Plectonema boryanum, were voracious degraders of diflubenzuron (Table III). Just 5 mg of algae cells could metabolize almost 80% of the applied diflubenzuron in just 1 hr. Curiously, this pace was not sustained since 45 mg of algae could degrade only 95% of the applied dose after four days.

Nitrogenases are also extremely labile in an O2 environment. Cyanobacteria have adopted two strategies to overcome the O2 sensitivity of the nitrogenase reaction, either temporal or spatial separation of O2 evolution and H2 production. Temporal separation has been achieved mainly in non-heterocystous unicellular cyanobacteria such as Gloeothece sp. strain ATCC 27152 and Plectonema boryanum. Nitrogen fixation occurs only in darkness, during which respiration of the carbohydrates, syn...
