3D bacterial cellulose biofilms formed by foam templating

Schematic of the bacterial cellulose foam formation process. G. xylinus extrudes bacterial cellulose as a function of oxygen and migrates toward the air–water interface. To construct a bacterial cellulose foam, a suspension of G. xylinus in growth media is foamed. The air bubbles are stabilized through interfacial stabilization by Cremodan. To avoid water drainage and to enhance stability of the foam Xanthan is added as a thickener. After bacterial growth, the foam was increasingly stabilized by BC formation leading to stable cellulose foam structures after 4 day
