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
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
The Streptomycetes are industrially widely used microorganisms due to their ability to produce numerous different chemical compounds. These show very varied effects upon other living systems, and result from profound and subtle biochemical and morphological differentiation during the streptomycete life cycle. It is therefore not surprising that research on the genetics of antibiotic biosynthesis and differentiation in this group is currently progressing rapidly in many countries. Intimately connected with the production of antibiotics is resistance to them; analysis of this is giving further information about the origin and evolution of this class of genes and their hypothesized spread among other microorganisms. Another interesting feature of the Streptomyces group is their mycelial growth. Also, their ecologically important utilization of high molecular weight compounds requires enzymes to be transported outside the cell to hydrolyze non-diffusible substrates. Finally, we have as yet limited understanding of the various mechanisms of genome rearrangement observed in some of these species; deletions and/or amplifications of enormous amounts of DNA can occur without seriously affecting the viability of the organism under laboratory conditions. The present volume, which includes contributions addressing the above subjects and others, originates from a meeting on "Genetics and Product Formation in Streptomyces" sponsored by the Federation of European Microbiological Societies in Erfurt on May 1-6 1990. Compared to previous ones of this kind held in 1979, 1983 and 1987 in Weimar, one can point to impressive progress in the study and applications of Streptomyces genetics.
