Abstract: Bacterial cellulose (BC) is an outstanding biomaterial with unique properties, including high water holding capacity, high crystallinity, ultrafine fiber network, high tensile strength in the wet state and the possibility to be shaped into three-dimensional (3D) structures during synthesis. These properties support a wide range of applications, in human and veterinary medicine, odonthology, pharmaceutical industry, acoustic and filter membranes, biotechnological devices and in the food and paper industry. BC is considered biocompatible, presenting an insignificant foreign body reaction; it does not elicit chronic inflammatory responses in vivo. These properties make BC very interesting for tissue engineering applications. Indeed, ongoing research of BC products includes a wide range of biomedical applications: treatment of chronic wounds and burns as temporary coverage, artificial cardiovascular tissues, and guided regeneration of bone, cartilage and nerve.
