Optimización de la producción de bioetanol en procesos fermentativos del mucílago de Cacao CCN – 51 en un biorreactor tipo batch

Abstract: La biomasa residual no ha sido totalmente valorada y aprovechada en Ecuador desde el punto de vista energético. Ejemplo de ello es el mucílago de cacao que en la actualidad es un residuo sin aprovechamiento útil y rentable. Sin embargo, representa un alto potencial energético en la producción de bioetanol para uso como aditivo en gasolinas. El objetivo de este estudio fue optimizar la producción de bioetanol generado en la fermentación de mucilago de Cacao CCN – 51 con levadura Saccharomyces cerevisiae m… Show more

“…0% obtained a value of 4.20, these results are close to the pH (4.5-5.5) in the publication on the production of ethanol from cassava starch using the strategy of a simultaneous process of saccharification-fermentation [23], but they are lower than the data reported in the investigation of the antioxidant activity of clones of delicate and aromatic cocoa (Theobroma cacao l.) grown in the state of Chiapas-Mexico developed by with values of 5.52-5.90 [24]. Regarding the work on optimising bioethanol production in fermentative processes of CCN51 cocoa mucilage in a batch-type bioreactor by Delgado et, al. (2018) [25], it is similar with a pH value of 4.0.…”

“…Other studies report far lower values. For instance, MJ from CCN‐51 was reported to concentrate 22.06 g L −1 ethanol at 35 °C and pH 4 12 . With Pichia kudriavzevii , 13 g L −1 ethanol was obtained from MJ from a non‐specified cocoa variety 1,35…”

“…De manera opuesta, Loayza (2020) identificó la mayor producción de etanol a partir de la cáscara de cacao a una temperatura 25ºC por un tiempo de tres días, reportando que transcurridos los tres días la producción de etanol baja significativamente. Por otro lado, Delgado et al (2018) reportan que a una temperatura de 35ºC y en un tiempo menor de 3 días (34.5 h) la concentración de etanol alcanza su máximo valor 22,06 g/L para el mucílago del cacao. El rendimiento máximo y la cinética de producción de etanol observada en este estudio refleja resultados que difieren a lo reportado por otros autores.…”
