Bacterial Cellulose Development

A large number of hydroxyl functional groups on the surface of bacterial cellulose is conducive to improving the doping efficiency after the addition of dopants, and it is also convenient to modify the bacterial cellulose itself to improve its material properties, such as cellulose reaction or grafting required functional groups, to achieve the required particular purpose. Lifeasible provides customers with product development solutions based on the technology and experience of bacterial cellulose. The goal is to help various enterprises accelerate product research and development and provide the application of bacterial cellulose in the energy field.

Background

Bacterial cellulose is a general term for cellulose synthesized by certain microorganisms of Acetobacterium, Soil bacillus, Rhizobium, and Diaphylococcus under different conditions. Bacterial cellulose is a porous mesh nanoscale biopolymer synthesized by microbial fermentation. It is named bacterial cellulose because bacteria synthesize it. It consists of distinctive filamentous fibers that are 0.01 to 0.10 μm in diameter, two to three orders of magnitude smaller than plant cellulose (10 μm). The atomic percentage of carbon elements in bacterial cellulose is higher, up to more than 60 percent. The high carbon content makes the activated carbon material produced as a raw material have excellent electrical properties. At the same time, it can make use of its highly netted and refined fiber structure to make holes to obtain active carbon materials with larger specific surface area to increase its specific capacitance and other electrochemical properties.

The capacitance performance and capacity of the electrode can be investigated, and the internal resistance of the capacitor can be analyzed. The same material under different conditions or materials under the same conditions can be tested through comparative analysis of capacitance performance and optimize the best electrode material preparation method.

How to Obtain Raw Materials for Bacterial Cellulose?

By molecular breeding, strains with glucose as raw material can be screened to produce high-yield bacterial cellulose. By improving the fermentation conditions, the yield of bacterial cellulose can be increased significantly, and the production cost and energy consumption can be reduced.
