Book Description
The Bacteria: Volume IX: Antibiotic-Producing Streptomyces explores how Streptomyces, including actinomycetes, produce a variety of antibiotics such as aminocyclitols, ansamycins, macrolides, and tetracyclines. Topics covered range from physiology and fermentation to genetic recombination and chromosome mapping in Streptomyces, biomodification of antibiotics by Streptomyces, and biosynthesis of tylosin and erythromycin. The genome structure and evolution of Streptomyces are also discussed. This volume is comprised of 10 chapters and begins with a discussion on the taxonomy of Streptomyces based on morphology, physiological characteristics, the composition of cell constituents such as cell walls, and the presence of characteristic lipids, sugars, and quinones. The discussion then turns to the intraspecific and interspecific recombination in Streptomyces; pathways of DNA repair and mutagenesis in Streptomyces fradiae; strategies for isolation of improved Streptomyces mutants for antibiotic production; and derivation of DNA cloning vectors from Streptomyces phages. The biology and use of Streptomyces plasmids as cloning vectors are also described. The final chapter is devoted to major structural classes of antibiotics produced by Streptomyces, including anthracyclines and other quinones, ß-lactams, macrolides, nucleosides, peptides, polyenes, polyether antibiotics, and tetracyclines. This book will be of value to microbiologists, bacteriologists, biochemists, and biologists.

Book Description
This book highlights the lives of a group of soil microbes that make most of the antibiotics used in medicine today. Written by an insider, it describes how genetics tells us how these microscopic chemists compete in the soil and how their genes can be rearranged to make new antibiotics to fight re-emerging diseases.

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
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.
