Cellulose is the most abundant natural biological macromolecular substance on the earth, is a polymer formed by connecting glucose molecules through beta-1,4 glycosidic bonds, is mainly derived from plants such as trees, cotton and the like, and is a main product of plant photosynthesis. At present, cellulose derived from trees and cotton is a main raw material in the fields of paper making industry, textile industry, building industry and chemical industry; cellulose synthesized by plants on earth is hundreds of millions of tons every year, but the synthesized cellulose is not unique to plants, and some bacteria such as acetobacter xylinum, rhizobium, agrobacterium and pseudomonas can synthesize high-purity nano-grade cellulose, also called Bacterial Cellulose (BC), in a heterotrophic manner more efficiently.

The plant source cellulose is usually wrapped by impurities such as lignin, hemicellulose and the like, so that the extraction and refining of the high-purity cellulose are a great technical problem in the industrial field; the bacterial cellulose exists in the form of pure cellulose, and is provided with a nanofiber net consisting of ultramicrofibers, the diameter of the cellulose is between a few nanometers and dozens of nanometers, and is 1-2 orders of magnitude lower than that of other plant source fibers or artificial synthetic fibers; the bacterial cellulose has the characteristics of high purity, high crystallinity, high mechanical strength and elastic modulus, good water absorption and biocompatibility and the like, can be biodegraded, has a plurality of unique properties and functions, becomes a novel biological material, is widely concerned by the scientific community, forms a unique woven structure, has the characteristics of high water absorption and water retention, high transmittance to liquid and gas, high wet strength, in-situ processing and forming particularly under wet conditions and the like due to the nanometer effect.

The high purity and excellent performance enable the bacterial cellulose fiber to be widely applied in special fields; the application in medical materials is as follows: due to good biocompatibility, high mechanical strength in wet state, good liquid and gas permeability and inhibition of skin infections, bacterial cellulose can be used as artificial skin for the temporary dressing of wounds and has also been widely used as surgical and dental materials; the application in food industry is that the bacterial cellulose has strong hydrophilicity, viscosity and stability, can be used as a food forming agent, a thickening agent, a dispersing agent and an anti-dissolving agent, can improve the mouthfeel and can be used as a sausage casing and a framework of certain foods, and becomes a novel important food base material and dietary fiber. For example, in the traditional fermentation process, pure culture of acetic acid bacteria or mixed culture of the acetic acid bacteria and other microorganisms can produce fermented food containing rich cellulose, wherein the Nata de coco is dessert food prepared by fermenting the acetic acid bacteria and rice flour sugar, and is one of the currently 30 popular foods in Japan; in addition, the bacterial cellulose has wide application potential in the aspects of food industry, medical cosmetology, paper making, acoustic equipment, oil exploitation and the like.

The bacterial nano cellulose membrane is a novel product, related products are published at home and abroad at present, but the biggest problem at present is that the product is expensive in price and difficult to form mass consumption products; the price of the product is expensive, mainly because of the low degree of automation.
