Description
Summary:This study demonstrated that, myco-synthesis of zinc oxide nanoparticles (ZnONPs) using the aqueous extract of button mushroom ( Agarius bisporus ) as a reducing agent. The nanoparticle formation was evaluated by UV–visible spectroscopy, Fourier Transform-Infrared spectroscopy, X-ray Diffraction spectroscopy, Energy Dispersive X-ray spectroscopy, and Transmission Electron Microscopy. Anti-corrosion against copper metal was studied in the occurrence of a highly corrosive aerobic bacterium B. thuringiensis EN2, Terribacillus aidingensis EN3, and Bacillus oleronius EN respectively. The results reveal that mixed consortium forms a thick biofilm on the metal surface and the weight loss (WL) was significantly increased to 0.041 ± 2 g when compared to abiotic system (0.014 ± 1 g). In contrast, inhibitor system WL was reduced about 0.004 ± 1 g than biotic system. For further confirmation of the above results, Surface analysis and EIS result revealed that the ZnONPs has inhibited the corrosive bacterial biofilm. This is the first description disclosing the application of myco-synthesized ZnONPs as effective anti-corrosive inhibitors against microbial influenced corrosion.
