The book comprises a total of 16 chapters from multiple contributors around the world, in‐ cluding Brazil, South Africa, Saudi Arabia, Colombia, India, China, Mexico, and the United States. We are grateful to all the contributors and leading experts for the submission of their stimulating and inclusive chapters in the preparation of the edited volume to bring the book on Actinobacteria basics and biotechnological applications. We offer our special thanks and appreciation to Ms. Ana Pantar and Ms. Sandra Bakic, Publishing Process Manager, for their

We express our heartfelt gratitude to Prof. Cheng-Lin Jiang, Key Laboratory for Microbial Resources of Ministry of Education, Yunnan Institute of Microbiology, Yunnan University, Kunming, Yunnan 650091, P.R. China, for his valuable conceptual suggestions and proof comments during the review process of this book. Appreciations are due to my research scholars, Ms. S. Latha, Ms A. Ranjani, and Ms. G. Vinothini, for their sincere efforts and dili‐ gence toward this book. We are also indebted to InTech-Open Science, Bharathidasan Uni‐ versity, and Yunnan University for their concern, efforts, and support in the task of

Actinobacteria hold a prominent position as targets in screening programs due to versity and their proven ability to produce novel metabolites. They are nowned as secondary metabolite producers and hence are of high pharmacological commercial interest. Approximately, 23,000 microbial secondary metabolites dous economic importance have been identified so far, in which 12,000 compounds duced by Actinobacteria. Interestingly, 7600 bioactive compounds are reported from members of the genus Streptomyces with antibacterial, antifungal, antiviral, antihelminthic, antialgal, antimalarial, anticancer, anti-inflammatory, antithrombotic, X Preface

Actinobacteria hold a prominent position as targets in screening programs due to their di‐ versity and their proven ability to produce novel metabolites. They are universally re‐ nowned as secondary metabolite producers and hence are of high pharmacological and commercial interest. Approximately, 23,000 microbial secondary metabolites with tremen‐ dous economic importance have been identified so far, in which 12,000 compounds are pro‐ duced by Actinobacteria. Interestingly, 7600 bioactive compounds are reported from the members of the genus Streptomyces with antibacterial, antifungal, antiviral, antiprotozoan, antihelminthic, antialgal, antimalarial, anticancer, anti-inflammatory, antithrombotic, and
