UNLABELLED BACKGROUND The enzymatic hydrolysis step converting lignocellulosic materials into fermentable sugars is recognized as one of the major limiting steps in biomass-to-ethanol process due to the low efficiency of enzymes and their cost. Xylanases have been found to be important in the improvement of the hydrolysis of cellulose due to the close interaction of cellulose and xylan. In t...

A new type of polysaccharide (hemicellulose) nanocrystal, bearing the shape an anisotropic nanoflake, emerged from a dimethyl sulfoxide (DMSO) dispersion wood-based xylan through heat-induced crystallization. The dimensions these nanocrystals were controlled by crystallization conditions. Sharp signals in solid-state NMR indicated well-ordered crystal structure. unit cell is constituted two asy...

Background: Plant biomass and agricultural waste products disposal is a serious problem in agriculture based countries. These wastes, usually rich in xylan can be satisfactorily converted to industrially important and useful products by efficient biotechnological application of potent xylanase producing bacteria which generally have high temperature and pH optima....

BACKGROUND Sugar cane internodes can be divided diagonally into four fractions, of which the two innermost ones are the least recalcitrant pith and the moderately accessible pith-rind interface. These fractions differ in enzymatic hydrolyzability due to structural differences. In general, cellulose hydrolysis in plants is hindered by its physical interaction with hemicellulose and lignin. Ligni...
