New insights into bacterial cellulose materials: production and modification strategies



Komagataeibacter xylinus cultures produced high amount of bacterial cellulose (BC), which has a structure of nanoporous network of interlaced fibers. When the culture is performed under static experimental conditions, a membrane with characteristics of highly hydrated hydrogel and good mechanical properties is obtained with promissory applications in the biomedical field. Bacterial cellulose films can be used from dermal dressing and even as a controlled drug release system. Besides, stirred cultures of K. xylinus produced amorphous cellulose structures dispersed in the medium with physical and mechanical characteristics different from the membrane. In addition, new properties of BC can be obtained or added if the hydrogel is mixed with other compounds or modified post-purification using both organic and inorganic compounds.
