The roles of xylan and lignin in oxalic acid pretreated corncob during separate enzymatic hydrolysis and ethanol fermentation
(ELSEVIER SCI LTD, 2010)
High yields of hemicellulosic and cellulosic sugars are critical in obtaining economical conversion of agricultural residues to ethanol. To optimize pretreatment conditions, we evaluated oxalic acid loading rates, treatment ...
Evaluation of lime and hydrothermal pretreatments for efficient enzymatic hydrolysis of raw sugarcane bagasse
(2015-12-02)
Background: Ethanol production from sugarcane bagasse requires a pretreatment step to disrupt the cellulose-hemicellulose-lignin complex and to increase biomass digestibility, thus allowing the obtaining of high yields of ...

Xylan extraction from pretreated sugarcane bagasse using alkaline and enzymatic approaches
(BioMed Central, 2017)
Abstract
Background
New biorefinery concepts are necessary to drive industrial use of lignocellulose biomass components. Xylan recovery before enzymatic hydrolysis of the ...
Production of biodiesel from crude palm oil by a sequential hydrolysis/esterification process using subcritical water
(2019-01-01)
This paper investigates the biodiesel production by subcritical/chemical hydroesterification from crude palm oil. Hydroesterification is the innovation of biodiesel production in two-step: consists of hydrolysis of oil ...
