Antibacterial Potential of Bacterial Cellulose Impregnated with Green Synthesized Silver Nanoparticle Against S. aureus and P. aeruginosa

In this study, bacterial cellulose (BC) impregnated with green synthesized silver nanoparticles (AgNPs) is evaluated as an antimicrobial membrane for wound-healing treatment. Green synthesized silver nanoparticles using Moringa oleifera leaf extract were characterized using UV‒visible spectroscopy, FTIR, X-ray diffraction, and transmission electron microscopy. The results confirmed that the resulted particles were Ag(2)O and metallic Ag in nanoscale with an average size ranged from 24 to 40 nm. The green synthesized nanoparticles incorporated within both bacterial cellulose and filter paper discs showed excellent antibacterial activities against Staphylococcus aureus ATCC 6538 and Pseudomonas aeruginosa ATCC 9027. There was no significant difference noticed between bacterial cellulose and filter paper holding capacity to nanoparticles and there was lack of interaction between bacterial cellulose and impregnated nanoparticles as elaborated by Fourier transform infrared spectral analyses. Scanning electron microscopy investigation showed major distortions effects of green synthesized silver nanoparticles on bacterial cell morphology.
