Cyanobacteria are photosynthetic organisms and are the only prokaryotes known to have a circadian lifestyle. Unicellular diazotrophic cyanobacteria such as Cyanothece sp. ATCC 51142 produce oxygen and can also fix atmospheric nitrogen, a process exquisitely sensitive to oxygen. To accommodate such antagonistic processes, the intracellular environment of Cyanothece oscillates between aerobic and anaerobic conditions during a day-night cycle. This is accomplished by temporal separation of the two  ...[more]
