Book Description
This is an insiders account of 50 years of genetic studies of the soil-inhabiting microbes that produce most of the antibiotics used to treat infections, as well as anti-cancer, anti-parasitic and immunosuppressant drugs. The book begins by describing how these microbes the actinomycetes were discovered in the latter part of the nineteenth century, but remained a Cinderella group until, in the 1940s, they shot to prominence with the discovery of streptomycin, the first effective treatment for tuberculosis and only the second antibiotic, after penicillin, to become a medical marvel. There followed a massive effort over several decades to find further treatments for infectious diseases and cancer, tempered by the rise of antibiotic resistance consequent on antibiotic misuse and over-use. The book goes on to describe the discovery of gene exchange in the actinomycetes in the context of the rise of microbial genetics in the mid-20th century, leading to determination of the complete DNA sequence of a model member of the group at the turn of the millennium. There follow chapters in which the intricate molecular machinery that adapts the organisms metabolism and development to life in the soil, including antibiotic production, is illuminated by the DNA blueprint. Then come an up-to-the minute account of the use of genetic engineering to make novel, hybrid, antibiotics, and a topical description of techniques to learn the roles of the thousands of genes in a genome sequence, throwing a powerful light on the biology of the organisms and their harnessing for increasing antibiotic productivity. In the final chapter we return to the mycobacteria that cause tuberculosis and leprosy, the first actinomycetes to be discovered, and how methodology, in part derived from the study of the streptomycetes, is being applied to understand and control these still deadly pathogens.

Book Description
This book presents an introductory overview of Actinobacteria with three main divisions: taxonomic principles, bioprospecting, and agriculture and industrial utility, which covers isolation, cultivation methods, and identification of Actinobacteria and production and biotechnological potential of antibacterial compounds and enzymes from Actinobacteria. Moreover, this book also provides a comprehensive account on plant growth-promoting (PGP) and pollutant degrading ability of Actinobacteria and the exploitation of Actinobacteria as ecofriendly nanofactories for biosynthesis of nanoparticles, such as gold and silver. This book will be beneficial for the graduate students, teachers, researchers, biotechnologists, and other professionals, who are interested to fortify and expand their knowledge about Actinobacteria in the field of Microbiology, Biotechnology, Biomedical Science, Plant Science, Agriculture, Plant pathology, Environmental Science, etc.

Book Description
Beyond being the most important natural compound source, actinomycetes are the origin of up to two-thirds of all clinically used antibiotics. Currently, new antimicrobials are urgently needed, as infections caused by antibiotic-resistant pathogens are on the rise. In the identification of new antibiotics, many scientists are currently investigating biosynthetic aspects of antibiotic production in actinomycetes. Since the emergence of next-generation sequencing technologies, the field of antibiotics research has experienced a remarkable revival. These bacteria have the potential to produce more antibiotics than previously thought possible. Some antibiotics are produced in standard media, while others require the presence of a specific signaling molecule in the medium. Others, however, are only produced when the native regulation of the biosynthesis gene cluster is overruled. This book covers topics in the field of antibiotic-producing actinomycetes. The following tops are addressed: - Approaches to access novel antibiotic producers for novel natural compounds - Omics and genome mining approaches for the discovery of novel natural compounds - Analyses and genetic engineering of antibiotic biosynthesis - Regulation of the secondary metabolism in actinomycetes

Book Description
Chemistry and Biology of ?-Lactam Antibiotics, Volume 1: Penicillins and Cephalosporins provides information pertinent to the study of antibiotics containing the ?-lactam moiety. This book discusses the occurrence of a group of ?-lactam antibiotics structurally related to cephalosporin C. Organized into five chapters, this volume begins with an overview of the mechanism of action of ?-lactam antibiotics that caused many microbiologists to develop screening tools for the detection of the ?-lactam moiety. This text then discusses the discovery of the nocardicins, the thienamycins, and olivanic acids. Other chapters provide a summary of the essential penicillin sulfoxide chemistry that gave rise to many compounds. This book discusses as well the ability of chemists to predict the level of biological activity of a compound from knowledge of its structure through theoretical and physicochemical studies. The final chapter deals with quantitative structure–activity relationships. This book is a valuable resource for microbiologists, chemists, and scientists.

Book Description
Biologically active compounds isolated from microorganisms continue to be vital to the development of new drugs and agricultural chemicals. This book was prepared by current and past members of the laboratory of Dr. Satoshi Omura of the Kitasato Institute in Japan. Dr. Omura and his colleagues have discovered and studied a number of important antibiotics, and in their work they have pioneered new methods for screening microbes for interesting and important compounds. This book presents strategies and methods for identifying novel molecules with several types of biological activity. In addition, the book discusses the identification of microbial compounds of agrochemical importance, presents information on chemical screening methods, and concludes with chapters on microbial strain selection, fermentation technology, and genetic engineering of antibiotic-producing microorganisms. This book will be of great interest to scientists working in the very active and competitive fields of antibiotic and agrochemical discovery.
