dc.descriptionCon el fin de fortalecer el desarrollo de procesos biológicos que sustituyan y disminuyan la dependencia a los combustibles fósiles, se ha venido estudiando hace unos años en el concepto de biorefinería, un esquema de aprovechamiento de residuos para la obtención de energía y productos de valor agregado. Ante esto, el presente trabajo se centró en el estudio de la fracción liquida de la fermentación oscura de residuos agroindustriales, con el objetivo de tener conocimiento sobre las rutas metabólicas y la bioconversión de productos metabólicos que se puedan aprovechar para considerar la fermentación oscura como proceso principal de una biorefinería. Teniendo en cuenta lo anterior, se caracterizó y cuantifico la fracción liquida del proceso de fermentación oscura a partir de la técnica química de HPLC. Se idéntico el ácido acético, propiónico, butírico y láctico como productos metabólicos. La fermentación tipo lactato se identificó como desviación de la ruta predominante y la fermentación tipo acetato-butirato se identificó como productos mayoritarios en la mayoría de las mezclas.spa
dc.description.abstractIn order to strengthen the development of biological processes that substitute and reduce dependence on fossil fuels, the concept of biorefinery has been studied a few years ago. A scheme to use waste to obtain energy and value-added products. Given this, the present work focused on the study of the liquid fraction of the dark fermentation of agroindustry residues, with the objective of having knowledge about the metabolic routes and the bioconversion of metabolic products that can be used to consider dark fermentation as a process main of a biorefinery. Taking into account the above, the liquid fraction of the dark fermentation process was characterized and quantified from the chemical HPLC technique. Acetic, propionic, butyric and lactic acid were identified as metabolic products. Lactate-type fermentation was identified as a deviation from the predominant route and acetate-butyrate-type fermentation was identified as major products in most mixtures.spa
