Abstract

The research and development of Nanocomposites has increased nowadays due to their incredible applications. In this project, the synthesis of Kaolin/gum Arabic nanocomposite was carried out by using the method of solution mixing. The resulted nanocomposite was characterized by using FTIR, SEM and Ultraviolet-visible absorption spectroscopy. Antibacterial activity of the Kaolin, Gum Arabic and synthesized nanocomposite on E.coli and Pseudomonas aeruginosa were carriedout by agar well diffusion method. The Kaolin was observed to have no antibacterial activity, the Gum Arabic and Kaolin/Gum Arabic nanocomposites have remarkable activities on E. coli and Pseudomonas aeruginosa bacteria. The antibacterial activity of Gum Arabic extract on E. coli were found to be 29mm, 18m and 12mm at 100, 50 and 25µg/L concentrations respectively and that of the Kaolin/Gum Arabic nanocomposite were; 16mm, 11mm and 4mm at 100, 50 and 25µ/L concentrations respectively. The antibacterial studies of Gum Arabic extract at various concentrations 100μL, 50μL and 25μg/L were found to be 38mm, 25mm and 14mm respectively for Pseudomonas aeruginosa. Also, the antibacterial activity of Kaolin/Gum Arabic nanocomposite at various concentrations 100μg/L, 50μg/L and 25μg/L were found to be 27mm, 15mm and 9mm respectively Pseudomonas aeruginosa. The result suggests that the Kaolin/Gum Arabic Nanocomposites can serve as a potential antibacterial agent.
