Resumo: | Air pollution is intensified by potentially polluting anthropogenic activities and impacts various sectors of society such as public health, the economy and the environment. From this, pollution treatment techniques are applied, however, they present some limitations, which results in the need to improve and develop new strategies. The aim of this research was to explore the biotechnological applications of microalgae and the integration in the processes of cultivation and production of bioproducts, as well as to evaluate the biotechnological potential of three species of microalgae for the biofixation of greenhouse gases (GHGs) in different concentrations. Therefore, two chapters are presented: 1) chapter 1 presents a discussion about atmospheric treatment techniques, addressing the problems of air pollution, applied physical, chemical and biological treatment techniques, their main challenges and opportunities that can be exploited on the basis of biotechnology, for the production of bioproducts; 2) chapter 2 presents the technical paper on tolerance evaluation of three species of microalgae (Chlorella vulgaris, Haematococcus pluvialis and Scenedesmus subspicatus) cultivated under four different concentrations of CO2 and NOx simultaneously, to GHGs biofixation and biomass reuse. From a theoretical context, it was possible to identify the main gaps related to the use of microalgae for the biofixation of GHGs and the need to expand biotechnological research aimed at the improvement and / or development of bioprocesses for the environmental treatment and obtaining of several products with high added value. Furthermore, it is necessary to explore the biological responses of cultivated species in nutrient recycling processes. In relation to microalgae species appraised, Chlorella vulgaris, Haematococcus pluvialis and Scenedesmus subspicatus showed tolerance to different concentrations of CO2 and NOx. The presented growth up was to 26% higher in the treatments with gas injection containing CO2 and NOx, which corroborates the hypothesis that they have potential for the GHGs biofixation. |

A partir disso, técnicas de tratamento da poluição são aplicadas, contudo, elas apresentam algumas limitações, o que resulta na necessidade de aprimoramento e desenvolvimento de novas estratégias. Pelo exposto, esta pesquisa objetiva explorar as aplicações biotecnológicas das microalgas e a integração nos processos de cultivo e obtenção de bioprodutos, além de avaliar o potencial biotecnológico de três espécies de microalgas para a biofixação de gases de efeito estufa (GEEs) em diferentes concentrações. Para tanto, são apresentados dois capítulos: 1) o capítulo 1 apresenta uma discussão a respeito das técnicas de tratamento atmosférico, abordando a problemática da poluição do ar, técnicas de tratamento físicas, químicas e biológicas aplicadas, seus principais desafios e oportunidades que podem ser exploradas com base na biotecnologia, no que se refere na obtenção de bioprodutos; 2) o capítulo 2 apresenta o artigo técnico sobre avaliação da tolerância de três espécies de microalgas (Chlorella vulgaris, Haematococcus pluvialis e Scenedesmus subspicatus) cultivadas sob quatro diferentes concentrações simultâneas de CO2 e NOx, para biofixação de GEEs e reaproveitamento da biomassa. A partir de uma contextualização teórica foi possível identificar as principais lacunas relacionadas ao uso de microalgas para a biofixação de GEEs e a necessidade de ampliação das pesquisas biotecnológicas que visem o aprimoramento e/ou desenvolvimento de bioprocessos para o tratamento ambiental e obtenção de diversos produtos com alto valor agregado. Ainda, é necessário explorar as respostas biológicas das espécies cultivadas em processos de reciclagem de nutrientes. Com relação às microalgas avaliadas, Chlorella vulgaris, Haematococcus pluvialis e Scenedesmus subspicatus demonstraram tolerância a diferentes concentrações de CO2 e NOx. O crescimento apresentado foi até 26% maior nos tratamentos com injeção de gás simulado contendo CO2 e NOx, o que corrobora com a hipótese de que as mesmas possuem potencial para a biofixação de GEEs.Universidade PositivoBrasilPós-GraduaçãoPrograma de Pós-Graduação em Biotecnologia IndustrialUPMaranho, Leila Teresinhahttp://lattes.cnpq.br/3269388039410529Arruda, Nicole Machuca Brassac dehttp://lattes.cnpq.br/2555202156228591Miyawaki, Brunohttp://lattes.cnpq.br/4476182188557396Andrade, Walquíria Letícia Biscaia de2021-05-26T12:55:31Z20182021-05-26T12:55:31Z2018info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttps://repositorio.cruzeirodosul.edu.br/handle/123456789/2262porinfo:eu-repo/semantics/openAccessreponame:Repositório do Centro Universitário Braz Cubasinstname:Centro Universitário Braz Cubas (CUB)instacron:CUB2021-06-28T21:40:31Zoai:repositorio.cruzeirodosul.edu.br:123456789/2262Repositório InstitucionalPUBhttps://repositorio.brazcubas.edu.br/oai/requestbibli@brazcubas.edu.bropendoar:2021-06-28T21:40:31Repositório do Centro Universitário Braz Cubas - Centro Universitário Braz Cubas (CUB)false |
