Example Embodiment
[0031] Example 1: Preparation of Bacterial Cellulose Hydrogel Modified by Chitosan In Situ Coating
[0032] preparation process such as image 3 shown, with the following steps:
[0033] (1) Preparation of standard HS culture solution: Weigh 4g of glucose, 1g of yeast powder, 0.54g of disodium hydrogen phosphate, 0.23g of citric acid and dissolve them in ultrapure water to prepare 200mL of standard HS culture solution;
[0034] (2) Add 2 g of chitosan (molecular weight about 100,000) to the standard HS culture solution, stir well, and after dispersing and mixing, sterilize by autoclaving, and the chitosan turns brown.
[0035] (3) Inoculate 5 mL of Acetobacter xylinum (American Standard Bacteria Bank ATCC 53582) bacterial solution in the standard HS culture solution containing chitosan described in step (1), and cultivate in a 30°C constant temperature incubator for 10 days to obtain chitosan Bacterial cellulose hydrogel modified by sugar coating, showing a two-layer structu...
Example Embodiment
[0040] Example 2: Preparation of Bacterial Cellulose Hydrogel Modified by Chitosan In Situ Coating
[0041] Based on Example 1, the differences are: the amount of chitosan in step (2) is changed to 4 g, the incubation time in step (3) is changed to 15 days, and the rest are the same as in Example 1.
Example Embodiment
[0042] Example 3: Preparation of Bacterial Cellulose Hydrogel Modified by Chitosan In Situ Coating
[0043] Based on Example 1, the differences are: the amount of chitosan in step (2) is changed to 6 g, the incubation time in step (3) is changed to 5 days, and the rest are the same as in Example 1.
