ABSTRACT
Algal cultures can be used to produce several products as vitamins, feed, biofuels, and other products on industrial scale. The growth in world energy demand has led to the development and analysis of efficient sources capable of producing fuels and chemicals. Thus, microalgae are seen as a promising alternative for the production of fuels and chemicals due to their high photosynthetic conversion efficiency. There are several processes to produce alternative energy by algal. Between them, we have biochemical conversion, thermochemical conversion, chemical reactions, 262and direct combustion; also, there is other alternative way to carry out the biomass treatments to produce high value chemicals as bioethanol. This chapter aimed to show some of the main technologies involved in algal transformation for commercial interests. Moreover, it is very important to study algal composition and apply the best technology to obtain the specific product of interest from this rich and potential feedstock.
