Resumo: | The search for renewable sources of biofuels is growing every day. As an example, we have biodiesel, a non-fossil fuel that can totally or partially replaces petroleum diesel without the need for adaptation. Microalgae can be used as raw material to produce biodiesel due to its growth rate and for having high lipid yields, in addition to its great capacity to develop in different environments. The use of microalgae to produce biofuels can be a potential and economical alternative in relation to other fuel sources. In addition to the high content of lipids and carbohydrates, they show rapid growth and high efficiency in fixing CO2. Thus, this work aimed to cultivate the microalgae Scenedesmus sp. in different regimes, analyzing the best conditions to produce bio-oil. The tests were carried out varying the culture medium, light, reactor, days of cultivation and aeration of the environment, totaling 16 tests. After carrying out the experiment was decided that the best microalgae cultivation regime aiming at a percentage of oil was using an inoculum of 20% of the useful volume in a horizontal reactor, with CHU culture medium and maximum light intensity with three “light” lamps how daylight, and duration of 30 days, with aeration and without vitamins addition. The associated effects of aeration, luminosity, cultivation time and growth medium, had a greater influence on the production of lipids. |

Como ejemplo tenemos el biodiésel, un combustible no fósil que puede sustituir total o parcialmente al diésel de petróleo sin necesidad de adaptación. Las microalgas pueden utilizarse como materia prima para la producción de biodiesel por su tasa de crecimiento y también por tener altos rendimientos de lípidos, además de su gran capacidad para desarrollarse en diferentes ambientes. El uso de microalgas para la producción de biocombustibles puede ser una alternativa potencial y económica en relación con otras fuentes de combustible. Además del alto contenido de lípidos y carbohidratos, muestran un rápido crecimiento y una alta eficiencia en la fijación de CO2. Así, este trabajo tuvo como objetivo cultivar la microalga Scenedesmus sp., En diferentes regímenes, analizando las mejores condiciones para la producción de bioaceite. Las pruebas se realizaron variando el medio de cultivo, luz, reactor, días de cultivo y aireación del ambiente, totalizando 16 pruebas. Luego de realizar el experimento, se determinó que el mejor régimen de cultivo de microalgas para porcentaje de aceite fue utilizar un inóculo del 20% del volumen útil en un reactor horizontal, con medio de cultivo CHU y máxima intensidad lumínica con tres lámparas “light” tipo el día, y duración de 30 días, con aireación y sin adición de vitaminas. Los efectos asociados de aireación, luminosidad, tiempo de cultivo y medio de cultivo, tuvieron una mayor influencia en la producción de lípidos.A busca por fontes renováveis de biocombustíveis vem crescendo a cada dia. Como exemplo temos o biodiesel, um combustível não fóssil que pode substituir total ou parcialmente o diesel de petróleo sem a necessidade de adaptação. Microalgas podem ser utilizadas como matéria prima para a produção de biodiesel devido à sua taxa de crescimento e também por possuir elevados rendimentos de lipídios, além de grande capacidade de desenvolver em diferentes ambientes. A utilização de microalgas para produção de biocombustíveis pode ser uma alternativa potencial e econômica em relação as outras fontes de combustíveis.

Desta forma este trabalho teve como objetivo cultivar a microalga Scenedesmus sp., em diferentes regimes analisando as melhores condições para produção de bio-óleo. Os ensaios foram realizados variando o meio de cultivo, luminosidade, reator, dias de cultivo e aeração do ambiente totalizando 16 ensaios. Após a realização do experimento definiu-se que o melhor regime de cultivo das microalgas visando porcentagem de óleo foi utilizando inoculo de 20% do volume útil em um reator horizontal, com meio de cultivo CHU e intensidade luminosa máxima com três lâmpadas do tipo “luz do dia”, e duração de 30 dias, com aeração e sem adição de vitaminas. Os efeitos associados da aeração, luminosidade, tempo de cultivo e meio de cultura, apresentaram maior influência na produção de lipídeos.Research, Society and Development2022-01-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2456510.33448/rsd-v11i1.24565Research, Society and Development; Vol. 11 No. 1; e18411124565Research, Society and Development; Vol. 11 Núm. 1; e18411124565Research, Society and Development; v. 11 n. 1; e184111245652525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/24565/21766Copyright (c) 2022 Witter Duarte Guerra; Flávia Costa Oliveira; Jaqueline Elise Garcia Chiesa; Isabela de Souza Dias; Andressa Tironi Vieira; Wesley da Silva Borges; Alexandre Sylvio Vieira da Costa; Anízio Marcio de Faria; Antônio Carlos Ferreira Batistahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessGuerra, Witter Duarte Oliveira, Flávia Costa Chiesa, Jaqueline Elise Garcia Dias, Isabela de Souza Tironi Vieira, Andressa Borges, Wesley da Silva Costa, Alexandre Sylvio Vieira da Faria, Anízio Marcio de Batista, Antônio Carlos Ferreira 2022-01-16T18:08:18Zoai:ojs.pkp.sfu.ca:article/24565Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:43:04.543532Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
