Explore the fascinating world of microbes with this comprehensive, advanced undergraduate-level textbook
Microbial Physiology: Unity and Diversity takes readers on a captivating journey through the intricate and often underappreciated world of microbial physiology, emphasizing both the common features that unify microbes and the diversity that makes them unique. In Part I: Unity, the book lays a strong foundation in the basics of microbial physiology. Delve into the three domains of life, get an intimate look at the metabolic pathways that fuel the microbial world, and take a deep dive into the cellular components that constitute a microbe. Further, explore the principles of cellular growth, bioenergetics, and the mechanics of respiration and fermentation. The Unity section concludes with a comprehensive discussion of regulation at posttranslational and gene levels, paving the way for a rich understanding of microbial function. Part II: Diversity, takes the reader into the broad and versatile world of microbial metabolism, exploring the range of energy sources and metabolic pathways microbes employ. This section leads readers through topics such as autotrophy, phototrophy, chemotrophy, and microbial contributions to the carbon, sulfur, and nitrogen cycles. The complexity of microbial cell envelope structures, transport processes, and protein transport are explored, along with bacterial motility, chemotaxis, and the phenomenon of quorum sensing. The section concludes with an exploration of stress responses and the diverse lifestyles that bacteria can adopt.
Microbial Physiology: Unity and Diversity will engage readers with its accessible yet thorough treatment of this critical field of microbiology. Each chapter contains detailed illustrations that concisely explain complex topics and concludes with robust end-of-chapter questions that not only test understanding but also provide an opportunity for readers to dig deeper into the content. This book is a must-have for students studying microbiology, as well as researchers and professionals keen to brush up their knowledge or explore new facets of microbial physiology.
