Flórez Pardo, Luz Marina; Salcedo M., Jairo G; López Galán, Jorge Enrique (Universidad Nacional de Colombia, 2011-07) -
Evaluation of different methods for efficient extraction of hemicelluloses leaves and tops of sugarcane
Flórez Pardo, Luz Marina; López Galán, Jorge Enrique; González-Córdoba, Andrea (Universidad Nacional de Colombia (Sede Medellín). Facultad de Minas, 2018)En Colombia se producen alrededor de 9 millones de toneladas de residuos de la cosecha de la caña de azúcar por hectárea cada año, que no han sido valorizados hacia ningún tipo de producto. Es necesario conocer su composición, ... -
Influence of pretreatments on crystallinity and enzymatic hydrolysis in sugar cane residues
Luz Marina, Flórez Pardo; López Galán, Jorge Enrique; Salcedo Mendoza, Jairo G. (Brazilian Society of Chemical Engineering, 2019)This research evaluated the effect of different delignification pretreatments (enzymatic and organosolv), on the crystallinity and enzymatic hydrolysis of harvested sugar cane residues. The Crystallinity Index (CrI), the ... -

Significant enzymatic activities in the residues hydrolysis of the sugar cane harvest
Salcedo Mendoza, Jairo Guadalupe; Luz Marina, Flórez Pardo; López Galán, Jorge Enrique (Universidad Nacional de Colombia, Sede MedellínMedellìn, 2019-07)In the production of ethanol from agroindustrial crop residues, one of the critical stages in the process is the conversion of lignocellulosic material to simple sugars, which can be done chemically or enzymatically. In ... -
Using a mediator system to increase the delignification of sugarcane residues with fungal enzymes
Flórez Pardo, Luz Marina; Parra Paz, Angela Sofía; López Galán, Jorge Enrique; Figueroa Oviedo, Jersson Ivan (Instituto Colombiano del Petróleo (ICP) - ECOPETROL S.A., 2015)Industrial residues are resources that generate regional energy security but they have not been sufficiently valued. In southern Colombia, the sugar cane sector produces approximately 9´000 000 T/year of residues, mostly ... -
