The book titled MICROBES An Invisible Universe by Howard Gest was one of the most informative and interesting books I have read on the world of microbes. This book is 200 pages crammed full of detailed information about the history and the function of microorganisms, also known as microbes. The author, Dr. Howard Gest is Distinguished Professor Emeritus of Microbiology and Adjunct Professor of History and Philosophy of Science at Indiana University, Bloomington. Dr. Gest is widely recognized for his research on microbial physiology and metabolism.
The Ecology of microbes to one another and their surroundings is extraordinary with respect to the diversity of chemical and physical conditions that can be tolerated. Microbes thrive in extreme environments with regards to temperatures, high concentrations of salts and sugars, relative acidity, and with or without the presence of oxygen.
