2. Nitrogenase is inactivated by oxygen, so the heterocyst must create a microanaerobic environment.
3. Certain heterocyst-forming bacteria can differentiate into spore-like cells called akinetes or motile cells called hormogonia, making them the most phenotyptically versatile of all prokaryotes.
4. The mechanism of controlling this nitrogen fixation pathway is thought to involve the diffusion of an inhibitor of differentiation called patS . Heterocyst formation is inhibited in the presence of a fixed nitrogen source, such as ammonium or nitrate.
