Abstract

Provided is a cellulose composition, including a plurality of biocelluloses, wherein a diameter of the biocelluloses ranges from 20 to 30 nanometer, and a length of the biocelluloses ranges from 2000 to 3000 nanometer. The biocelluloses have good biocompatibility and can effectively enhance the efficiency of absorption and transmission of substances.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A cellulose composition, comprising a plurality of biocelluloses formed by bacteria having a diameter of from 20 nm to 30 nm and a length of from 2000 nm to 3000 nm, and a liquid medium, wherein the plurality of the biocelluloses are in an amount of from 0.5% by weight to 1.2% by weight, based on a total weight of the cellulose composition, and wherein the plurality of the biocelluloses does not agglomerate. 
     
     
         2 . The cellulose composition of  claim 1 , wherein the liquid medium is water. 
     
     
         3 . The cellulose composition of  claim 2 , which has an OD620 value of from 0.29 to 1.22 when being dispersed in 0.1 ml of the water. 
     
     
         4 . The cellulose composition of  claim 3 , wherein the OD620 value is from 0.43 to 1.22. 
     
     
         5 . The cellulose composition of  claim 2 , wherein a contact angle of the cellulose composition with a surface of a sealing wax film is from 95.5° to less than 107°. 
     
     
         6 . A cellulose composition, comprising a plurality of biocelluloses formed by bacteria having an aspect ratio of from 66 to 150, and a liquid medium, wherein an OD620 value of the cellulose composition is from greater than 0.29 to 1.22, wherein the plurality of the biocelluloses are in an amount of from 0.5% by weight to 1.2% by weight, based on a total weight of the cellulose composition, and wherein the plurality of the biocelluloses does not agglomerate. 
     
     
         7 . The cellulose composition of  claim 6 , wherein the liquid medium is water. 
     
     
         8 . The cellulose composition of  claim 7 , wherein a contact angle of the cellulose composition with a surface of a sealing wax film is from 95.5° to less than 107°.
