A Novel Anti Nano-Silver Particle Bacteria

Nanoparticles have been widely used today, especially in the latest developed science materials. Silver nanoparticles, one of the most popular antimicrobial materials had been generally utilized in the textile industry and medical engineering. Different silver nanoparticles fabricating methods will make different physical or chemical property. Besides from silver nanofibers and plasma nanoparticles, most textile processing methods involve the dipping method. The entire industrial silver nanoparticles containing waste still has not any proper method to grip them out from the waste before it was drained into the environment. A novel Klebsiella sp. mutant was isolated from the ordinary laboratory analysis, and was revealed and identified as Klebsiella pneumonia by optical, biochemical and 16S rRNA sequence analysis, followed by NCBI genebank sequence blast result. This mutant strain (K pneumonia B50) could degrade 5 different trade mark silver nanoparticles, directly. Under the textile nanoparticles operation concentration (2%~10%), which exhibit a complete antimicrobial activity, all these five different kinds of commercial silver nanoparticles will be degraded into none antimicrobial activity by this mutant within 4 hours. Atomic absorbance analysis observed that the silver nanoparticles were absorbed or uptake by the cell directly. It means that, K pneumonia B50 could be served as a powerful bioremediation tool for industrial silver nanoparticles containing waste managing.
