Abstract :
In this study, cellulose nanocrystals (CNC) was prepared and mesotetrakis(4nitrophenyl)porphyrin (TNPP) was immobilized on it. The product was identified by techniques of UV-Vis, fourier transform infrared (FTIR), diffuse reflectance UVVis spectroscopy (DRS), energydispersive Xray spectroscopy (EDX) and scanning electron microscopy (SEM). The effect of an amount of a loaded porphyrin compound containing the nitro group on CNC was investigated against a typical Gram negative bacterium, Pseudomonas aeruginosa, and a typical Gram positive bacterium, Bacillus subtilis, under visible light irradiation. The results indicated that CNC incorporated with 14.9% TNPP has a good effect on the photoinactivation of P. aeruginosa and can be used in the textile, biomedicine, biomaterials engineering, membranes and polymer nanocomposites.
