Bacterial cellulose has remarkable properties. It has outstanding mechanical strength. It is biocompatible and biodegradable. We would like to use these outstanding properties in a foam structure. The wet foam has direct applications in the biomedical industries because of … the high water absorption capabilities and its inherent biocompatibility. The wet foams can also be used as a filter material due to its porous nature. And yet there is another application: We can freeze-dry them to create strong and porous materials … for lightweight engineering applications. Bacterial cellulose is produced by bacteria directly at the water-air interface … with oxygen and sugar as nutrients. We use this capability of the bacteria to form these celulose films at the interface … by enlarging the interface in a foaming process. We add a surfactant and a thickener. Both of them are food grade. We can create a stable foam template where the bacteria can successfully grow in. We can grow the cellulose foam into different shapes. The foam takes the shape of the mould. Bacterial cellulose is non-toxic. You can eat it.
