CONCLUSIONSAs a result of the studies we performed, it has been found that bacterial cellulose, like spruce cellulose, is soluble in an aqueous NaOH solution with an 8.5% concentration at a temperature of - 5°C if the polymerization degree of the cellulose does not exceed 400. When, however, 1% of urea is added to the 8.5% NaOH solution, the solubility of cellulose is considerably increased. In this solvent, bacterial cellulose may be dissolved so longas its polymerization degree is below 560.
