Bacterial cellulose film and uses thereof
A bacterial cellulose film is provided, including microbial fibers consisting of bacterial cellulose, wherein the microbial fibers are arranged in a density gradient in a direction of the bacterial cellulose film thickness.
1. A method, for producing a bacterial cellulose film, comprises a static fermentation step of Gluconacetobacter, wherein the static fermentation step comprises two-step culture temperature of 25˜28° C. at the first step and 29˜30° C. at the second and starts from initial concentration of Gluconacetobacter in a range of 10 2 -10 5 /ml, and wherein the bacterial cellulose film comprises microbial fibers consisting of bacterial cellulose and the microbial fibers are arranged in a density gradient in a direction of the bacterial cellulose film thickness.
