S3, preparing a suspension of gram positive staphylococcus aureus (S. aureus) and gram negative escherichia coli (e. coli) in tryptic soy broth and culturing overnight at 37 ℃ and 120 rpm. The concentration of the suspension was then adjusted to 1X 107CFUs/mL are added into trypsin soybean agar, the agar is poured into a sterilized culture dish with the diameter of 55mm, after the agar is solidified, the composite materials under the same treatment condition are respectively placed above an escherichia coli culture medium and a staphylococcus aureus culture medium, the maximum contact is ensured, and the composite materials are cultured for 24 hours at 37 ℃;
s4, measuring the antibacterial activity of the composite material to staphylococcus aureus and escherichia coli under different conditions.
As shown in FIG. 3, the upper four media were E.coli media and the lower four media were Staphylococcus aureus media. It can be seen that the composite material containing the germicide compound produces zones of inhibition (halos) against staphylococcus aureus, and that the zones of inhibition (halos) increase with increasing concentration and treatment time; no inhibition of the composite material to escherichia coli was observed due to the poor antibacterial ability of benzalkonium chloride to gram-negative bacteria; the composite material treated with benzalkonium chloride solution showed antibacterial activity against staphylococcus aureus.
Therefore, the bacterial cellulose textile and the preparation method thereof can solve the problem of difficult biodegradation. The composite material textile prepared from the bacterial cellulose can be recycled, so that the resources are saved, and the environmental pollution is reduced; and in various high-performance or functional textiles, the textile cost of the bacterial cellulose is lower.
