Acetylation of bacterial cellulose: Preparation of cellulose acetate having a high degree of polymerization

Cellulose triacetate prepared from bacterial cellulose of Acetobacter xylinum subsp. sucrofermentans BPR3001A showed a higher degree of polymerization and higher mechanical strength than that from the cotton linter. The fine fibrils of bacterial cellulose required only a short time for acetylation which preserved the high degree of polymerization.
