Microbial Control: Bacterial Growth, Nitrification, and Bioremediation

This lecture covers topics related to microbial control, including bacterial growth phases, nitrification process in wastewater treatment, and bioremediation techniques using bioaugmentation. It discusses the factors affecting microbial efficiency, the sterilization methods involving heat and dry heat, and the importance of pasteurization. The instructor presents case studies on the application of specific bacteria for soil decontamination and the operation of a chemostat for biomass production. Various parameters such as cell concentration, growth rate, and substrate utilization are analyzed to determine the operational time of the reactor. Additionally, the lecture explores the significance of controlling water parameters in microbial processes and the different methods for microbial decontamination.
