Bacterial cellulose (BC) has an advantage as an engineering material with excellent mechanical properties and purity. In particular, compared to the existing cellulose produced by pretreatment of wood, BC is a natural material produced by microorganisms and is an eco-friendly material that can be produced without destroying forests. The lack of technology to control BC's physical properties has been one of the reasons that has hindered its industrial use. This study reports that the physical properties of BC change as the carbon sources used for BC production by Komagataeibacter sucrofermentans DSM 15973 change. When it grew with four carbon sources; glucose, fructose, sucrose, and glycerol, the physical properties of BC, such as crystallinity, fiber morphology, specific surface area, thermal stability, and mechanical strength were compared. |
