ABSTRACT
Bacterial cellulose is a polysaccharide synthesized by Acetobacter xylinum; it grows on the air-liquid surface of culture medium not only in a static culture but also in shaking condition and stirring bioreactor. The popular strain Acetobacter xylinum is a key player for the production of bacterial cellulose. Bacterial cellulose has numerous applications in industrial sectors as it is easy to produce from low-cost culture and because of its qualified abilities, ease of decomposition by microorganisms in the environment, and renewability. Therefore, it has been also applied in many industrial processes such as the food industry, medical materials industry, paper industry, textile industry, electrical applications, and composites industry. Bacterial cellulose in food sector is popularly known as nata de coco. The Philippine dessert nata de coco has been manufactured as a cottage industry. Both to deliver drug and to absorb exudates, transdermal delivery systems that can work bilaterally represent a very exciting opportunity for the application of bacterial cellulose membranes.
