Modern approaches to microbial classification and identification, particularly those based on nucleic acid analysis, have raised the awareness and interest of microbiologists in systematics during the past decade. The extended scope of the subject has revolutionized microbial ecology with the demonstration of uncultivable microorganisms as a major component of the biosphere and evolution, with the ribosomal RNA phylogenetic tree as the basis of current classifications. However, advances in microbial systematics have also had enormous impact on other, diverse aspects of microbiology such as animal pathogenicity, plant-microbe interactions and relationships with food. In this book, we survey and discuss in depth the contribution of modern taxonomic approaches to our understanding of the microbiology of these various systems. The book does not concentrate on methods - these have been well reported elsewhere - instead it provides a unique insight into the application and value of modern systematics in diverse branches of microbiology. It will be of value to microbiologists at both research and technical levels who need to appreciate the range of organisms with which they work and the diversity within them. It will also be of value to teachers and students of microbiology courses who want to understand how systematics can enhance microbiology beyond the routine of classification, nomenclature, and identification.

Current chemosystematics owes much to the availability of highly sensitive analytical techniques. Many of these involve a quantitative approach, utilising computers and a variety of statistical techniques. This book contains up-to-date procedures on chemical methods being developed and used for the classification and identification of bacteria, including medically and economically significant ones. Detailed protocols are given on how valuable taxonomic data can be derived from analyses of nucleic acids, proteins, lipids and whole-organisms. Of general interest to microbiologists, the volume should also be an essential reference to those actively engaged in diagnostic bacteriology or microbial systematics. FROM THE PREFACE: Chemical methods not only are well established in bacterial systematics but are also rapidly changing our views on how bacteria should be classified and identified. Chemotaxonomy, which owes much to the availability of new and highly sensitive analytical techniques, can be used to establish relationships between bacteria at all levels in the taxonomic hierarchy. However, many of the new approaches are designed for the identification of bacteria and some are quantitative, employing computers and a variety of statistical techniques. This book contains detailed procedures on many of the chemical methods currently being used for the classification and identification of bacteria. As such, it will be of value generally to microbiologists and is an essential reference for those actively engaged in diagnostic bacteriology.

Methods in microbial systematics have developed and changed significantly in the last 40 years. This has resulted in considerable change in both the defining microbial species and the methods required to make reliable identifications. Developments in information technology have enabled ready access to vast amounts of new and historic data online. Establishing both the relevance, and the most appropriate use, of this data is now a major consideration when undertaking identifications and systematic research. This book provides some insights into how current methods and resources are being used in microbial systematics, together with some thoughts and suggestions as to how both methodologies and concepts may develop in the future.

This book presents recent scientific investigations in microbial ecology and systematics. Advanced microbial science investigations employ the latest technologies for research in microbiology and microbial applications. The book has complete information on classical microbiology techniques for assessment of the composition of microbial diversity assessment, advancement in next-generation technology, advantages of microbial products in sustainable developments and their application for societal benefits. Current research on microorganisms is presented as a perfect book for studies on "Microbial Systematics". This book will serve as an important resource for practising research and review for the scientific community.

This book provides microbiologists with a comprehensive treatment of concepts, ideas, and methods that make up the subject of modern bacterial systematics. It includes not only traditional numerical and chemotaxonomic methods, but also full coverage of molecular systematics. The book is divided into three sections - classification, nomenclature, and identification. The authors are world leaders in the field and many are involved in the "Bergey's manual," which is the bible of the field.

Inspired by the pace of change in the taxonomy of the aerobic endospore-forming bacteria, the "Bacillus 2000" symposium on which this book is based was held in Bruges, Belgium, in August 2000, and was supported by the Federation of European Microbiological Societies, the Belgian Society for Microbiology, and several commercial sponsors. Bringing taxonomists interested in Bacillus and its relatives together with people who work with these organisms in medicine, agriculture, and industry, allowed those attending to appreciate the overlaps and interactions of their areas of expertise, in the absence of any comprehensive treatment of the current systematics of the group. The meeting was a great success, and has resulted in the production of these proceedings, Applications and Systematics of Bacillus and Relatives, providing an up-to-date and comprehensive treatise on the classification, identification and applications of the aerobic endospore-forming bacteria; it is an essential reference for all microbiologists interested in these organisms. Valuable reference work for all those interested in the systematics of Bacillus and its relatives. Produced in response to the successful Bacillus 2000 meeting in Bruges and was supported by the Federation of European Microbiological Societies, the Belgian Society for Microbiology, and several commercial sponsors. Of use to those working in fields as diverse as medicine, agriculture, food and industry. Comprehensive and up-to-date analysis of the systematics of these organisms. Includes the application of sophisticated chemotaxonomic and genetic characterization methods.

The great diversity of microbial life is the remaining major reservoir of unknown biological diversity on earth. To understand this vast, but largely unperceived diversity with its untapped genetic, enzymatic and industrial potential, microbial systematics is undergoing a revolutionary change in its approach to describe novel taxa based on genomic/envirogenomic information. The characterization of an organism is no longer bounded by methodological barriers, and it is now possible to fully sequence the whole genome of a strain to study individual genes, or to examine the genetic information by using different techniques. In fact, application of genomics is helping not only to provide a better understanding of the boundaries of genera and higher levels of classification, but also to refine our definition of the species concept. In addition, increased understanding of phylogeny is allowing to predict the genetic potential of microorganisms for biotechnological applications and adaptation to environmental changes. The present Research Topic on “Microbial Taxonomy, Phylogeny and Biodiversity” compiles a collection of papers covering the use of genomic sequence data in microbial taxonomy and systematics, including evolutionary relatedness of microorganisms; application of comparative genomics in systematic studies; or metagenomic approaches for biodiversity studies. We hope that this eBook incentives and encourages researchers for future discussions on microbial taxonomy and phylogenetics.

Systematic biology has a far wider application than merely the provision of a reliable classification scheme for new strains. With the framework of the hierarchic system stabilizing, genomes, noncoding regions, and genes and their products can now be evaluated in an evolutionary context. This book summarizes recent developments in the molecular characterization of cultured and as-yet uncultured prokaryotes, emphasizing the strengths and weaknesses of individual approaches. The chapters of the book are compiled to stimulate students to enter the field of bacterial diversity, presenting a broad spectrum of fascinating multifaceted disciplines that illuminate the paths to ecosystem functioning, communication within communities, symbiosis, life in extreme environments, astrobiology, and more.
