The Study of Polyurethane Modified with (Peel the Garlic , Cooked Tea Leaves and Ash Firewood) as Antibacterial Polymer

Abstract

In this present paper, experimental results on anti-bacterial efficacy of poly urethane foam  added to various contents of Peel the garlic , Cooked tea leaves and Ash firewood) as anti-bacterial agents, were reported. All the results were obtained after 24 hours of microbial growing  .The ratio of doping with Peel the garlic , Cooked tea leaves and Ash firewood) was  1 to 17 W%. The size of egg shell foils used in this study was (< 400) μm. We compared the initial adhesion and growth of positive and negative gram bacteria . Bacteria brought from microbiology laboratory in Qurna general hospital   after insuring them by tests like Gram stain test ,Catalas test ,Manitol test, Urease test, H2S and Citrate tests  Coagulase test, Indol test,  Mthyl red  and Oxidase tests. The obtained results showed that the gram positive bacteria had a limited inhibition zone. Furthermore the obtained results were explained according to the bacterial cell wall  and it’s liquid contents.
