Seaweeds have considerable economic interest, they may be classified among the most important marine substances. They are important in most industries, especially in the pharmaceutical, food and environmental. Algae we targeted are brown algae of the family Cystoseiracées. Indeed, several previous scientific research on this kind have shown their remarkable potential for pharmaceutical scale and as adsorbents of heavymetals. In this work we analyzed the texture for Cystoseira tamariscifolia and Bifurcaria bifurcata by scanning electronmicroscopy coupled with energy dispersive analysis of X-ray Spectroscopy (SEM / EDAX) spectroscopy and Fourier Transform Infrared (FTIR). The the results obtained by scanning electron microscopy show firstly, very irregular and porous structures, and a heterogeneity of the pores on all surfaces and Cystoseira tamariscifolia Bifurcaria bifurcata. On the other hand, analysis by microanalyses Energy Dispersive X-ray Spectroscopy showed the presence of a significant organic composition with respect to the minerals. These results were confirmed by infrared spectroscopy Fourier Transform.
