Visible Light-Driven Organic Synthesis covers the recent cutting-edge investigations in the field of visible light- driven organic synthesis in a single comprehensive volume. It provides information on rigorously selected reaction schemes and covers new reactions and new methods under visible light photocatalysis. It enlists more than 100 important synthetic strategies/methodologies with particular emphasis on useful reactions for organic synthesis under the mild reaction conditions reported in recent times involving carbon-carbon (C-C) and carbon-heteroatom bond-forming reactions, resulting in a wide spectrum of chemical compounds, providing an outstanding source of information concerning industrial applications. The chapters are classified based on various photocatalysts that have found direct applications in organic synthesis by carrying out different kinds of organic reactions. Each chapter is dedicated to a particular photocatalyst, and each selected reaction is dealt with in a compact manner through point-wise discussion under distinct subheadings covering the reaction type, reaction conditions, bond-forming information, reaction strategy involved, general reaction scheme, examples of representative entries with chemical structures and physical properties, a suggested plausible mechanism, critical views, and literature. In addition, visible light-mediated self-sensitized organic transformations that took place without any external photocatalysts have also been covered. This book is immensely helpful to chemistry students, teachers, researchers, academicians, and chemical/ agrochemical industry people to access the latest information and advances on visible light-driven organic synthesis developments.

Biotechnology of Microbial Enzymes: Production, Biocatalysis, and Industrial Applications, Second Edition provides a complete survey of the latest innovations on microbial enzymes, highlighting biotechnological advances in their production and purification along with information on successful applications as biocatalysts in several chemical and industrial processes under mild and green conditions. The application of recombinant DNA technology within industrial fermentation and the production of enzymes over the last three decades have produced a host of useful chemical and biochemical substances. The power of these technologies results in novel transformations, better enzymes, a wide variety of applications, and the unprecedented development of biocatalysts through the ongoing integration of molecular biology methodology, all of which is covered insightfully and in-depth within the book. This fully revised, second edition is updated to address the latest research developments and applications in the field, from microbial enzymes recently applied in drug discovery to penicillin biosynthetic enzymes and penicillin acylase, xylose reductase, and microbial enzymes used in antitubercular drug design. Across the chapters, the use of microbial enzymes in sustainable development and production processes is fully considered, with recent successes and ongoing challenges highlighted.
