Abstract
The objective of this research were to study the characteristic of silver nanoparticles, the characterictic of silver nanoparticle impregnated on the bacterial cellulose, and the effect of silver nanoparticles toward antibacterial activity of bacterial cellulose and its composites. Bacterial cellulose of rice wastewater is fermented by Acetobacter xylinum for 7 days. The water containing bacterial cellulose is removed by heating in the oven. Bacterial cellulose, bacterial cellulose-chitosan composites and bacterial cellulose-chitosan-glycerol composites had been prepared by immersing dry bacterial cellulose in chitosan and glycerol solution. The silver nanoparticles was prepared by chemical reduction with using silver nitrate solution and tri-sodium citric as reducing agent. UV-Vis spectrometry indicated formation of nanoparticles. To achieve antibacterial activity, silver nanoparticles were impregnated into bacterial cellulosechitosan- glycerol composites by immersing method. Morphology of nanoparticels impregnated in bacterial cellulose-chitosan-glycerol composites was examined by SEM. The antibacterial activity of silver nanoparticles which was impregnated on the bacterial celluloce-chitosan-glycerol was examined by shake flask turbidimetry and clear zone method. The UV-Vis spectroscopy revealed the formation of silver nanoparticles by exhibiting the typical surface plasmon absorption maximum at 419 nm. The SEM image showed that the silver nanoparticles has been impregnated in the surface of bacterial cellulose. The nanoparticles of silver-impregnated bacterial cellulose-chitosan-glycerol composites exhibited antibacterial activity against S.aureus and E.coli.
