Abstract

Fungus of MucorindicusCBS 226.29 ET, in this study was used to synthesize gold nanoparticles (AuNPs). Synthesis of nanoparticles by microorganisms may offer an environmentally friendly and affordable alternative to traditional physical and chemical methods. The microbial synthesis of nanoparticles is an approach based on green chemistry which mutually connects microbial biotechnology and nanotechnology. A surface level plasmon resonance peak was observed at 500 nm by UV-bis spectra of AuNPs. Images of AuNP via transmission electron microscope exhibited various shapes and dispersibility characteristics. The synthesis of AuNPs were optimum at the conditions 1.5 mM/L of HAuCl4, 0.6 g biomass and pH range 7-11. The decolorization of different azo dyes was catalyzed efficiently with the bio-AuNPs and a new microbial resource candidate was thus demonstrated for these AuNPs through green synthesis, along with a potential bio-AuNP application for decolorization of azo dyes.
