Influência de compostos fenólicos na fermentação de glicose a etanol por Saccharomyces cerevisiae PE-2 e Saccharomyces cerevisiae de panificação e identificação de seus produtos de bioconversão

Abstract: Agradeço a Deus, presente em nossos corações, pela saúde que nos torna capazes de continuar, mesmo que por caminhos difíceis. Agradeço à minha pequena família, à família da minha casa, àquela que me acompanhou de pertinho nesses anos: Ricardo, Catarina e André. Agradeço também à minha família que vive mais distante, por sempre estarem ao meu lado: meus pais, meus dois irmãos, meus sogros, minhas cunhadas e meus sobrinhos e sobrinhas, em especial à Mila, que nos alegra com sua presença. Agradeço ao meu orientad… Show more

“…The mechanism behind the reduction‐increase‐reduction effect on the ethanol concentration, average productivity in terms of the product (P P ) and yield (η) of the bioprocess, when syringic acid and acetosyringone (0.1, 0.5, and 1.0 g/L) were added to the medium, could not be elucidated with the information collected in this study. Ortiz and Furlani observed a similar behaviour with the addition of the phenolic compounds vanillic acid (0.1, 0.5, and 1.0 g/L) and syringaldehyde (0.6 and 1.0 g/L) respectively. These two authors also worked with S. cerevisiae and did not propose an explanation for the findings.…”

“…When observing the pH results before and after fermentation, it appears that for the banana pulp there was a slight increase in its value, but within the expected for a discontinuous fermentation process, where there is no cell recirculation (CRUZ, 2022), even so, the range is close to the ideal (4.5 to 5.1), as bacterial proliferation occurs much higher, which will compete with the yeasts for the available fermentable sugars and produce other metabolites such as malic acid , glycerol, not being of interest and making the process unfeasible (FURLANI, 2014). However, when observing the pH of the peel, the change was minimal, which suggests when comparing the alcohol content obtained that fermentation did not occur as expected, since despite having sugars in its constitution (NERIS et al, 2018) the presence of other inhibitory compounds, such as the phenolic compounds present in the husks, can significantly affect ethanol productivity (FURLANI, 2014;PEREIRA, 2014).…”
