Resumo: | For decades, non-renewable energy resources have been used indiscriminately, but their slow depletion and extremely harmful impacts on the environment have shifted the focus to sustainable and renewable energy sources. Among the renewable energy sources, biofuel cells are defined as devices that convert chemical energy present in chemical bonds into electrical energy. Biocells are classified into two broad categories of enzymatic fuel cells, which employ enzymes as biocatalysts, and microbial fuel cells, which use microorganisms as biocatalysts. An important requirement in the functioning of a biofuel cell is the transfer of electrons from inside an active site of an enzyme to the outside, as the electrodes being solid cannot penetrate the enzymes. A wide range of molecules can be used as electrochemical mediators, some with high toxicity and many non-toxic fungal substances having an enormous potential to be used as electrochemical mediators. In this work, the fungal pigment bikaverin was compared to the synthetic dye Congo red, in order to obtain the best energy-optimizing molecule in an enzymatic fuel cell. Congo red presented a higher current density of 273 mA.cm-2 compared to bikaverin, 230 mA.cm-2, but because it presents a more stable chronoamperometric graph and does not have high toxicity, the fungal biopigment proved to be the best option for optimization. on the potential of energy generated in an enzymatic fuel cell. |

Entre las fuentes de energía renovables, las celdas de biocombustibles se definen como dispositivos que convierten la energía química presente en los enlaces químicos en energía eléctrica. Las bioceldas se clasifican en dos amplias categorías de celdas de combustible enzimáticas, que emplean enzimas como biocatalizadores, y celdas de combustible microbianas, que utilizan microorganismos como biocatalizadores. Un requisito importante en el funcionamiento de una celda de biocombustible es la transferencia de electrones desde el interior de un sitio activo de una enzima hacia el exterior, ya que los electrodos al ser sólidos no pueden penetrar las enzimas. Se puede usar una amplia gama de moléculas como mediadores electroquímicos, algunas con alta toxicidad y muchas sustancias fúngicas no tóxicas que tienen un enorme potencial para usarse como mediadores electroquímicos. En este trabajo se comparó el pigmento fúngico bicaverina con el colorante sintético rojo congo, con el fin de obtener la mejor molécula optimizadora de energía en una celda de combustible enzimática. El rojo congo presentó una mayor densidad de corriente de 273 mA.cm-2 en relación a la biverina, 230 mA.cm-2, pero por presentar un gráfico cronoamperométrico más estable y no tener alta toxicidad, el biopigmento fúngico demostró ser la mejor opción para optimización del potencial de energía generada en una pila de combustible enzimática.Há decadas, recursos energéticos não renováveis estão sendo usados indiscriminadamente, mas seu lento esgotamento e impactos extremamente prejudiciais ao meio ambiente mudaram o foco para fontes de energia sustentáveis e renováveis. Dentre as fontes renováveis de energia, as biocélulas a combustível são definidas como dispositivos que convertem a energia química presente nas ligações químicas em energia elétrica. As biocélulas são classificadas em duas grandes categorias de células a combustível enzimáticas, que empregam enzimas como biocatalisadores e células a combustível microbianas, que usam micro-organismos como biocatalisadores. Um requisito importante no funcionamento de uma biocélula a combustível, é a transferência de elétrons de dentro de um sítio ativo de uma enzima para fora, pois os eletrodos sendo sólidos não podem penetrar nas enzimas. Uma vasta gama de moléculas pode ser usada como mediadores eletroquímicos, algumas com toxicidade elevada e muitas substangias fúngicas atóxicas contendo umenorme potencial para serem utilizados como mediadores eletroquímicos. Neste trabalho o pigmento fúngico bicaverina foi comparado ao corante sintético vermelho congo, a fim de obter a melhor molécula otimizadora de energia em uma célula a combustível enzimática. O vermelho congo apresentou maior densidade de corrente 273 mA.cm-2 em relação a bicaverina, 230 mA.cm-2, porém por apresentar um gráfico cronoamperométrico mais estável e não ter elevada toxicidade, o biopigmento fúngico se mostrou a melhor opção para otimização no potencial de energia gerada em uma célula a combustível enzimática.Research, Society and Development2022-07-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/3213210.33448/rsd-v11i10.32132Research, Society and Development; Vol. 11 No. 10; e51111032132Research, Society and Development; Vol. 11 Núm. 10; e51111032132Research, Society and Development; v. 11 n. 10; e511110321322525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/32132/27533Copyright (c) 2022 Paulo Henrique da Silva; Ilka Djanira Ferreira do Nascimento; Galba Maria de Campos-Takakihttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSilva, Paulo Henrique da Nascimento, Ilka Djanira Ferreira do Campos-Takaki, Galba Maria de2022-08-12T22:23:03Zoai:ojs.pkp.sfu.ca:article/32132Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:48:13.874034Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
