Bacterial cellulose and its modification to cellulose sulfate: determination of molar mass by viscometry

Popis výsledku v původním jazyce

Bacterial cellulose (BC) has unique physical and biocompatible properties, thus it is recommended to be used as a functional material. In comparison to plant cellulose, BC is chemically pure without hemilellulose and lignin. BC fibers exhibit a high crystalline nanostructure, tensile strength and good moldability. BC is non-alergic, non-toxic and non-pyrogenic and due to these features it can be used in healing application. BC can also serve as a source for derivatives preparation, like cellulose sulfate (CS), a polysaccharide, has various biomedical applications such as formation of microcapsules for cell encapsulation. We used bacterial strain Gluconanetobacter xylinus3611 as a producer of BC. The molar mass of BC was determined under given condition. Freeze-dried BC was modified by sulfonation reaction and the degree of sulfonation and molar masses were characterized. The molar masses were determined by viscometry which indicates the correlation between the molar masses of pure and
