Microbes are vitally important to all life on Earth. As versatile organisms, they play a major role in various biochemical processes such as biodegradation, biodeterioration, climate change, food spoilage, epidemiology and biotechnology. The exponential rise in the quantity of scientific information and the rate at which new discoveries are made, require much elaborated, interdisciplinary and up-to date information and their understanding. The book Microbiology Concepts with Experiments for Agricultural and Food Microbiology has been written to serve as a guidebook for undergraduates and postgraduates of different universities. The chapters have been so arranged to give a sequential knowledge of the introductory basic agricultural microbiology, molecular biology, and plant metabolic pathways, elements of immunology, industrial microbiology, fermentation technology and principle working of basic equipments in this guide book.
