Structure of Some Bacterial Pigments (With Diagram)
Besides the photosynthetic bacteria, many other bacteria produce characteristic pigments. Biosynthesis of such non-photosynthetic pigments is genetically controlled and, therefore, pigmentation can be used as reliable taxonomic characters in identification. Some pigments are insoluble in aqueous media and they remain restricted to the cells, while others are soluble and they diffuse from the cells into the surrounding medium. Sometimes the [...]
