Abstract
In a young culture, photosynthetic-oxygen evolution by Gloeocapsa is at a low level while nitrogenase activity is at its greatest. When the culture ages, there is a rapid increase in photosynthetic pigments and oxygen evolution, and nitrogenase activity decreases. The temporal separation of nitrogen fixation and photosynthesis may serve to protect nitrogenase from oxygen denaturation.
