Sentence examples for more amorphous cellulose from inspiring English sources
Intensity of absorption at 900 cm–1 by cellulose in SAHT-SSB was higher than by the cellulose in MAHT-SSB showing the presence of more amorphous cellulose in the former.
It indicated that more amorphous cellulose was achieved by hydrothermal pretreatment with increased pretreatment severity.
Nevertheless, Sigmacell 101 is typically chosen as a more amorphous cellulose [ 38].
In this study, the cellulose with more amorphous cellulose exhibited much higher digestibility than cellulose III (Table 1, Additional file 1: Figure S2).
At χ [AMIM]Cl of 0.5, the XRD pattern began to flatten because of the presence of the more amorphous cellulose I.
It has been reported that cellulose I is much more resistant to hydrolyzation than cellulose II or amorphous cellulose [ 27, 28], therefore the enhancement in hydrolysis rate and yield of regenerated cellulose in the following hydrolysis procedure was due to the presence of more amorphous cellulose I in the restructured cellulose after pretreatment.
Paracrystalline cellulose is a form of cellulose that is less ordered than crystalline cellulose but more ordered than amorphous cellulose, and has been proposed to exist on the sub-surface of crystallites as a thin molecular layer [ 43].
It seems reasonably to hypothesize that hemicellulose and, in much more limited extent, amorphous cellulose domains are swollen by liquid hot water whose autoprotolysis activates the depolymerization of the polysaccharides with formation of soluble oligomers that are transferred from the solid to the aqueous phase.
The creation of smaller particles or more amorphous regions on the cellulose might also enhance enzyme adsorption onto the material and hence increase the hydrolysis rate.
The endoglucanases attack more amorphous parts and hydrolyze cellulose from the middle of the chains, acting in synergy with CBHs to hydrolyze the substrate to small oligosaccharides.
One of the challenges for the use of lignocellulosic biomass for bioethanol production is to develop cheap and efficient pretreatment methods that disrupt the lignocellulosic complex making the cellulose more amorphous as well as removing or degrading lignin [ 4].
