Abstract:
The single factor and orthogonal experiments were made and the optimum media and conditions of producing bacterial cellulose with Acetobacter Xylinum1. 1812was obtained as follows: sucrose 5 %, protein peptone 1. 5 % , citric acid 0. 2 % , Na2HPO4?12H2O 0. 2 % , KH2PO4 0. 2 % , MgSO4?7H2O 0. 03 %, alcohol 1 % , pH 618, and cultivation at 28 ℃ for 6 days. The yield is 2 g/L.The crude cellulose was obtained by filtering, washing by 4 % NaOH solut ion, washing by distilled water and 0. 5 % CH3COOH many times.The cellulose was isolated by Sephadex G- 150 column chromatograpy. It is found that the cellulose. s onent is single.
