ABSTRACT
Caulerpa racemosa, Enteromorpha intestinalis, Ulva Fasciata, U.lactuca, Halopteris scoparia, corallina mediterranea, hypnea musciformis and pterocladia capillacea are collected from two regions with different degree of pollution, Abu Qir and Eastern Harbour. Ash, inorganic and organic species of marine algae 1- Ashcontentreaching to 53.0 mg g[-1] for Ulva fasciata and 350.0 mg g[-1] for coralline mediterranea. 2- Inorganic carbon ranged between 110.0 and 451.0 mg.g[-1] for Enteromorpha intestinalis and coralline meditrranea respesctively. 3- Organic carbon content is degraded from 604.3 to 131.0 mg g[-1] for Caulerpa eacemosa and Corallina mediterranea. 4- Total carbohydrates vary from 36.0 and 92.0 mg g[-1] for Hypna musciformis and pterocladia capillacea, respectively. 5- Protein contents are more fluctuated from 68.0 to 343.0 mg g[-1] for coralline mediterranea and ulva fasciata, respectively. 6- the algal protein is characterized by high level of glutamic and aspartic acids, valine, leucine, arginine, lysine and phenylalanine
