Abstract

The development of reliable processes for the synthesis of silver nanomaterials is an important aspect of nanotechnology today. There are few reports in literature on the biosynthesis of silver NANOPARTICLEs using microorganisms such as fungi. Here in this study, the production of silver NANOPARTICLEs by some microorganisms was investigated. The test strains were cultivated in their special conventional conditions for 24 hours. Silver nitrate at concentration of 10-3 M was separately added to the each reaction vessels that were contained the supernatants of Klebsiella pneumoniae, Escherichia coli, Enterobacter cloacae, Staphylococcus aureus, Bacillus subtilis, Lactobacillus acidophilus and Candidaalbicans. The silver NANOPARTICLEs were characterized by scanning electron microscopy and DV-visible spectroscopy. The silver NANOPARTICLEs were effectively produced, by Klebsiella pneumoniae, Escherichia coli and Enterobacter cloacae. We did not observe any EXTRACELLULAR biosynthesis activity from other microorganisms such as the Staphylococcus aureus, Bacillus subtilis, Lactobacillus acidophilus and Candida albicans in conditions tested during this investigation, this is the first report on the production of silver NANOPARTICLEs in enterobacteriaceae.
