ABSTRACT: The biofuel production from marine algae is feasible but not yet economically viable compared to fossil fuel production. This work displays key reactions, processes and combination of innovative green chemistry in order to lead to a competitive biofuel production. The evaluation of chemical contents of two marine algae revealed that the major components of them are proteins, carbohydrates and lipids. To produce biofuel from marine algae with economically sustainable cost, each added value chemical content has to be valorized. This work demonstrates that each marine algae is unique and presents specific added value products specifically their secondary metabolites. Re isolation and reproducibility of specific metabolites from red alga, Portieria hornemannii and the cultured marine diatom, Phaeodactylum tricornutum were successful. Examples of formulation products from Portieria hornemannii and Phaeodactylum tricornutum are given to illustrate the feasibility of the process.
