Characterization of silver nanoparticles produced by Streptomycesspp. isolated from soil samples

الملخص EN

(24) soil samples were collected from Hilla city.

Ten Actinomyctes were isolated.

Four Streptomycesspp.

isolate were diagnosed.

Theses isolates were examined for production of sliver nanoparticle.

Streptomyces spp.2 isolate were able on sliver nanoparticle production.

All Streptomyces spp.

isolates having Aerial Mycelium grey in color and Yellow-green Substrate Mycelium.

Streptomyces spp.2 was selected for study characterization of sliver nanoparticle production.

These isolate was grey aerial mycelium and yellow-brown substrate mycelium, glucose and sucrose using ,negative for mannitol and mannose.

The characteristics of sliver nanoparticle was studied.

The UV spectrum showed maximum absorption(λ max) at 422 nm.

The FT-IR spectrum analysis for AgNPs represented absorption peak at 3402 cm-1 which refer to OH group,3080 cm-1 refer for C-H aromatic group,2924 indicate for presence of C-H aliphatic group,1749,1724 cm-1 indicate to C=O group (carbonyl group), 1651 indicate to presence C=C group,1375 indicate to presence of C-O-C, 794 indicate to presence C-Cl or C-Br.

Biosynthesized AgNPs are spherical in shape with size (78.96 nm ) and having purity (75.09%)as examined by EDXA combined with FE-SEM.
