| Résumé : |
The diversity of life remains one of the most striking aspects of our blue planet. It is estimated that about 195,000 eukaryotes species are catalogued in oceans and more than 2,200,000 are predicted. These data include animalia, chromista, fungi, plantae and protozoa without any precise mention for microalgae and macroalgae.
Nowadays, algae are classified in four kingdoms: Cyanobacteria, plantae, chromista and protozoa. Among them, macroalgae constitutes an exceptional reservoir of innovative molecules for cosmetic purposes due to the important algal biodiversity throughout the world. They may bring numerous bioactive compounds incorporated in a wide range of products like creams, lotions and shampoos among others. |
