Abstract
Effect of Incubation Time, CuSO4 and Glucose Concentrations on Biosynthesis of Copper Oxide (CuO) Nanoparticles with Rectangular Shape and Antibacterial Activity: Taguchi Method Approach
Highlights
Nanoparticles (NPs) are particles with a diameter size in the range of 1 to 100 nm (≤0.1 μm) and unique properties that mainly depend on their size [1, 2]
Bacterial strains were incubated for reduction of copper ions to cupric oxide NPs (CuO NPs); there was rapid reaction
Suspension of CuO NPs by minimum bactericidal concentrations ranging from 100 μg/mL to 5000 μg/mL illustrated antibacterial activity against S. aureus and E. coli [59]
Summary
Nanoparticles (NPs) are particles with a diameter size in the range of 1 to 100 nm (≤0.1 μm) and unique properties that mainly depend on their size [1, 2]. We used selected strain Halomonas elongata IBRC-M 10214 to reduce Cu2+ ion to pure Cu NPs and evaluated the effect of three factors (CuSO4, glucose, NaCl concentrations) on the biosynthesis of Cu NPs. In the present study, in addition to synthesis of CuO NPs, we used incubation time (48, 72 and 96 h) as different influencing factors in this process.
