Differential interference contrast (DIC) light micrograph of Spirulina sp. cyanobacteria filaments. Each filament is a colony of bacterial cells. Cyanobacteria are photosynthesizing bacteria that are found in most habitats where water is present. They are also used as a health food and dietary supplement because of their high protein content. Magnification: x550 when printed at 10 centimetres wide at its longest edge. | |
