Resumo: | The microalgae can be used to capture and utilize CO2 emitted by thermoelectric power plants or other sources. Mitigation of emissions of greenhouse effect gases results from converting biomass harvested from microalgae into renewable energy source such as biodiesel, bioethanol, biogas and other substitutes for fossil fuels. The microalgae are usually cultivated in large tanks with agitation produced by rotating blades or technically projected photobioreactors. Algae multiply suspended in water when supplied with the necessary nutrients and the multiplication rate increases on supply of additional CO2. Compared to other biological options to capture and use CO2, microalgae cultivation has advantages of high productivity potential, ability to capture nutrients from wastewater, waste utilization, sources of salt water and high efficiency in water use. Microalgae are an attractive alternative to oilseeds such as soybeans and palms, because of high lipid content leading to higher oil output per hectare. The microalgae can be cultivated in industrial areas, require much less space and low soil fertility. This review aims to present some updates about the potential of cultivating microalgae for biofuel production. |

A mitigação das emissões dos gases do efeito estufa (GEE) resulta da conversão da biomassa colhida das microalgas em biocombustíveis renováveis, tais como o biodiesel, bioetanol, biogás e outros produtos de substituição dos combustíveis fósseis. As microalgas são usualmente cultivadas em grandes tanques com agitação promovida por pás rotativas ou em equipamentos tecnicamente projetados, os fotobiorreatores. Seu crescimento ocorre em suspensão na água quando são fornecidos todos os nutrientes necessários e, numa velocidade maior, quando há o fornecimento adequado de CO2. Comparadas a outras opções biológicas para a captura e a utilização do CO2, as culturas de microalgas têm como principais vantagens: potencial para alta produtividade, habilidade para capturar nutrientes das águas residuárias, das fontes de água salgada, alem de ter elevada eficiência no uso da água. As microalgas são uma atrativa alternativa às oleaginosas como soja, e palmáceas. Isso por causa da sua elevada densidade de lipídios, convertendo em maior produtividade de óleo por hectare. As microalgas podem ser cultivadas em uma instalação industrial, requerendo área muito menor, não exigindo fertilidade de solo. Diante do exposto, esta revisão tem por objetivo apresentar algumas atualizações sobre o potencial do cultivo de microalgas para a produção dos biocombustíveis.Universidade Federal de Viçosa - UFV2012-11-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/29210.13083/reveng.v20i5.323Engineering in Agriculture; Vol. 20 No. 5 (2012); 389-403Revista Engenharia na Agricultura - REVENG; v. 20 n. 5 (2012); 389-4032175-68131414-398410.13083/reveng.v20i5reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/292/220lira, rafael araujoMartins, Marcio ArêdesMachado, Mariana FonsecaCorrêdo, Lucas de Paulade Matos, Antonio Teixeirainfo:eu-repo/semantics/openAccess2023-01-19T13:03:49Zoai:ojs.periodicos.ufv.br:article/292Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T13:03:49Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false |
