Abstract

Comparison of microcrystallites morphological structure of microcrystalline cellulose specimens obtained hydrolytically from plant and bacterial cellulose microfibrils is described. Micromorphological characteristics of the structures are visualized using SEM Sigma VP ZEISS scanning electron microscopy. The crystallinity degree of the microcrystalline cellulose specimens is calculated by new method using X-ray diffractometry (XRD-7000S diffractometer). Native bacterial cellulose is obtained on the glucose media using symbiotic complex of yeast and bacteria A.xylinum. It was found, that average diameter of bacterial cellulose microfibrils decreases during acid hydrolysis from 34.0 nm to 16.6 nm without shortening in length. Consequently, substantially amorphous parts are localized on the surface of the microfibrilles. The microcrystallites from bacterial cellulose are more elongated while cotton microcrystalline cellulose has short fusiform size of the microcrystallites at an average diameter 21.2 nm. The amorphous and crystalline parts regularly alternate in the microfibrils of plant cellulose. The length of the fusiform cotton microcrystallites is about 200-300 nm after the hydrolysis of amorphous part of the microfibrils.
