Resumo: This work had the purpose of evaluating the efficiency of the pretreatment with alkaline hydrogen peroxide of pineapple bagasse in order to obtain fermentable sugars by applying acid and enzymatic hydrolysis to said residue. Four experimental designs were applied to study the best conditions for the pre-treatment. Total reducing sugars (TRS) concentration was the response and hydrogen peroxide concentration, time and temperature were the independent variables. The studies were conducted using pineapple bagasse with particle sizes of 20 mesh and 48 mesh. Acid saccharification, with 2.9% sulfuric acid (v/v), following the pre-treatment, yielded TRS concentrations that reached 0.094 g of TRS/g of raw bagasse for 20 mesh and 0.101 g of TRS/g of raw bagasse for 48 mesh. The enzymatic saccharification, with 9 FPU/g cellulase and 2% (m/v) of bagasse, reached 0.063 g of TRS/g of raw bagasse for both particle sizes. The peroxide concentration showed a significant influence, the use of high concentrations reduced the TRS output in both hydrolysis. With the results found in this work, it is possible to infer the feasibility of applying pineapple bagasse as a lignocellulosic raw material.

Se aplicaron cuatro diseños experimentales para estudiar las mejores condiciones para el pretratamiento. La concentración de azúcares reductores totales (TRS) fue la respuesta y la concentración de peróxido de hidrógeno, el tiempo y la temperatura fueron las variables independientes. Los estudios se realizaron utilizando bagazo de piña con tamaños de partículas de malla 20 y malla 48. La sacarificación ácida, con 2.9% de ácido sulfúrico (v / v), luego del pretratamiento, arrojó concentraciones de TRS que alcanzaron 0.094 g de TRS / g de bagazo crudo para malla 20 y 0.101 g de TRS / g de bagazo crudo para malla 48. La sacarificación enzimática, con 9 FPU / g de celulasa y 2% (m / v) de bagazo, alcanzó 0.063 g de TRS / g de bagazo crudo para ambos tamaños de partícula. La concentración de peróxido mostró una influencia significativa, el uso de altas concentraciones redujo la salida de TRS en ambas hidrólisis. Con los resultados encontrados en este trabajo, es posible inferir la factibilidad de aplicar bagazo de piña como materia prima lignocelulósica.Este trabalho teve como objetivo avaliar a eficiência do pré-tratamento com peróxido de hidrogênio alcalino de bagaço de abacaxi para a obtenção de açúcares fermentáveis ​​por meio da aplicação de hidrólise ácida e enzimática sobre o referido resíduo. Quatro projetos experimentais foram aplicados para estudar as melhores condições para o pré-tratamento. A concentração de açúcares redutores totais (TRS) foi a resposta e a concentração de peróxido de hidrogênio, o tempo e a temperatura foram as variáveis ​​independentes. Os estudos foram conduzidos com bagaço de abacaxi com granulometria de 20 mesh e 48 mesh. A sacarificação ácida, com 2,9% de ácido sulfúrico (v / v), após o pré-tratamento, rendeu concentrações de TRS que alcançaram 0,094 g de ATR / g de bagaço bruto para 20 mesh e 0,101 g de ATR / g de bagaço bruto para 48 mesh . A sacarificação enzimática, com 9 FPU / g de celulase e 2% (m / v) de bagaço, atingiu 0,063 g de TRS / g de bagaço bruto para ambos os tamanhos de partícula. A concentração de peróxido apresentou influência significativa, o uso de altas concentrações reduziu a produção de TRS em ambas as hidrólises. Com os resultados encontrados neste trabalho, é possível inferir a viabilidade da aplicação do bagaço de abacaxi como matéria-prima lignocelulósica.Research, Society and Development2021-01-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/990210.33448/rsd-v10i1.9902Research, Society and Development; Vol. 10 No. 1; e4921019902Research, Society and Development; Vol. 10 Núm. 1; e4921019902Research, Society and Development; v. 10 n. 1; e49210199022525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/9902/10785Copyright (c) 2021 Danielle Pires Nogueira; Lorena Costa Vasconcelos; Gabriel Luis Castiglioni; Fernanda Ferreira Freitas; Araceli Aparecida Seolattohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessNogueira, Danielle Pires Vasconcelos, Lorena Costa Castiglioni, Gabriel LuisFreitas, Fernanda Ferreira Seolatto, Araceli Aparecida2021-02-20T21:19:23Zoai:ojs.pkp.sfu.ca:article/9902Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:32:04.723874Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
