Bacteria occupy a unique position in the living world. They are amongst the first inhabitants of planet earth, and have survived until the present day. Adaptation, adjustment, and accommodation are the hallmarks of their strategy for survival. Their structural simplicity, and yet independent lifestyle, has provided a baseline model system on which every branch of modern biology have been founded. This includes the fields of molecular genetics and recombinant DNA technology. Bacteria have been at the heart of developments in the field of biotechnology where today many microbial and eukaryotic (including human) metabolites have found industrial applications. Amenable to all modern tools and techniques, bacteriology has developed an interface with all other branches of biology, often providing the major leads and clues. In the present era of genomics, now that many microbial genomes have been sequenced, bacteria are destined to provide new information that will further our understanding of life and biological processes.
This book contains exhaustive information on almost all aspects of bacteria. The book deals exclusively with bacteria and includes the entire gamut of bacteriology. It will be useful to graduate and post-graduate levels but also to established researchers. The book is organized in such a way that it will give the reader an overview of our current understanding of bacteria. It will explain the categories under which various types have been grouped and describe the versatile range of metabolic processes which can be found in these microbial organisms. Their metabolic regulation, capacity to change and keep evolving and their pivotal role in natural processes arehighlighted. Research on bacteria, especially genetic engineering, will have far reaching applications in the future.

"Biodegradative Bacteria" highlights the novel nature of bacterial cell functions in the field of biodegradation by putting them into three parts: (1) Genetic and genomic systems, (2) Degradative enzyme systems, and (3) Bacterial behavior in natural environmental systems. The first part of the book includes cell functions as degradative machinery, genome systems for effective degradation, and the evolution of degradative systems by mobile genetic elements. The second part deals with the structure, function, evolution, diversity, and application of degradative and related enzymes. The third part presents cell or genomic behaviors of biodegradative bacteria in natural ecosystems.

Bacterial metabolic capacity, which plays an important role in the global material cycle, contributes significantly to the buffering capacity for the huge and unintended release of various chemicals. Recently, however, the prosperity and globalization of material civilization has led not only to severe local contamination by hazardous chemicals, but also to continuous increment of contaminant concentrations worldwide. To solve such urgent global issues, bacterial functions that are involved in biodegradation of hazardous chemicals have been analyzed. The term biodegradative bacteria refers to those bacteria that have the ability to degrade such xenobiotic (man-made) and/or hazardous chemicals. Analyses of biodegradative bacteria include diverse areas of study, such as genetics, enzymology, genomics, cell physiology, ecology, and evolutionary biology. In other words, the targets investigated in research on biodegradative bacteria include single molecules, single cell systems, bacterial consortia (interaction with surrounding microorganisms), and interaction with surrounding biotic and abiotic materials. Such complexity makes the research on biodegradative bacteria difficult but quite interesting."

This book explores the broad and diverse biological and physiological impacts of established and newly discovered cyclic di-nucleotide second messenger signaling systems, while also providing descriptions of the intriguing biochemical characteristics of multiple turnover enzymes and receptors. The respective chapters discuss the commonalities and diversity of cyclic di-GMP, cyclic di-AMP and recently discovered cyclic GMP-AMP signaling systems in manifold Gram-negative and Gram-positive bacteria. The global human pathogens Mycobacterium tuberculosis, Vibrio cholerae, Salmonella typhimurium, Escherichia coli and Streptococcus pneumoniae, the facultative human pathogen Pseudomonas aeruginosa, global plant pathogens as exemplified by Xanthomonas campestris and Burkholderia spp., and the omnipresent probiotic Lactobacilli, as well as environmentally important photoautotrophic cyanobacteria, the multicellular Myxococcus xanthus, and chemolithotrophic Acidithiobacillus are among the representatives of the microbial kingdom that are described. In turn, the various aspects of bacterial physiology affected by these signaling systems- e.g. biofilm formation and dispersal, the cell cycle, motility, virulence, production of antimicrobials, fundamental metabolism and osmohomeostasis - are discussed in detail in the context of different microorganisms. Dedicated chapters focus on the population diversity of cyclic dinucleotide signaling systems, their tendency to be horizontally transferred, the cyclic di-GMP signaling system in the social amoeba Dictyostelium, honorary cyclic (di)nucleotides, and the development of strategies for interfering with cyclic dinucleotide signaling in order to manipulate microbial behavior. Taken together, the chapters provide an authoritative source of information for a broad readership: beginners and advanced researchers from various disciplines; individuals seeking a broad overview of cyclic di-nucleotide signaling; and those who want to learn more about specific aspects. Also featuring reviews with a forward-looking perspective, the book offers a valuable source of inspiration for future research directions.

Gene regulation at the transcriptional level is central to the process by which organisms convert the constant sensing of environmental changes and intracellular fluzes of metabolites to homeostatic responses. Along with the strategic guidance of M. Madan Babu authors from around the world have joined forces to review and discuss the latest research observations and current theories in this highly topical and important area of microbiology.

This Microbiology Monographs volume covers the latest advances in laccase applications in bioremediation and waste valorisation. The first three chapters provide a comprehensive introduction to fungal and bacterial laccases (the two most important enzyme groups from an application viewpoint) and their practical use in bioremediation and lignocellulosic waste valorisation. Subsequent chapters discuss possible combinations of laccases and further potentially collaborating enzymes, and offer in-depth insights into laccase immobilisation for wastewater treatment and environmental biosensor applications of laccases. Lastly, the book addresses the quest for enzymes with improved and better-fitting properties, covering laccase engineering by directed and computational evolution, and novel enzymes from extreme environments. As such, it is a fascinating read for microbiologists in both industry and academia.

In this work, experts review the latest research in the bioremediation of mercury, including the genetic engineering of bacteria and plants.

Combining the disciplines of biological, physical and chemical science, microbial forensics has a rapidly rising profile in a world increasingly troubled by the threat of 'biocrime' and 'bioterrorism'. This valuable resource is a major addition to a body of literature reckoned to lack sufficient breadth. It presents a variety of phenotypic and trace signature methodologies associated with cultured microorganisms that, despite being genetically identical, may be characterized by differing cultural environments. One of the central challenges faced by those working in this field is the sheer diversity of potentially harmful agents, which in themselves total more than 1000 viruses, bacteria, fungi and protozoan parasites. Their numerous additional variants render the process of 'fingerprinting' biological agents notoriously difficult, especially when the limitations of genetic analysis are factored in. Attribution of crime is relatively easy through human DNA, but lacking the genetic individuation of humans and animals, microbial forensics has to complement phylogenetic techniques with chemical and physical ones. In the best case, genetic analysis in the 'biocrime' sector can exclude sources, narrow the population of possible sources and support associations with potential sources. To complement these genetic techniques, chemical and physical methods can be used to compare 'signatures' imparted to microbial samples by environments in which they are grown and processed. Collating a range of microbiological fingerprinting techniques in one volume, and covering everything from statistical analysis to laboratory protocols, this publication furthers the aim of forensic investigators who need robust and legally admissible forensic evidence to present in a courtroom.

This book details the widely accepted hypothesis that the majority of bacteria in virtually all ecosystems grow in matrix-enclosed biofilms. The author, who first proposed this biofilm hypothesis, uses direct evidence from microscopy and from molecular techniques, arguing cogently for moving beyond conventional culture methods that dominated microbiology in the last century. Bacteria grow predominantly in biofilms in natural, engineered, and pathogenic ecosystems; this book provides a solid basis for the understanding of bacterial processes in environmental, industrial, agricultural, dental and medical microbiology. Using a unique "ecological" perspective, the author explores the commensal and pathogenic colonization of human organ systems.

This book explains the metabolic processes by which microbes obtain and control the intracellular availability of their required metal and metalloid ions. The book also describes how intracellular concentrations of unwanted metal and metalloid ions successfully are limited. Its authors additionally provide information about the ways that microbes derive metabolic energy by changing the charge states of metal and metalloid ions. Part one of this book provides an introduction to microbes, metals and metalloids. It also helps our readers to understand the chemical constraints for transition metal cation allocation. Part two explains the basic processes which microbes use for metal transport. That section also explains the uses, as well as the challenges, associated with metal-based antimicrobials. Part three gives our readers an understanding that because of microbial capabilities to process metals and metalloids, the microbes have become our best tools for accomplishing many jobs. Their applications in chemical technology include the design of microbial consortia for use in bioleaching processes that recover metal and metalloid ions from industrial wastes. Many biological engineering tasks, including the synthesis of metal nanoparticles and similar metalloid structures, also are ideally suited for the microbes. Part four describes unique attributes associated with the microbiology of these elements, progressing through the alphabet from antimony and arsenic to zinc.

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.

Concerted efforts to study starvation and survival of nondifferentiating vegeta tive heterotrophic bacteria have been made with various degrees of intensity, in different bacteria and contexts, over more than the last 30 years. As with bacterial growth in natural ecosystem conditions, these research efforts have been intermittent, with rather long periods of limited or no production in between. While several important and well-received reviews and proceedings on the topic of this monograph have been published during the last three to four decades, the last few years have seen a marked increase in reviews on starvation survival in non-spore-forming bacteria. This increase reflects a realization that the biology of bacteria in natural conditions is generally not that of logarithmic growth and that we have very limited information on the physiology of the energy-and nutrient-limited phases of the life cyde of the bacterial cello The growing interest in nongrowing bacteria also sterns from the more recent advances on the molecular basis of the starvation-induced nongrowing bacterial cello The identification of starvation-specific gene and protein re sponders in Escherichia coli as weIl as other bacterial species has provided molecular handles for our attempts to decipher the "differentiation-like" responses and programs that nondifferentiating bacteria exhibit on nutrient limited growth arrest. Severallaboratories have contributed greatly to the progress made in life after-log research."

Symbiotic associations are of great importance in agriculture and forestry, especially in plant nutrition and plant cultivation. This book provides an up-to-date and lucid introduction to the subject. The emphasis is on describing the variety of symbiotic relationships and their agricultural and environmental applications.

The success of laboratory experiments relies heavily on the technical ability of the bench scientist, with the aid of "tricks-of-the-trade", to generate consistent and reliable data. Regrettably, however, these invaluable "tricks-of-the-trade" are frequently omitted from scientific publications. This paucity of practical information relating to the conduct of laboratory bacteriology experiments creates a gaping void in the pertinent literature.
Methods in Practical Laboratory Bacteriology fills this void. It provides detailed technical information that ensures that you achieve consistent and reliable data. The book addresses the aspects of bacterial fractionation and membrane characterization, the analysis of Lipopolysaccharides and the techniques of SDS-PAGE, immunoblotting, and ELISA. It also describes the methods used for detecting and quantifying bacterial resistance to antibiotics, and the analysis of bacterial chromosomes by pulsed-field gel electrophoresis (PFGE). Methods in Practical Laboratory Bacteriology also covers protocols for extracting the fingerprinting plasmids, as well as the use of non-radio labeled gene probes and ribosomal RNA gene probes.

Each volume in the series focuses on a particular taxon, presenting detailed and reliable ecotoxicological results from both laboratory and field experiments, performed for a comprehensive range of chemicals. A taxonomical guide to the species is given, together with relevant biological and ecological information.
In recent times much attention has been focused on the effects of anthropogenic emissions of chemicals. This series is unique in providing a considered estimate of the potential impact of such chemicals on the environment.
"Ecotoxicity of Chemicals to Photobacterium Phosphoreum" is the second volume in the series "Handbooks of Ecotoxicological Data."

An advantage of this book is that it contains many hitherto unpublished results which

The future of agriculture strongly depends on our ability to enhance productivity without sacrificing long-term production potential. An ecologically and economically sustainable strategy is the application of microorganisms, such as the diverse bacterial species of plant growth promoting bacteria (PGPB). The use of these bio-resources for the enhancement of crop productivity is gaining worldwide importance.

""Bacteria in Agrobiology: Plant Probiotics"" discusses the current trends and future prospects of beneficial microorganisms acting as Probiotics. Topics include the application for the aboveground fitness of plants, in mountain ecosystems, in tropical and Mediterranean forests, and in muga sericulture. Further aspects are "Arabidopsis" as a model system for the diversity and complexity of plant responses, plant parasitic nematodes, nitrogen fixation and phosphorus nutrition."

Bacteriophages (viruses that infect bacteria) are fascinating organisms that have played and continue to play a key role in bacterial genetics and molecular biology. Phage can confer key phenotypes on their host for example, converting a non-pathogenic strain into a pathogen and they play a key role in regulating bacterial populations in all sorts of environments. The phage-bacterium relationship varies enormously, from the simple predator-prey model to a complex, almost symbiotic relationship that promotes the survival and evolutionary success of both. While infection of bacteria used in the fermentation industry can be very problematic and result in financial losses, in other scenarios, phage infection of bacteria can be exploited for industrial and/or medical applications. Interest in phage and phage gene products as potential therapeutic agents is increasing rapidly and is likely to have a profound impact on the pharmaceutical industry and biotechnology in general over the comi

Foods fermented with lactic acid bacteria are an important part of the human diet. Lactic acid bacteria play an essential role in the preservation of food raw materials and contribute to the nutritional, organoleptic, and health properties of food products and animal feed. The importance of lactic acid bacteria in the production of foods throughout the world has resulted in a continued scientific interest in these micro-organisms over the last two decades by academic research groups as well as by industry. This research has resulted in a number of important scientific breakthroughs and has led to new applications. The most recent of these advances is the establishment of the complete genome sequences of a number of different lactic acid bacterial species.

To communicate and stimulate the research on lactic acid bacteria and their applications, a series of tri-annual symposia on lactic acid bacteria was started in 1983 under the auspices of the Netherlands Society for Microbiology (NVVM), which was later also supported by the Federation of European Microbiological Societies (FEMS). The aim of these state-of-the-art symposia is to offer a unique platform for universities, institutes, and industry in this area of biotechnology, to present recent work, to obtain information on new developments, and to exchange views with colleagues from all over the world on scientific progress and applications. The growing number of participants at these symposia has been a clear demonstration of the interest of the international industrial and scientific community in this area of research.

The 7th Symposium is based on a number of plenary lectures that review the scientific progress of the last years in the different areas of research on lactic acid bacteria, and which are documented in this special issue of Antonie van Leeuwenhoek.

Genetic investigations and manipulations of bacteria and bacteriophage have made vital contributions to our basic understanding of living cells and to the development of molecular biology and biotechnology. This volume is a survey of the genetics of bacteria and their viruses, and it provides students with a comprehensive introduction to this rapidly changing subject. The book is written for upper level undergraduates and beginning graduate students, particularly those who have had an introductory genetics course.

The fifth edition has been extensively revised to reflect recent advances in the field. The book now has a reader-friendly look, with end-of-chapter questions, "Thinking Ahead" and "Applications" boxes to challenge students comprehension and insights. A complete glossary of commonly used terms has been revised and expanded.

Over the last decade, interest in mycoplasmas has been greatly sti- lated by the spread of contagious bovine pleuropneumonia (CBPP), caused by Mycoplasma mycoides subsp. mycoides SC, in Europe and Africa and the discovery of a possible association between mycoplasmas and AIDS. During this period there has also been a recognition by control authorities and int- national organizations, including the Office International des Epizooties, that mycoplasmas are major causes of economic loss in livestock and continue to be a problem in humans as a result of a range of chronic respiratory and urogenital diseases. However, it is likely that the true significance of my- plasmas is still underestimated because of the difficulties in working with these extremely fastidious microorganisms. Advances in such laboratory technology as DNA amplification has enabled the detection of unrecoverable mycoplasmas in tissue samples and this will provide us with a better understanding of their role in disease. Important developments have also been seen in more conv- tional areas such as serological tests and media formulation enabling improved recovery and identification. Mycoplasma Protocols provides in a single volume up-to-date and easy-- follow methods for the detection, isolation, identification, and characterization of mycoplasmas, with a major emphasis on those of medical and veterinary significance. It also includes biochemical, genetic, and molecular techniques that will form the basis of understanding pathogenicity and, particularly, - hesion to host cells.

Entomopathogenic bacteria (Bacillus thuringiensis and B. sphaericus) are increasingly used as biopesticides to control larval insect populations which are either agricultural or forestry pests and to reduce those which as adults are vectors of severe human diseases. This new book, the first since 1993 to address all aspects of entomopathogenic bacteria, provides undergraduate and graduate students as well as research scientists with a complete, modern view of this important group of bacteria. The authors, chosen for their sustained contributions to the field, cover both fundamental and applied research in this area. The main topics include bacterial ecology and taxonomy, toxin diversity, activity and mode of action, regulation and environment of the genes, safety and ecotoxicology, production and field application of the bacteria, and outbreaks of resistant populations. The book concludes with the most recent data obtained on transgenic biotechnology and addresses environmental impact issues.

This book is a collection of scholarly articles presenting the research results of work carried out under the supervision of Prof. Saroj Bhosle, a microbiologist at Goa University, India.The objective of this volume is to document the comprehensive ecological knowledge of eubacteria isolated from diverse coastal ecosystems of Goa, little explored for microbiological studies. These ecosystems need to be properly tapped in order to reveal potential bacteria yet to be exploited. The topics of this book are particularly relevant to researchers and students in the field of microbiology with an interest in the varied aspects of eubacteria. They provide academic insight for scientific communities in Goa and the rest of the world.

To cope with the increasing problems created by agrochemicals such as plant fertilizers, pesticides and other plant protection agents, biological alternatives have been developed over the past years. These include biopesticides, such as bacteria for the control of plant diseases, and biofertilizer to improve crop productivity and quality. Especially plant growth promoting rhizobacteria (PGPR) are as effective as pure chemicals in terms of plant growth enhancement and disease control, in addition to their ability to manage abiotic and other stresses in plants. The various facets of these groups of bacteria are treated in this Microbiology Monograph, with emphasis on their emergence in agriculture. Further topics are Bacillus species that excrete peptides and lipopeptides with antifungal, antibacterial and surfactant activity, plant-bacteria-environment interactions, mineral-nutrient exchange, nitrogen assimilation, biofilm formation and cold-tolerant microorganisms.

Two-component systems are signaling pathways that regulate many bacterial characteristics, such as virulence, pathogenicity, symbiosis, motility, nutrient uptake, secondary metabolite production, metabolic regulation, cell division, and many more. These systems regulate physiological processes in response to environmental or cellular parameters and enable adaptation to changing conditions. They are also potential targets for anti-microbial drug design. In recent years, significant advances have been made in the understanding of the role of two-component systems, and molecular studies have uncovered basic mechanisms of signaling. In this book, expert contributors from around the world present the current knowledge on two-component systems in bacteria and critically evaluate the vast amount of exciting new information that has been brought to light in recent years. The book covers various topics, including: the structure-function analysis of two-component systems * the sensing mechanisms * essential or atypical two-component systems and signaling networks * two-component systems in stress responses * two-component systems in developmental processes * two-component systems in virulence and symbiosis. The book provides a comprehensive overview for graduate students, academic scientists, and researchers in the pharmaceutical industry. This major reference work is essential reading for everyone working on bacterial regulation or anti-microbial drug design and is a recommended volume for all microbiology libraries.
