On the supramolecular structure of cellulose allomorphs after enzymatic degradation (original) (raw)
Journal of Optoelectronics and Advanced Materials
The variety of physical structures taken by cellulose molecules in their different crystalline forms is one structural feature of cellulose that has not been examined systematically for its effect on biodegradation. In this paper was demonstrated that the enzymatic degradation reaction of cellulose is adequate not only to demonstrate the influence of the physical structure of the initial material on the heterogeneous reaction, but also to determine the influence of the modifications induced by the chemical treatments of cellulose activation upon the enzymatic hydrolysis. The biodegradation of different celluloses by Trichoderma reesei was investigated. Changes in supramolecular structure of cellulosic residues resulting from enzymatic hydrolysis were established by X-ray diffraction method. The action of the exocellulosic components is demonstrated by the reduction of the dimensions of crystallites for all the allomorphic forms that were studied. The study of X-ray diffractograms sh...
