A new approach to purification of bacterial cellulose membranes: What happens to bacteria in supercritical media?

In this paper, we report our attempts to elaborate the method of purification and simultaneous sterilization of bacterial cellulose films by means of processing them under high pressure, including supercritical conditions for carbon dioxide, for future application in medicine. Bacterial cellulose films were produced by Gluconacetobacter hansenii. The processed samples were controlled by means of AFM, SEM, EDS, IR spectrometry, elemental and...
