Characterization of ZnO nanoparticles produced by Streptomyces spp. isolated from Iraqi soil samples

Thirty two soil samples were collected from Hilla city, Babylon Province, Iraq. Ten isolates of Actinomyctes were isolated. Four Streptomyces spp. isolate were diagnosed, and all of its were gram positive, grey aerial mycelium and yellowish- green substrate mycelium after culturing on Yeast-Malt extract medium. All Streptomyces spp. isolates screened for production Zno nanoparticles. Streptomyces spp.4 was able for producing of nanoparticle. Ultra violet (UV) spectrum for ZnO particles showed that maximum absorption at 404 nm. FT-IR spectrum of Zno nanoparticles represented absorption peak at 3319.49 cm-1 indicate to produce presence of O-H group. While 2245.14 cm-1 indicate to produce presence of CΞC. Results of 1670.35 cm-1 indicate to C=C group, 1614.42 cm-1 refered to C=O group. As well as,1101.35 cm-1 indicated to C-O bending, 983.70 cm-1 indicated to C-O stretching,744.52 cm-1 indication to C-H, and 613.36 cm-1 indicate to C-X stretching. The SEM for Zno particles showed that its a spherical in shape and size range (60.40-67.04) nm. EDXA spectrum detected a strong signal for Zn with purity 42%.
