Nowadays, the development of bioproducts with high added value, especially when they encourage processes that generate innovative products, applicable to health, sustainable and that bring significant improvements to existing products and processes, have gained much attention. Therefore, there is a trend in researches in the production and application of bioproducts, such as dressings, because they promote patient comfort, especially for pain relief. In this context, the bacterial nanocellulose can be applied as skin dressing for treatment of ulcerative lesions, it relieves pain, protects against bacterial infections and contributed in the process of the tissue regeneration. A promising and innovative alternative to optimize the benefits attributed to bacterial nanocellulose would be its association with polymer composites, such as fibroin; and further, the biomolecules which have antimicrobial activity, antioxidant, among others; in order to overcome their limitations and increase its applications areas. For this reason, the aim of this study it will be to develop and evaluate the properties of a bioproduct created from the combination of nanocellulose with fibroin , further add a biomolecule (bromelain). The bromelain is a proteolytic enzyme used in the food industry and medicine. For this reason, the methodologies were design in three phases, where phase 1 will produce the nanocellulose, produce fibroin; and start the bromelain extraction system by aqueous two phases. Phase 2 will start the biomaterial production, biomolecule stability after extraction. Following for Phase 3, will development the bromelain, after extraction by aqueous two-phase system, incorporation and release in the biomaterial (fibroin and bacterial nanocellulose); the bioproduct mechanical and physicochemical characterization; and biological assays. As a result, we look forward the development a platform for the production and purification of bioproducts, with high properties to apply in wound care. (AU)
