This book contains 10 chapters and each chapter carries topics related to Plant Growth Promoting Bacteria (PGPB). Chapter 1, mainly describes the basic information of the whole content of plant growth-promoting bacteria (PGPB). In chapter 2, the author has collected the sources of PGPB that available in the natural resources or those bacteria that were already cultivated in the laboratory. In addition, in chapter 3, the author had delineated in detail about the traits that were present in most of the PGPB. Furthermore, in chapter 4, the author has described in detail how the trait that was presented in those PGPB were used in the mechanism of PGPB when it is interconnected with the plants. The author also has shown various types of production systems that can be used to cultivate the natural plant growth-promoting bacteria in chapter 5. Through this system, more and wider application or delivery of PGPB that can be carried out in the natural environment is well described in the chapter 6. The author also defined numerous types of concerns that may arise from the application of PGPB and specific policy that closely related to PGPB in chapter 7 and 8, respectively. Prior to the chapter 10 which conclude the whole content, the author has listed out in chapter 9 the success of PGPB research. The author hope that all readers will gain detailed information about PGPB through reading and referencing this book.
