Abstract:
Disclosed herein is a novel gluconacetobacter strain having cellulose producing activity. Specifically, the present invention relates to a novel gluconacetobacter strain producing nano-structured cellulose in a highly efficient manner. The cellulose produced by the strain, due to its superb thermodynamic properties, can be characterized as nano-structured bacterial cellulose and therefore utilized as a bio-nano-fiber. Particularly, the cellulose can be impregnated with a resin to form a cellulose-based resin which can be effectively adapted for a substrate for a liquid crystal display (LCD).
