Abstract

The present invention relates to one kind of nano microbial cellulose and the nano microbial cellulose features the size range of 10-1000 nm. The present invention also relates to the preparation process of the nano microbial cellulose. On the other hand, the present invention also relates to the use of the nano microbial cellulose in preparing medicine composition.

Description

field of invention [0001] The invention relates to a nano-microbial cellulose, wherein the nano-microbial cellulose is characterized in that its particle size is in the range of 10-1000 nanometers. The invention also relates to a method for preparing the nano microbial cellulose. Another aspect of the present invention relates to the use of the nano-microbial cellulose for preparing a pharmaceutical composition. Background of the invention [0002] Fruit juices such as coconut water and apple juice are rich in nutrients and can be drunk directly. In addition, the fruit juice can also be used to produce microbial cellulose gel, which can be used in food, beverage and other industries. As Byrom et al. (EP0279506A1) reported that Acetobacter xylinum (Acetobacter xylinum) acts on a specific medium to prepare extracellular microbial cellulose, Brown et al. (EP0258038A2) also reported the use of specific microorganisms to prepare microbial cellulose method. But ordinary microb...
