Lignocellulose cell wall fractionation of brewer´s Spent grains with a deep eutectic solvent for Cellulose and xylan isolation and characterization

Description: In this study, isolation of cellulose and xylan from brewer´s spent grains (BSG) biomass using a mixture of choline chloride (ChCl) and glycerol deep eutectic solvents (DES) and autohydrolysis were performed in order to fractionate the lignocellulosic cell wall. The two experiments were done at mild temperatures (105 and 125 ) as comparative studies to analyze their polymers extraction efficiency and biopolymers’ quality.
En el presente estudio se partió del pretratamiento de afrecho de cebada con solventes eutécticos profundos a base cloruro de colina (ClCh) y glicerol (gly) y con autohidrólisis para el aislamiento de xilano y celulosa a dos temperaturas diferentes: 105 y 125 . Los dos pretratamientos fueron realizados para comparar la eficiencia de extracción del primero vs. el segundo...
