The search for biofuels has been driven in recent decades due to concern over the depletion of non- renewable energetic sources. This literature review provides an approach to the application of microorganisms for the production of bioethanol, with emphasis on microalgae. The high efficiency of photosynthetic conversion, rapid growth, the possibility of manipulation of the medium to produce biomass with high fat and carbohydrates, and the use of areas with low agricultural potential of microalgae are one of the most promising raw materials for the production of biofuels. The existence of a large variety of methods for obtaining microalgal and subsequent production of bioethanol, biomass stimulated numerous studies to increase the production potential and improve the process. Studies show that for the production of bioethanol achieve economic viability, production of algal biomass should also aim at obtaining other compounds with higher added value, such as pigments, proteins, polyunsaturated fatty acids, according to the concept of integrated biorefineries.Downloads
