The performance of Hura crepitans mediated Ag (silver) nanoparticle material on the inhibition of microbes (including six bacteria and a fungus strain) inducing microbiologically-influenced-corrosion (MIC) of metals was investigated in this paper. Leaf-extract was obtained from the Hura crepitans for use as a precursor for the Ag-nanoparticle synthesis, which was then characterised by the instrumentation of scanning electron microscopy and energy dispersive spectroscopy (SEM+EDS). The natural plant-mediated Ag-nanoparticle material was then utilised for sensitivity and/or resistance experimental investigations against three Gram-positive and three Gram-negative bacteria and a fungus strains of microbes that are known to induce microbiologically-influenced-corrosion in metallic materials. From this, the inhibition of microbial growth by the plant-extract mediated Ag-nanoparticle was compared with that from a commercial antibiotic that was used as the control. From the results, it was established that all the microbial strains studied were sensitive to the Hura crepitans mediated Ag-nanoparticle material while three out of the seven microbial strains for the study were resistant to the control antibiotic chemical. The implications and recommendations, ensuing from these results, on the use of the bio-mediated Ag-nanoparticle in MIC mitigation/control applications are detailed in the study.

Key words: Hura crepitans leaf-extract, bio-mediated Ag-nanoparticle, control of MIC inducing microbes, bio-material characterization
