Bacterial cellulose and bacterial cellulose-chitosan membranes for wound dressing applications

► Bacterial cellulose (BC) was produced in large scale from culture of Acetobacter xylinum. ► The addition of chitosan (Ch) into BC (BC-Ch) increased the antibacterial activities. ► BC and BC-Ch membranes helped maintain a moist wound healing environment. ► Wounds treated with BC-Ch epithelialized faster than those treated with Tegaderm.
