experience with batteries of other chemistries. Authors with years of experience in the applied science and engineering of lithium-ion batteries gather to share their view on where lithium-ion technology stands now, what are the main challenges, and their possible solutions. The book contains real-life examples of how a subtle change in cell components can have a considerable effect on cell's performance. Examples are supported with approachable basic science commentaries. Providing a unique combination of practical know-how with an in-depth perspective, this book will appeal to graduate students, young faculty members, or others interested in the current research and development trends in lithium-ion technology.

A general review about industrial processes of Amino Acid production provides a comprehensive overview about recent strain development as well as fermentation technologies. It was our special interest to focus the other articles on the most important and best selling amino acids on the world market i.e. L-Glutamate, L-Lysine and L-Threonine. The authors of this special volume have contributed significantly to the progress of Amino Acid biotechnology in the last decades and earn our special gratitude and admiration for their expert review articles.

Referred to in the Bible, pictured on the wall-friezes of ancient Egyptian tombs, and a subject of fascination for generations of scientists, the tilapias (Cichlidae: Tilapiini) have featured in the diet and culture of humankind for thousands of years. The present century has seen their spread from Africa throughout the tropics and sub-tropics, largely for food and fisheries purposes. This book attempts to pull together our knowledge of this important group - their biology and fisheries and aquaculture - in a single volume, something that has not been done comprehensively for nearly two decades. A succession of chapters by acknowledged authorities covers evolution, phylogenetic relationships and biogeography, reproductive biology, mating systems and parental care, diet, feeding and digestive physiology, environmental physiology and energetics, the role of tilapias in ecosystems, population dynamics and management, genetics, seed production, nutrition, farming, economics and marketing. The book is aimed at biologists, fisheries scientists, aquaculturists, and all interested in aquatic ecology.

This volume covers the fields of origin, evolution and phylogenesis from prokaryotic to eukaryotic cells. The eminent authors, experts in their fields, review the three kingdoms of life (Archea, Eubacteria and Eukarya) from molecular evolutionary levels to ecological aspects in enigmatic habitats, including general reviews of puzzling pro-and eukaryotic organisms and their domains. We discuss dry habitats, thermophilic (cells in hot springs and undersea thermal vents up to 110AC), psychrophilic (cryophiles) and halophilic (high salt concentrations) niches which among the harshest conditions found on Earth where microbial life is frequently detected. Some chapters deal with the organisms which grow in extreme pH conditions (acidity vs. alkalinity), and under hydrostatic pressure in the deep sea, and microbial growth on petroleum. Other contributors present their research on aerobiology and microbes growing in various gases and various levels of radiation, including cellular morphological modification in these extremophilic microbes. This volume also includes the symbiotic association between two or more organisms on the endocellular and exocellular levels. Finally one paper identifies the extremophiles as candidates for exobiology. This is a valuable comprehensive volume in English that covers most of the extremophiles in a new light with current research data. Audience: Students, lecturers and researchers; scholars in the fields of biology, evolutionary biology and chemistry, and other evolutionary fields, and the intelligent layman.

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.

Handbook of Animal Models of Infection is a complete revision of a three-volume text that was published in 1986. It incorporates the major advances in the field during the past decade, in particular those concerning molecular biological procedures and new models that have been developed. It focuses on both methods and techniques, which makes it an essential and comprehensive reference as well as a benchtop manual. The Handbook will help investigators save time and effort in formulating an approach to test a new potential therapeutic agent or combination of agents for "in vivo" efficacy and to position the therapy for specific infections where it may have therapeutic promise. The book is divided into five sections; the first covering the general methodologies, followed by sections describing experimental bacterial, mycotic, parasitic, and viral infections.

* Details a wide range of animals including rodents, rabbits, cats, and primates
* Provides hands-on descriptions of how to set up the model
* Discusses the major advantages and limitations of each model
* Ensures full coverage of bacterial, fungal, viral, and parasitic infections

PCR methods for the detection of microbial pathogens have made relatively little impact in diagnostic microbiology laboratories due to the common decision to use expensive commercially produced tests rather than the cheaper alternative of developing one's own tests or introducing tests developed by other workers. PCR Detection of Microbial Pathogens, Second Edition presents alternatives to commercially produced PCR methods to detect microbial pathogens. Although most of the chapters in this book are devoted to the detection of specific pathogens, the first chapters in this book should appeal to anyone working in this field regardless of their particular interests. Although PCR tests can often be made to work with relatively little effort, it is often unclear how efficient the PCR test is, how inhibitory the specimen containing the pathogen of interest is and how the test can be quality controlled. All of which are of great importance in developing tests for diagnostic use. These topics are covered in great depth at the beginning of the book. The main part of the book is devoted to describing methods for the detection of a wide range of pathogens and from widely different specimens and situations. Written in the highly successful Methods in Molecular Biology (TM) series format, chapters contain introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and accessible, PCR Detection of Microbial Pathogens, Second Edition serves microbiologists regardless of their particular interest because, when used together with the general principles, the sheer variety of procedures provided here enables the reader to design and introduce diagnostic tests in the laboratory with confidence.

* Examines the importance of genetically stable cultures as it relates to maintaining patent positions

Biological nitrogen fixation (BNF) has become important in rice farming systems because this process diminishes the need for expensive chemical fertilizers which have been associated with numerous health and environmental problems. The extensive exploitation of BNF would provide economic benefits to small farmers, avoiding all malign influences of chemical fertilizers. Meanwhile, advances in biotechnology have brought rice genetics to the threshold of new opportunities for increasing rice production. This volume focuses, in six different sessions, on the role of BNF in the improvement of rice production in the light of the current state of the art of BNF technology transfer and diffusion. New ideas on BNF technology in research, extension information and inoculant technology are also included, together with the socio-economic impacts of using BNF in rice farm systems.

Researchers in the field of ecological genomics aim to determine how a genome or a population of genomes interacts with its environment across ecological and evolutionary timescales. Ecological genomics is trans-disciplinary by nature. Ecologists have turned to genomics to be able to elucidate the mechanistic bases of the biodiversity their research tries to understand. Genomicists have turned to ecology in order to better explain the functional cellular and molecular variation they observed in their model organisms.

We provide an advanced-level book that covers this recent research and proposes future development for this field. A synthesis of the field of ecological genomics emerges from this volume."Ecological Genomics"covers a wide array of organisms (microbes, plants and animals) in order to be able to identify central concepts that motivate and derive from recent investigations in different branches of the tree of life.

"Ecological Genomics"covers 3 fields of research that have most benefited from the recent technological and conceptual developments in the field of ecological genomics: the study of life-history evolution and its impact of genome architectures; the study of the genomic bases of phenotypic plasticity and the study of the genomic bases of adaptation and speciation.

Although virology and immunology are now considered separate disciplines, history shows that these areas ofinvestigation always overlapped and one cannot really exist without the other. This trend has become particularly significant and fruitful in the past few years in the area of herpesvirus research. The genomes of the most important herpesviruses have been sequenced, a significant portion of their genes have been identified, and many secrets of regulation of gene expr- sion have been unraveled. Now this progress sets the stage for a true revolution in herpesvirus research: analysis of interactions between the host and the virus. Because herpesviruses can induce, suppress, and fool the immune system, the most productive herpesvirologists are also expert immunologists, and the current results ofthis interdisciplinary effort are truly remarkable. Because herpesviruses cause many important human diseases, the devel- ment of vaccines against these agents is a very significant goal. This effort is also very challenging because of the complexity of herpesviruses and the lack of sufficient information about immune responses. The remarkable ability of herpesviruses to escape immune responses is - other feature that brings immunology and virology together. Herpesviruses - code many proteins that interact with and down-regulate some key elements of the immune system. Thisproperty of herpesviruses represents amajor challenge in developing strategies against these viruses. On the positive side, these viral proteins also provide novel tools for analyzing specific immune reactions and molecular mechanisms.

The symposium, "Microbial Diversity in Time and Space," was held in the Sanjo Conference Hall, University of Tokyo, Tokyo, Japan, October 24-26, 1994. The symposium was organized under the auspices of the Japanese Society of Microbial Ecology and co-sponsored by the International Union of Biological Sciences (IUBS), International Union of Microbiological Societies (IUMS), International Committee on Microbial Ecology (ICOME), and the Japanese Society of Ecology. The aim of the symposium was to stress the importance of the global role of microorganisms in developing and maintaining biodiversity. Twenty-four speakers from seven countries presented papers in the symposium and in the workshop, "Microbial Diversity and Cycling of Bioelements," that followed the symposium. Papers presented at the symposium are published in this proceedings. Discussions of the workshop, which were energetic and enthusiastic, are also summarized in this proceedings. The symposium provided an opportunity to address the role of microorganisms in global cycles and as the basic support ofbiodiversity on the planet. Previously unrecognized as both contributing to and sustaining biodiversity, microorganisms are now considered to be primary elements of, and a driving force in, biodiversity. Financial support was provided for the symposium by the CIBA GEIGY Foundation for the Promotion of Science, Naito Foundation, and the Uchida Foundation of the Ocean Research Institute, University of Tokyo. Support from these foundations is gratefully acknowledged. CONTENTS Microbial Biodiversity-Global Aspects ................................. 1 Rita R. Colwell 2.

The use of renewable bioenergy is increasing, and so is the production of associated wastes: biomass ashes. This book presents eleven chapters on the options for recycling such biomass ashes, ranging from their use as fertilizer in agriculture and forestry to their application as a supplement for the production of cement-based materials or bricks. The book also examines the pros and cons for each of the different uses of biomass ashes.

Plant conservation is increasingly recognised as an outstanding global priority, yet despite considerable efforts over the last few decades, the number of threatened species continues to rise. The practice of plant conservation has for too long been a rather hit-or-miss mixture of methods. While microorganisms have been recognised as a crucial and essential element in supporting the lifecycles of plant species, there has been limited recognition of the relationships between macro level conservation facilitating ecosystem functioning at the micro level.

This book addresses the role of microorganisms in conservation - both their support functions and deleterious roles in ecosystem processes and species survival. Importantly, a number of authors highlight how microbial diversity is, itself, now under threat from the many and pervasive influences of man. What is clear from this volume is that like many contemporary treatments of plant and animal conservation, the solution to mitigate the erosion of biodiversity is not simple. This book represents an attempt to bring to the fore the ecological underwriting provided by microorganisms.

The tetracyclines have an illustrious history as therapeutic agents which dates back over half a century. Initially discovered as an antibiotic in 1947, the four ringed molecule has captured the fancy of chemists and biologists over the ensuing decades. Of further interest, as described in the chapter by George Armelagos, tetracyclines were already part of earlier cultures, 1500-1700 years ago, as revealed in traces of drug found in Sudanese Nubian mummies. The diversity of chapters which this book presents to the reader should illus trate the many disciplines which have examined and seen benefits from these fascinating natural molecules. From antibacterial to anti-inflammatory to anti autoimmunity to gene regulation, tetracyclines have been modified and redesigned for various novel properties. Some have called this molecule a biol ogist's dream because of its versatility, but others have seen it as a chemist's nightmare because of the synthetic chemistry challenges and "chameleon-like" properties (see the chapter by S. Schneider).

This Volume provides protocols for the biochemical analysis of hydrocarbon- and lipid-relevant products, cell components and activities of microbes that interact with hydrophobic compounds. They include methods for the extraction, purification and characterisation of surface tension-reducing bioemulsifiers and biosurfactants that increase the surface area and hence bioavailability of hydrophobic substrates. Protocols for the isolation and biochemical analysis of lipids and polyhydroxyalkanoates, food storage products made during nutrient abundance that represent important biotechnological products, are presented. The extraction of membrane lipid rafts, sub-organelles that fulfil important functional roles for the cell membrane, and the isolation and characterisation of membrane phospholipid biomarkers, are also described. The purification and characterisation of integral membrane hydrocarbon-oxidising enzymes are addressed. Lastly, two generic methods for the genetic analysis of catabolic pathways and analysis of ligand binding are presented. Hydrocarbon and Lipid Microbiology ProtocolsThere are tens of thousands of structurally different hydrocarbons, hydrocarbon derivatives and lipids, and a wide array of these molecules are required for cells to function. The global hydrocarbon cycle, which is largely driven by microorganisms, has a major impact on our environment and climate. Microbes are responsible for cleaning up the environmental pollution caused by the exploitation of hydrocarbon reservoirs and will also be pivotal in reducing our reliance on fossil fuels by providing biofuels, plastics and industrial chemicals. Gaining an understanding of the relevant functions of the wide range of microbes that produce, consume and modify hydrocarbons and related compounds will be key to responding to these challenges. This comprehensive collection of current and emerging protocols will facilitate acquisition of this understanding and exploitation of useful activities of such microbes.
