Resumo: | The production of biofuels through microalgae biomass represents a new generation of raw materials from renewable sources to meet society’s clamors and growing insertion in the market of fuels from products that could grant the planet a sustainable future. The present study assesses the biomass obtained from microalgae Chlorella vulgaris when grown in urban wastewater, extracting the lipids from the biomass and performing Gas Chromatography analysis of fatty acid methyl esters (FAME) composition after submitting the lipids through the transesterification process. The microalgae cultivation was monitored through chlorophyll (a) analysis and the highest cell growth was 845.8 µg L-1 using urban wastewater as growth medium. The nutrients of interest were monitored for primary concentration of 8.06 ± 0.06 mg L-1 of ammoniacal nitrogen, 12.27 ± 0.27 mg L-1 of nitrate and 21.22 ± 0.85 mg L-1 of phosphate, reducing about 99% of ammoniacal nitrogen and nitrate, along with reducing 87% of phosphate. The lipid constitution extracted from 3.7 g of dry biomass of Chlorella vulgaris after cultivation using urban wastewater, was 7.7%. The lipids extracted from the Chlorella vulgaris biomass are suitable biodiesel production regarding the amounts of FAMEs identified, after the analysis carried out, the comparison of the results obtained with other studies and the hypotheses evaluation. |

El presente estudio evalúa la biomasa obtenida de las microalgas Chlorella vulgaris cuando se cultiva en aguas residuales urbanas, extrayendo los lípidos de la biomasa y realizando un análisis de cromatografía de gases de la composición de Ésteres Metílicos de Ácidos Grasos (EMAG) después de enviar los lípidos a través del proceso de transesterificación. El cultivo de microalgas se controló mediante análisis de clorofila (a) y el mayor crecimiento celular fue de 845.8 µg L-1 usando aguas residuales urbanas como medio de crecimiento. Los nutrientes de interés se monitorearon para determinar la concentración primaria de 8.06 ± 0.06 mg L-1 de nitrógeno amoniacal, 12.27 ± 0.27 mg L-1 de nitrato y 21.22 ± 0.85 mg L-1 de fosfato, reduciendo aproximadamente el 99% de nitrógeno y nitrato amoniacal, junto con la reducción del 87% de fosfato. La constitución lipídica extraída de 3,7 g de biomasa seca de Chlorella vulgaris después del cultivo con aguas residuales urbanas, fue del 7,7%. Los lípidos extraídos de la biomasa de Chlorella vulgaris son una producción adecuada de biodiesel con respecto a las cantidades de EMAG identificadas, después del análisis realizado, la comparación de los resultados obtenidos con otros estudios y la evaluación de hipótesis.A produção de biocombustíveis através da biomassa de microalgas representa uma nova geração de matérias-primas a partir de fontes renováveis para atender as necessidades da sociedade e a crescente inserção no mercado de combustíveis de produtos que possam conceder ao planeta um futuro sustentável. O presente estudo avalia a biomassa obtida da microalga Chlorella vulgaris quando cultivada em águas residuais urbanas, extraindo os lipídios da biomassa e realizando a análise por cromatografia em fase gasosa da composição dos Ésteres Metílicos de Ácido Graxo (EMAG) após a submissão dos lipídios pelo processo de transesterificação. O cultivo de microalgas foi monitorado através da análise de clorofila (a) e o maior crescimento celular foi de 845,8 µg L-1, utilizando águas residuais urbanas como meio de crescimento. Os nutrientes de interesse foram monitorados quanto à concentração primária de 8,06 ± 0,06 mg L-1 de nitrogênio amoniacal, 12,27 ± 0,27 mg L-1 de nitrato e 21,22 ± 0,85 mg L-1 de fosfato, reduzindo cerca de 99% do nitrogênio e nitrato amoniacal, juntamente com a redução de 87% de fosfato. A constituição lipídica extraída de 3,7 g de biomassa seca de Chlorella vulgaris após o cultivo em águas residuais urbanas foi de 7,7%. Os lipídios extraídos da biomassa de Chlorella vulgaris são adequados para a produção de biodiesel em relação às quantidades de EMAG identificados, após a análise realizada juntamente com a comparação dos resultados obtidos com outros estudos e a avaliação de hipóteses.Research, Society and Development2020-06-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/488210.33448/rsd-v9i7.4882Research, Society and Development; Vol. 9 No. 7; e823974882Research, Society and Development; Vol. 9 Núm. 7; e823974882Research, Society and Development; v. 9 n. 7; e8239748822525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/4882/4248Copyright (c) 2020 Adna Caroline Vale Oliveira, Natália Ribeiro Melo, Isadora Machado Marques, Ícaro Thiago Andrade Moreirainfo:eu-repo/semantics/openAccessMarques, Isadora MachadoMelo, Natália RibeiroOliveira, Adna Caroline ValeMoreira, Ícaro Thiago Andrade2020-08-20T18:05:03Zoai:ojs.pkp.sfu.ca:article/4882Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:28:35.491002Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
