Microbial ecology studies the interactions between microorganisms and their environment, including the vital role they play in nutrient cycling. Within this field, the nitrogen cycle stands out as a critical process. Nitrogen, an essential element for life, undergoes transformations mediated by various microbes. Key stages include nitrogen fixation by nitrogen-fixing bacteria, which convert atmospheric nitrogen into forms usable by plants. This is followed by ammonification, where organic nitrogen from decaying matter is converted into ammonia by bacteria and fungi. Subsequent steps are nitrification, where ammonia is oxidized into nitrites and nitrates by nitrifying bacteria; and denitrification where certain bacteria convert nitrates back into atmospheric nitrogen. These microbial processes are fundamental for maintaining soil fertility, plant growth, and ecosystem balance. This book attempts to understand the discipline of microbial ecology and nitrogen cycle in an integrated manner. The various studies that are constantly contributing towards advancing technologies and evolution of this field are examined in detail. For all those who are interested in these subjects, this book can prove to be an essential guide.
