Description

technical field

[0001] The invention belongs to the technical field of microbes, and in particular relates to the isolation and identification of a bacteria strain producing bacterial cellulose, and the static fermentation culture of bacterial cellulose membranes. Background technique

[0002] Bacterial cellulose (BC) refers to cellulose synthesized by bacteria. It is a polymer compound formed by the polymerization of glucose through β-1,4-glycosidic bonds. Its structure is very close to that of natural cellulose. Compared with cellulose produced by plants, BC has the characteristics of high purity, high crystallinity, high Young's modulus, high water holding capacity, excellent biodegradability and good biocompatibility, so it is expected to be used as a new type of biological material. Degradable materials are used in fields such as food, chemical industry and medicine.

[0003] According to existing reports, microorganisms with BC synthesis function include Gluconacetoba...
