摘要： In this work, an edible cellulose-based antibacterial material was prepared by cross-linking alpha-cellulose and kanamycin sulfate via glutaraldehyde to form kanamycin sulfate-glutaraldehyde-cellulose. Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy and X-ray diffraction results indicated that the kanamycin sulfate molecule was cross-linked with the molecular chain of cellulose. The optimal mass ratio of kanamycin sulfate to alpha-cellulose was 1:100 and the degree of substitution reached 1.11%. The optimal kanamycin sulfate-glutaraldehyde-cellulose material showed an excellent inhabitation against both Gram-positive and Gram-negative bacteria. Meantime, the optimal kanamycin sulfate-glutaraldehyde-cellulose had a marked resistance to gastric acid and had low cell cytotoxicity. To promote the application of the kanamycin sulfateglutaraldehyde-cellulose material, the porous microspheres were prepared via the sol-gel method. The particle size of the homogeneous porous microspheres is mainly distributed between 1.5 and 2.0 mu m. Therefore, the kanamycin sulfate-glutaraldehyde-cellulose described herein is a potential edible, eco-friendly, potent, stable, inexpensive, and antibacterial carrier material for delivering drugs, proteins, or vaccines.
