Resumo: Immobilized cells have shown advantages in removing hydrocarbons from oil compared to the use of free cells. This work aimed to evaluate the potential of hydrocarbon degradation by bacteria immobilized in support matrices composed of commercial potassium alginate and corn starch. The polymeric immobilizing matrix was developed using dental alginate 2% and corn starch 0.5% and 1%. The matrices have macropores internally, good ability to immobilize cells, increasing baseline respiration (F2 and F3: 4 mg / l CO2 60 days), bacterial biomass (F1: 1.5 x 106 CFU / g 60 days) and the removal of n- alkanes and PAHs of the sediment, when compared to free cells (0 mg / l CO2; 0.3 x 106 CFU / g 60 days). The aromatics hydrocarbons benzo (a) anthracene and anthracene were not degraded. Naphthalene and dibenzo (a) anthracene reached degradation rates of 60% and 80%, respectively. Therefore, the consortium tested and the polymer matrix developed are promising for use in bioremediation of environments contaminated by hydrocarbons.

Este trabajo tuvo como objetivo evaluar el potencial de degradación de hidrocarburos por bacterias inmovilizadas sobre matrices de soporte compuestas por alginato de potasio comercial y almidón de maíz. La matriz polimérica inmovilizadora se desarrolló con 2% de alginato dental y 0,5% y 1% de almidón de maíz. Las matrices tienen macroporos internos, buena capacidad para inmovilizar células, aumento de la respiración basal (F2 y F3: 4 mg / l de CO2 60 días), biomasa bacteriana (F1: 1,5 x 106 UFC / g 60 días) y eliminación de n-alcanos y HAP del sedimento, en comparación con las células libres (0 mg / l CO2; 0,3 x 106 UFC / g 60 días). Los hidrocarburos aromáticos benzo (a) antraceno y antraceno no se degradaron. El naftaleno y el dibenzo (a) antraceno alcanzaron tasas de degradación del 60% y el 80%, respectivamente. Por lo tanto, el consorcio probado y la matriz polimérica desarrollada son prometedores para su uso en la biorremediación de entornos contaminados por hidrocarburos.As células imobilizadas apresentam vantagens na remoção de hidrocarbonetos do petróleo, quando comparadas ao uso de células livres. Este trabalho teve como objetivo avaliar o potencial de degradação de hidrocarbonetos por bactérias imobilizadas em matrizes de suporte compostas de alginato de potássio comercial e amido de milho. A matriz polimérica imobilizadora foi desenvolvida com alginato dental 2% e amido de milho 0,5% e 1%. As matrizes apresentam macroporos internamente, boa capacidade de imobilizar células, aumento da respiração basal (F2 e F3: 4 mg / l CO2 60 dias), biomassa bacteriana (F1: 1,5 x 106 UFC / g 60 dias) e remoção de n-alcanos e HPAs do sedimento, quando comparados às células livres (0 mg / l CO2; 0,3 x 106 UFC / g 60 dias). Os hidrocarbonetos aromáticos benzo (a) antraceno e antraceno não foram degradados. Naftaleno e dibenzo (a) antraceno atingiram taxas de degradação de 60% e 80%, respectivamente. Portanto, o consórcio testado e a matriz polimérica desenvolvida são promissores para uso na biorremediação de ambientes contaminados por hidrocarbonetos.Research, Society and Development2021-12-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2470610.33448/rsd-v10i17.24706Research, Society and Development; Vol. 10 No. 17; e220101724706Research, Society and Development; Vol. 10 Núm. 17; e220101724706Research, Society and Development; v. 10 n. 17; e2201017247062525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/24706/21518Copyright (c) 2021 Carla Jaqueline Silva Sampaio; José Roberto Bispo de Souza; Gilson Correia de Carvalho; Cristina Maria Quintella; Milton Ricardo de Abreu Roquehttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSampaio, Carla Jaqueline SilvaSouza, José Roberto Bispo de Carvalho, Gilson Correia de Quintella, Cristina Maria Roque, Milton Ricardo de Abreu 2022-01-01T11:11:08Zoai:ojs.pkp.sfu.ca:article/24706Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:43:10.570873Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
