Development in Wastewater Treatment Research and Processes: Microbial Ecology, Diversity and Functions of Ammonia Oxidizing Bacteria covers up-to-date research on ammonia oxidizing bacteria and their application for the removal of ammonia nitrogen from wastewater treatment plants (WWTPs), discussing remaining gaps in their biology and functions. In this sense, this book features the application of the newly developed omics tools in order to develop less energy intensive and cost-effective biological processes for nitrogen removal from WWTPs. This makes this book an essential and unique book for advanced students, research scientists, environmental agencies and industries involved in wastewater treatment. - Covers the application of different omics tools for studying the microbial ecology, diversity and function of ammonia oxidizing bacteria in wastewater treatment plants (WWTPs) - Describes the role of ammonia oxidizing microorganisms in WWTPs - Presents the microbial ecology of ammonia oxidizing bacteria in WWTPs - Includes the microbial diversity of ammonia oxidizing bacteria - Emphasizes important aspects of cutting-edge molecular tools in the study of metabolic pathways of ammonia oxidizing bacteria
