The aim of this study was to clarify the role of the relative amounts of hemicelluloses and lignin on the enzymatic hydrolysis of pretreated sugarcane bagasse, by using the glucans/lignin ratio and the glucans/xylans ratio as a quick estimation of th

In this study, the fractionation of sugarcane bagasse at low liquor-solid ratio (LSR) was firstly reported. The effect of low LSR fractionation of sugarcane bagasse by hot water autohydrolysis and organosolv delignification that consume minimal amoun

The melt processing of glycerol-plasticized starch in the presence of non-volatile carboxylic acids resulted in a progressive loss of its molar mass, because the residual moisture in the mixture induced an acid-catalyzed hydrolysis of the ether linka
