Optimization of enzymatic hydrolysis of wheat straw pretreated by alkaline peroxide using response surface methodology / Benkun Qi in Industrial & engineering chemistry research, Vol. 48 N° 15 (Août 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 15 (Août 2009) . - pp. 7346–7353 Titre : Optimization of enzymatic hydrolysis of wheat straw pretreated by alkaline peroxide using response surface methodology Type de document : texte imprimé Auteurs : Benkun Qi, Auteur ; Xiangrong Chen, Auteur ; Fei Shen, Auteur Année de publication : 2009 Article en page(s) : pp. 7346–7353 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Biomass-wheat  straw  Enzymatic  saccharification  process  Alkaline  peroxide Résumé : To optimize the enzymatic conversion of widely available lignocellulosic biomass-wheat straw (WS), pretreatment facilitating the enzymatic saccharification process was first performed by alkaline peroxide, resulting in a substrate consisting of 60.17% cellulose, 29.53% hemicelluloses, and 4.59% lignin. Using response surface methodology, the combined effects of enzyme loading, substrate concentration, surfactant concentration, and reaction time on hydrolysis yield from enzymatic saccharification of WS were further investigated. The results showed that both enzyme loading and substrate concentration had interactions with surfactant concentration. A quadratic polynomial equation for predicting the hydrolysis yield was developed. The experimental results were in good agreement with predicted values. Therefore, the model could be successfully used to identify the effective combinations of the four factors for predicting hydrolysis yield.
