Fabrication and characterization of novel bacterial cellulose/alginate/gelatin biocomposite film.

Hydrogels from bacterial, algal, and animal cells-bacterial cellulose (BC), alginate, and gelatin, respectively-were combined to fabricate a biocomposite film (BCAGG) via an eco-friendly casting technique. In addition, glycerol was added as a plasticizer to improve the elasticity and water absorption capacity of the film. In this study, BC pellicles were simply deconstructed into fibrils suspension and then reconstructed into films with a supplement of alginate, gelatin and glycerol.

Biosynthesis and Characterization of Nanocellulose-Gelatin Films.

A nanocellulose-gelatin (bacterial cellulose gelatin (BCG)) film was developed by a supplement of gelatin, at a concentration of 1%-10% w/v, in a coconut-water medium under the static cultivation of . The two polymers exhibited a certain degree of miscibility. The BCG film displayed dense and uniform homogeneous structures.
