In addition, it has called attention for uses such as membrane for wound care and tissue engineering. In this work, the bacterial cellulose fermentation process is modified by the addition of natural materials before the bacteria are inoculated. In vivo behavior using natural ECM for regenerative medicine is presented and completed wound healing process is 3 months.展开更多
