Resumo: | Currently, the use of magnetic nanoparticles has aroused interest in industrial processes, and the combination of their properties with the immobilization of lipases has been developed in order to produce carriers of easy separation of the reaction medium. In this context, the objective of the present study was to immobilize Candida rugosa lipase in magnetic nanoparticles, such as magnetite and maghemite, by physical adsorption and covalent bonding. The biocatalysts were evaluated by infrared spectroscopy (FTIR) and hydrolytic activity analysis. Thus, from the analyses performed, the best biocatalyst obtained was the immobilized by covalent bond in maghemite, presenting a hydrolytic activity of 174.67 U/g. |

Nesse contexto, o objetivo do presente estudo foi imobilizar a lipase de Candida rugosa em nanopartículas magnéticas, como magnetita e maghemita, por adsorção física e ligação covalente. Os biocatalicadores foram avaliados por espectroscopia de infravermelho (FTIR) e análise de atividade hidrolítica. Dessa forma, a partir das análises realizadas, o melhor biocatalisador obtido foi o imobilizado por ligação covalente em maghemita, apresentando atividade hidrolítica de 174,67 U/g.Universidade Federal de Viçosa - UFV2020-10-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/jcec/article/view/1085810.18540/jcecvl6iss4pp0498-0504The Journal of Engineering and Exact Sciences; Vol. 6 No. 4 (2020); 0498-0504The Journal of Engineering and Exact Sciences; Vol. 6 Núm. 4 (2020); 0498-0504The Journal of Engineering and Exact Sciences; v. 6 n. 4 (2020); 0498-05042527-1075reponame:The Journal of Engineering and Exact Sciencesinstname:Universidade Federal de Viçosa (UFV)instacron:UFVenghttps://periodicos.ufv.br/jcec/article/view/10858/6060Copyright (c) 2020 The Journal of Engineering and Exact Scienceshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessDomingues, OtávioSantos, Letícia Karen dosHerculano, Rondinelli DonizettiFlumignan, Danilo LuizPaula, Ariela Veloso de2021-02-23T20:11:08Zoai:ojs.periodicos.ufv.br:article/10858Revistahttp://www.seer.ufv.br/seer/rbeq2/index.php/req2/oai2527-10752527-1075opendoar:2021-02-23T20:11:08The Journal of Engineering and Exact Sciences - Universidade Federal de Viçosa (UFV)false |
