Title:
KOMAGATEIBACTER RHAETICUS STRAIN AND CELLULOSE SHEET PRODUCTION METHOD USING SAME
Document Type and Number:
WIPO Patent Application WO/2020/060164
Kind Code:
A1
Abstract:
The present invention provides: a Komagataeibacter rhaeticus KOSS15 strain; a composition comprising the strain or a culture thereof for production of a cellulose sheet; and a method for production of a cellulose sheet, the method comprising a step of culturing the strain. The cellulose sheet produced by the Komagataeibacter rhaeticus KOSS15 strain of the present invention exhibits higher tensile strength and rupture strength than the cellulose sheet of Acetobacter xylinum, which is known as a microorganism having the highest cellulose production yield, and enables a 5-6 fold reduction in the amount of saccharide source necessary for producing a cellulose sheet having the same weight, compared to that of Acetobacter xylinum.
