The use of sustainable and renewable feedstock materials has a great interest in the production of various polymers and materials for various biomedical applications. Bacterial cellulose (BC) is a natural biomaterial produced from bacteria with a nanofibrous three-dimensional(3D) cellulose network. The properties of BC production depend on the use of culturing media, growth parameters, and bacterial strain. This study used an aqueous extract of the rotten banana pulp as sole carbon energy to produce BC sheets in a static culture using Gluconacetobacter hansenii. The developed BC sheets were characterized by XRD, SEM, FTIR, TGA, and tensile measurements. The results showed that the produced BC sheets exhibited a good 3D morphology network, superior hydration, and excellent mechanical properties. Moreover, the drug-loaded BC sheets showed sustainable release of drugs, and BC-dopamine sheets also showed good cytocompatibility for the culturing of fibroblasts for skin tissue engineering. |
