Gluconacetobacter strain having cellulose producing activity
View Patent ↗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).
1. An isolated gluconacetobacter strain designated with Accession No: KCCM11078P, and having cellulose producing activity.
2. The gluconacetobacter strain according to claim 1 , wherein the strain having Accession No: KCCM11078P has the 16s rDNA nucleotide sequence of SEQ ID No: 1.
3. A culture of the gluconacetobacter strain according to claim 1 .
4. The culture according to claim 3 wherein said culture comprises cellulose.
5. A composition for cellulose production comprising
at least one selected from the group consisting of the gluconacetobacter strain according to claim 1 ,
a culture thereof,
a concentrate of the strain or the culture, and
a dried product of the strain or the culture.
6. A method for producing cellulose comprising the steps of:
culturing the gluconacetobacter strain according to claim 1 ; and
obtaining cellulose from the culture.
7. The method according to claim 6 , wherein the culturing step of glucoacetorbacter strain having Accession No: KCCM11078P is performed in H.S. medium comprising glucose 20 g/L, yeast extract 5 g/L, peptone 5 g/L, Na2HPO4 2.7 g/L and sodium citrate 1.15 g/L.
8. A method for producing a cellulose-based resin comprising the steps of:
preparing the cellulose produced by the gluconacetobacter strain according to claim 1 ; and
impregnating the cellulose with a resin.
9. The method according to claim 8 , wherein the cellulose-based resin is adapted for a substrate of liquid crystal display (LCD).
