Abstract

Bacterial cellulose particles were used as a model system to study cellulose-hemicellulose and cellulose-pectin composite formation. A certain strain of Gluconacetobacter xylinus (formerly Acetobacter xylinum) was chosen in this study which is able to produce sphere-like cellulose under agitating condition. In the presence of 0.5% (w/v) xyloglucan, xylan, arabinogalactan and pectin, bacterial cellulose was harvested and characterized. Spherical cellulose was formed in a layered fashion without any additive. Cellulose samples with xyloglucan and pectin showed different morphology compared to other culture conditions. Bacterial cellulose and biomass yield analysis indicated that xyloglucan and pectin stimulated the growth of cellulose. Both X-ray diffraction study and IR spectroscopy showed the changes of crystal structure in cellulose samples with xyloglucan and xylan. These samples were more like the cellulose in higher plants. However, the crystal structure did not change in cellulose samples with pectin and arabinogalactan. In addition, the potential of using hemicelluloses and pectin to increase the production of bacterial cellulose was evaluated.
