Abstract

Cadmium sulfide nanoparticles (CdS NPs) have many commercial applications in making dye-sensitized solar cells, light emitting diodes (LED) and nanobiosensors due to their unique properties. In this work, screening of aquatic bacterial strains for their ability in the green Extracellular synthesis of CdS NPs was studied. The prepared nanoparticles were examined using Optical emission and absorption spectroscopy analyses, Energy Dispersive X-Ray Spectroscopy (EDS) Scanning electron micrograph analysis and Fourier-transform infrared spectroscopy (FTIR). 32 cadmium-resistant aquatic strains were isolated by using enrichment. Among isolated strains, Pseudomonas pseudoalcaligenes is capable to synthesize CdS NPs. The extracellular nanoparticles produced by the strain Cd11 were investigated under optimal culture conditions. The results showed that culture supernatant of strain Cd11 treated with CdSO4 (3 mM) was able to catalyze the Extracellular synthesis of CdS NPs in the range of 12-19 nm with an average size of 15. 5 nm after 10 h of incubation at pH 8. 0 and temperature 35 ° C. To evaluate the Antibacterial activity of nanoparticles, agar well diffusion method was tested. Based on obtained results, CdS nanoparticles had an inhibitory effect against all tested microorganisms. Additionally, particles size distribution of CdS nanoparticles synthesized by culture supernatant of strain Cd11 had a good monodispersity and homogeneity for the specific applications.
