| Popis: | The fungus Aspergillus niger isolated from industrial area in Kirkuk city.was used to study its ability as reducing agent to prepare silver particals .The results showed that Ag NO3 solution 1mM changed in colour to brown ,which indicate the formation of silver nanoparticales. The spectrum of silver nanoparticles solution using Uvi,vis Spectroscopy was used as asecond step to confirm the production of nanoparticls ,Results showed that the absorbance at 430 nm also the X-ray diffraction showed peaks at 111,220,311 at the diffraction angles (31.77,46.11,57.21) respectively .The SEM images showed clear particales.delling with antibacterial activity the particles showed inhibitory effect against multi-antibiotic resistance Escherichia coli and Proteus mirabilis which found (33,33,32)mm and (35,35,34)mm respectively at the concentration 100% |
