Algae are rich in proteins, carbohydrates, lipids, minerals, and vitamins. They are currently used intensively as food, food additives, pharmaceuticals, feeds, fertilizers, and cosmetics on a commercial scale. Algal polysaccharides are exclusive products due to their functional properties as dietary fibers and gelling agents. Nowadays, algae are attracting attention as a new and promising third-generation biofuel feedstock. They may be used to produce several kinds of biofuel, including biodiesel, bio-oil, biogas, bioethanol, bio-coal, and biohydrogen. However, biofuel production depends on the chemical composition of algae, which is affected by many factors. Besides being collected from nature, they are also cultured to enrich biochemical composition via aquaculture techniques. This chapter evaluates the biochemical compounds of micro- and macroalgae and the influence of cultivation conditions on those compounds and biofuel production.
