Avaliação do uso de biomassa de microalga como substrato para leveduras na síntese de etanol

Abstract

Currently, a change is being sought in the use of renewable sources for energy generation, to the detriment of the use of fossil fuels. This change is indispensable in a world economy scenario based on the concept of sustainable development. The existing variability of so many materials for the production of ethanol offers advantages for the production of energy, however, must choose those that have plausible characteristics. In this context, it is observed that microalgae have adequate characteristics for the production of fuel, depending on the type of treatment they are subjected to, the species under analysis and the biochemical composition of the biomass. Therefore, considering this constant search for more viable methods of pre-treatment of biomass, hydrolysis and fermentation, the present work seeks to address effective methodologies in the area of quality and yield of bioethanol, reinforcing the interest in the development of biofuels made from microalgae biomass.
