Abstract
Liquid loaded pads useful as wound and burn dressings are prepared from pellicles of microbially-produced cellulose obtained, for example, by culturing Acetobacter xylinum. A pellicle having a thickness from about 0.1 to 15 millimeters or greater is processed to replace the culture medium with water or other physiologically compatible liquid. The liquid-loaded pellicle is sterilized prior to its use as a dressing or in other medical applications.
