This book contributes research findings why the soda lakes become productive. Studying the nitrogen cycle in the soda lakes provides ideas about the activities of microbes and other aquatic life since nitrogen is vital for life. Ammonia oxidation is the rate limiting step in nitrogen cycle.This assures the significance of studying ammonia oxidation from other components of nitrogen cycle. Microbes were isolated from open water and mud of lake Arengude, Abijata, Shalla and Chitu. Then, the microbes were characterized to know their physiological reaction to high pH and salts. Therefore, the book is very important for microbiologists, liminoligists, and the one who study aquatic environment. In addition, it is also crucial to bio-technologists who are working on nitrogenous waste treatments.
