The Purple Phototrophic Bacteria

About this book

The Purple Phototrophic Bacteria is a comprehensive survey of all aspects of these fascinating bacteria, the metabolically most versatile organisms on Earth. This book is a compilation of 48 authoritative chapters, written by leading experts who highlight the huge progress made in spectroscopic, structural and genetic studies of these bacteria since 1995, when the last book on this topic was published.

This new volume is similarly intended to be the definitive text on these bacteria for many years to come, and it will be a valuable resource for experienced researchers, doctoral & masters students, as well as advanced undergraduates in the fields of ecology, microbiology, biochemistry, biophysics, integrative biology, and molecular & cell biology. Scientists interested in future applications of these bacteria which could harness their potential for nanotechnology, solar energy research, bioremediation, or as cell factories, will also find this book useful.
