Cyanobacteria appear to separate these two processes with their plasma membrane containing only components of the respiratory chain, while the thylakoid membrane hosts an interlinked respiratory and photosynthetic electron transport chain.

Cyanobacteria fulfill vital ecological functions in the world's oceans, being important contributors to global carbon and nitrogen budgets.

FactSnippet No. 1,096,526

Cyanobacteria can enter the plant through the stomata and colonize the intercellular space, forming loops and intracellular coils.

FactSnippet No. 1,096,527

Cyanobacteria are able to produce sulphated polysaccharides that enable them to form floating aggregates.

FactSnippet No. 1,096,528

Cyanobacteria remained principal primary producers throughout the Proterozoic Eon, in part because the redox structure of the oceans favored photoautotrophs capable of nitrogen fixation.

FactSnippet No. 1,096,529

Cyanobacteria remain critical to marine ecosystems as primary producers in oceanic gyres, as agents of biological nitrogen fixation, and, in modified form, as the plastids of marine eukaryotic algae.

Cyanobacteria are challenged by environmental stresses and internally generated reactive oxygen species that cause DNA damage.

FactSnippet No. 1,096,531

Cyanobacteria were traditionally classified by morphology into five sections, referred to by the numerals I–V.

FactSnippet No. 1,096,532

Cyanobacteria have been engineered to produce ethanol and experiments have shown that when one or two CBB genes are being over expressed, the yield can be even higher.
