Item Cultivo fototrófico, mixotrófico e heterotrófico de microalgas em esgoto doméstico visando a produção de biodiesel(2019-12-12) Marques, Isabela de Lima; Santos, Maria de Lourdes Florencio do; http://lattes.cnpq.br/9481193101590250; http://lattes.cnpq.br/7348426905838269Improvement of technologies in the cultivation of microalgae using domestic wastewater implies the reduction of the costs involved in the decontamination of the polluted waters by these effluents, as well as generating inputs for obtaining clean energy sources. The biodiesel production from microalgae has the main advantages: (i) not competing for arable land, (ii) not needing pesticides and excessive water consumption, and (iii) presenting high growth rates and high lipid biomass intracellular. Thus, the present research promoted the cultivation of microalgae D. subspicatus in domestic wastewater under different energy metabolism, in order to optimize growth rates, concentrations of cells in culture, and therefore, identify the crop conditions that promotes better intracellular lipid production, making biofuel production from microalgae, more economically and environmentally sustainable.Item Uso de metanálise para avaliação do potencial energético do uso da biomassa residual da extração da fibra de sisal(2022-05-26) Silva, Tássia Cristina da; Freitas, Ana Dolores Santiago de; http://lattes.cnpq.br/6734173724110965; http://lattes.cnpq.br/1670545246505006Agave, also called sisal, is a plant with origins in Mexico. In Brazil sisal is cultivated for the extraction of plant fiber; however, only 5% of the plant's weight is converted into fiber. The other 95% is converted into lignocellulosic residue. This residual biomass is not efficiently or economically utilized and is usually disposed of near the fiber extraction site. Considering this, the present work aimed to gather elements that can contribute to the sustainable development of the semi-arid region by providing information about the energy use of sisal residue. From the 48 papers analyzed it was possible to observe that sisal waste biomass possesses the characteristics of lignocellulosic biomass and that it is possible to convert this material through fermentation and pyrolysis into value-added products such as ethanol (biofuels) or biochar.
