Codium bursa: Example of nutritional transfer between minerals and animals. Dissemination 105th
Classified by Carl Adolph Agardh (1817), it forms part of the group of chlorophytic and photophilous algae. It is attached to sea very deep or rocky bottoms between 3 and 40 m depth. It is formed by a hollow sphere filled with water, with internal filaments, which give it spherical shape. This shape and its high chlorophyll content (0.52 ug per mm2) give C.bursa a high efficiency in the absorption of sunlight.
Together with other chlorophytic algae, Codium bursa plays an important role in the transfer of ingredients between the minerals and the animals. Thus, only from solar energy, it is able to produce, by chlorophilic function, carbohydrates (10% of its weight) reducing the amount of CO2 of the sea water and consequently of the atmosphere. It produces protein (5% of its weight) and lipids (1% of its weight) for animal consumption, especially sea urchins and molluscs to which also it contributes important amount of minerals (30% of their alive weight) especially calcium (3% of Its weight) used for the formation of shells. Finally C.bursa contains 4 mg per gram of phenolic compounds with antibacterial and antifungal activity.
This is why C. bursa is an example of the importance of green algae in the food chain and the Shikimic acid route and is considered an edible seaweed in many cultures around the Atlantic and Mediterranean.
