III
Bacterial cellulose (BC) is a kind of one-dimensional nanomaterial with the chemical essence of dextran produced by bacteria, which has the advantages of high purity, high crystallinity, high mechanical strength, high hydrophilic ability, good biocompatibility and biodegradability, and has been widely used in many fields such as medicine, food, cosmetics and textile. This paper summarized the hydrolysis mechanism of BC enzyme and the cloning and expression of genes, summarized the research results of cellulose structure and function in recent years, and showed the research prospect of bacterial cellulose.
Key words：bacterial cellulose；enzymatic hydrolysis；strength；mechanical strength
