The fundamental concern of this subject is to understand the characteristics of complex organisms by studying single-celled organisms. Microorganisms are vital in many environmental and industrial processes such as digestion, bioremediation, decomposition, fermentation, etc. This book explores all the important aspects of microbial physiology in the present day scenario. Those in search of information to further their knowledge will be greatly assisted by this book.
