Abstract
At the world level, the seaweed industry is in constant progression, with a production (more than 8 million tons per year) which doubled since the 80s and a global turnover of approximately 7 billion US dollars. Brown seaweeds are the most common and widely cultivated.
Seaweeds offer prospects of applications in many industrial sectors: vegetables, food processing, in the form (hydrocolloids) for their thickening power (agar) or gelling (alginate, carrageenan), agriculture, soil improvers (calcareous seaweeds), chemical industry (biodiesel, plastic, molecules of pharmaceutical interest), cosmetics and medicine.
Our work has a double objective; on the one hand the chemical valorization of Cystoseira stricta by determining the rate of lipids and on the other hand, the bacteriological analyses of the two stations to know more about the environmental conditions of this species.
According to the obtained results, we can say that the studied alga has a more or less interesting value seen the rate of lipids quantified in the species living in the station of Stidia compared to that of the Sablettes. These results allowed us to confirm the richness of this kind of alga in organic substances.
Key words: Brown algae, Cystoseira stricta, lipids, bacteriological analyses.
