When the KHCO3 was introduced during the pyrolysis process, the plentiful hydroxyl in cellulose and hemicellulose underwent dehydration condensation among different parent polymers, which are responsible for the formation of macroporous structure. By contrast, The β-O-4 bands in lignin experience homolys...
Chemical images of cellulose, hemicelluloses and lignin that can be intuitively linked to tissue structure were produced based on FTIR microspectroscopic imaging with diagnostic spectral peaks. The principal components analysis was then applied to reveal the major spectral variances among different tissues...
In this work, wheat bran was used as cellulosic filler in biocomposites based on natural rubber. The impact of wheat bran content [ranging from 10 to 50 parts per hundred rubber (phr)] on processing, structure, dynamic mechanical properties, thermal properties, physico-mechanical properties and m...
Cellulose-hemicellulose and cellulose-lignin interactions during pyrolysis at gasification temperature (800℃) were investigated with various cellulose samples mixed with hemicellulose (glucomannan or xylan) or milled wood lignin. Significant interactions were observed in cellulose-lignin pyrolysis; lignin inhibi...
The NDF, ADF, cellulose, hemicellulose and lignin contents of five frozen vegetables (raw and boiled) and five canned vegetables (two of them fried) have been studied. In general, it was observed that boiling resulted in an increase in the NDF, ADF and cellulose content. There was also a...
of the biomas samples were discussed in terms of the thermal degradation of the main components of the biomass, cellulose, hemicellulose and lignin. Copyri... AR Reed,PT Williams - 《International Journal of Energy Research》 被引量: 119发表: 2004年 Hemicellulose, cellulose and lignin interaction...
Evidence shows that bacteria contribute actively to the decomposition of cellulose and hemicellulose in forest soil; however, their role in this process is still unclear. Here we performed the screening and identification of bacteria showing potential ce
This study focused on the effect of hemicellulose and lignin on enzymatic hydrolysis of dairy manure and hydrolysis process optimization to improve sugar yield. It was found that hemicellulose and lignin in dairy manure, similar to their role in other lignocellulosic material, were major resistive fac...
Lignin is linked to both hemicellulose and cellulose, forming a physical seal that is an impenetrable barrier in the plant cell wall. It is present in the cellular wall to give structural support, impermeability and resistance against microbial attack and oxidative stress. It is an amorphous ...
In straw cell walls, cellulose exists as microfibrils of indefinite length and varying degrees of crystallinity and is embedded in a gel matrix composed of hemicellulose, lignins, and other carbohydrate polymers. Cellulose microfibrils are of great importance in straw tissues and make the major ...
