Bacteria cellulose producing bacteria and method for preparing bacteria cellulose using above bacterial strain

The invention provides bacterial cellulose (BC) producing bacteria and a method for preparing the bacterial cellulose by using the bacterial strain. The bacterial strain is a selected gluconic acid acetobacter xylinum GD-BC-1 with an accession number of CCTCC M 208149. The method is to use the bacterial strain as a fermentation bacterial strain and use glucose as a main fermentation material for fermentation so as to obtain the BC. The preparation method comprises the following steps of: activating a slant bacterial strain, liquid-activating the slant bacterial strain, inoculating the liquid-activated slant bacterial strain in a fermentation culture medium to perform dynamic or static fermentation and extracting products of BC from the fermentation solution. The preparation method uses the bacterial strain of gluconic acid acetobacter xylinum GD-BC-1 with the accession number of CCTCC M 208149 for fermentation so as to produce the BC. The BC can be produced through dynamic or static fermentation in a conical flask with glucose as the main fermentation material, and the yield is high and different methods can be used in different production environment to produce BC.
