STRUCTURAL ANALYSIS OF BIOSYNTHESIZED CELLULOSE BASED ON THE RESULTS OF CONFOCAL MICROSCOPY
Purpose. To study structural features of biosynthesized cellulose based on the results of the confocal microscopy. Material and design. Biosynthesized cellulose, purified from bacterial products, synthesized Gluconacetobacter xylinus S3, obtained as films with thickness of 1 to 2 mm was analyzed. Its native frozen sections were investigated using direct and inverted confocal microscopes LSM 710, LSM 780 NLO, produced by Carl Zeiss. Results and discussion. Fibers with diameter of 25-220 nm and length of 100 microns are structural base of synthesized cellulose. Macro-fibrious structures with diameter about 100 microns, formed by radially oriented microfibers are to be seen on cross sections.
