DefinitionThis section has been translated automatically.

The purple red algae (Porphyridium cruentum) is a unicellular, purple-colored microalgae. It protects itself against moisture loss, salt stress and UV radiation by producing a mucus-like gel capsule. Prophyridium cruentum is used industrially, pharmaceutically and cosmetically.

General informationThis section has been translated automatically.

Porphyridium cruentum forms black-red to carmine-red, to plate-sized and membrane-mucilaginous jelly deposits. The individual cells are 7 to 12 micrometers in size, spherical to polygonal and brown-red to red. They form carbohydrates (florid starch). The chloroplasts are stained red by carotenoids.

Note(s)This section has been translated automatically.

Extracts from the purple micro algae are used in so-called algae cosmetics because of their skin-protecting properties.
