Production of Microbial Lipids from Wastewater

Human activities related to nitrogen have caused an overarching problem ‐ an imbalance in the global nitrogen cycle. Through conventional wastewater treatment processes, mainly a combination of aerobic nitrification and anoxic denitrification processes, ammonia and other forms of nitrogen can be converted into nitrogen gas and return back to the nitrogen cycle. However, this approach not only requires significant input of energy and oxygen but also produces greenhouse gas like nitrous oxides during denitrification. A novel way to reduce energy and oxygen inputs while minimizing greenhouse production for nitrogen removal is necessary.
