Biosynthesized Silver Nanoparticles (AgNPs): Melanoidin Decolorization in the Bacterial Extracellular Supernatant
Author(s): Kian David*
The goal of the current study was to use biosynthesized silver nanoparticles (AgNPs) to decolorize synthetic melanoidins using bacterial extract in an immobilized state. Bacillus sp. BAC1 was used to biosynthesize silver nanoparticles employing an extracellular approach. UV-Visible spectroscopic spectroscopy was used to analyze silver nanoparticles of brown hue that were produced through biosynthesis. The spherical shape and smooth surface morphology of the nanoparticles were further characterized using Transmission electron microscopy (TEM), Scanning electron microscopy (SEM), Energy dispersive X-ray spectroscopy (EDX), Fourier transform infrared spectroscopy (FT-IR), and Atomic force microscopic (AFM) analysis. Under typical circumstances, the amount of melanoidin decolorization in the bacterial extracellular supernatant was greater than 65% (in 12 hours). In comparison,.. View More»
