Abstract
Microalgae biomass is recognized as one of the most promising alternative sources for biofuels production, in addition to the capacity to absorb nutrients like nitrate and phosphate during cultivation, coupled with the treatment capacity of agro-industrial wastewater. The objective of this work is to contribute to the development of a microalgae biorefinery unit, through the increase of the productivity of microalgal biomass in cultures in a tubular photobioreactor with swine effluents to produce biofuels, in addition to the use of the cultures as a tool for the biological treatment of this effluent. The cultures will be carried out in a 10 L tubular photobioreactor, using the microalgae of the species Tetradesmus obliquus. Swine effluent from biodigester will be used as an alternative culture medium. The effluent bioremediation capacity and organic load reduction will be evaluated through determinations in the composition of the medium at the beginning and at the end of the cultures. The microalgal biomass composition will be evaluated to determine the potential of the species for biodiesel production. It is expected that the complex composition of the alternative culture medium and greater availability of nutrients present in the effluent will result in greater growth of microalgae, in addition to increasing the lipid content in the biomass resulting in greater productivity and potential as a raw material for biodiesel production, when compared to cultures with the synthetic medium. The present study aims to contribute to the development of a microalgae biorefinery unit, combining the increase in the productivity of biomass and lipids to produce biofuels, combined with the treatment of effluents.
