This study aimed to demonstrates a positive correlation between silica metal tolerance ability of a drinking<br/>water fungi and its potential for the synthesis of silica oxide (SiO2) nanoparticles (NPs). Metal oxide NPs can be<br/>synthesized biologically by different methods including; microorganisms, plant extracts and\ or plant biomass.<br/>These methods in some time are better alternatives to the chemical and physical methods through an<br/>environmentally route. In the present work, twenty fungal strains were isolated from eight potable water samples<br/>and tested for producing silica nanoparticles (SiO2NPs), using precursor salt Dipotassium fluorosilicate (K2SiF6).<br/>Out of these twenty fungal strains, only one fungal isolate had the potency to reduce metal salt into metal NPs,<br/>which was identified by a molecular assay as Aspergillus tubingensis F20, and was assigned an Accession number<br/>of (MK226258.1) using the NCBI GenBank database. The factors affecting mono-dispersed production of SiO2<br/>NPs such as; reaction times, incubation temperatures, hydrogen ion concentrations (pH) and salt concentrations<br/>were optimized. It is revealed that 10-3 M precursor salt concentration, 72 h of reaction time at pH 3, and an<br/>incubation temperature 28°C are the optimum conditions for the production of smaller size NPs. The<br/>biosynthesized NPs was characterized using several techniques including; Dynamic light scattering (DLS),<br/>Transmission Electron Microscopy (TEM), Scanning Electron Microscopy (SEM), and Energy dispersive X-ray<br/>spectroscopy (EDX). It is observed that the shape of SiO2NPs is spherical with an average size of 8 nm, and<br/>surface charge of - 8.19 mv, which indicates that SiO2NPs is more stable<br/> |
