Embodiment 1
[0048] 1) Selected strains
[0049] Select Gluconoacetobacter xylinum 323 as the model strain, activate the model strain to prepare Acetobacter xylinum seed mash with a concentration of 5%, and inoculate the Acetobacter xylinum seed mash into the coconut water fermentation medium to make wood-containing Initial fermentation broth of an active strain of Acetobacter.
[0050] 2) Aerobic fermentation
[0051] Put the initial fermentation broth into a culture tank with a height of 30mm in the coconut water fermentation medium liquid layer, and put it into a constant temperature incubator at 29°C together with the culture container to cultivate for 2 days. At the same time, the oxygen supply valve is opened, and medical oxygen with a pressure of 0.075 MP is continuously introduced to the top of the culture tank, and bacterial cellulose membranes with a thickness of about 0.2 mm are harvested.
[0052] 3) Purification treatment
[0053] Soak the bacterial cellulose membrane with ...

Embodiment 3
[0086] 1) Model strain
[0087] Select Gluconacetobacter xylinum 323 as the model strain, activate the model strain to prepare Acetobacter xylinum seed mash with a concentration of 5%, and inoculate the Acetobacter xylinum seed mash into the coconut water fermentation medium to make wood-containing Initial fermentation broth of an active strain of Acetobacter.
[0088] 2) Fermentation culture
[0089] Put the initial fermentation broth into a culture tank with a height of 30 mm in the coconut water fermentation medium liquid layer, and put it into a constant temperature incubator at 28° C. for cultivation for 2 days together with the culture container. At the same time, the oxygen supply valve was opened, and medical oxygen with a pressure of 0.075 MP was continuously introduced to the top of the culture tank, and bacterial cellulose membranes with a thickness of about 1 mm were harvested.
