Have you ever thanked microbes for your nitrogen? Even though every living organism needs nitrogen, only some bacteria and archaea are capable of turning atmospheric nitrogen (N2) into the kind we can use (NH4+/NH3). Grab some markers and learn about how this process is done and regulated!
These videos are based on UC Berkeley's MCB/PMB C112 class (taught in Fall 2025 by Dr. Kathleen Ryan).
Chapters:
