In this paper, the inhibition effect by Tectona grandis Capped Fe-nanoparticle on the growth of Gram-negative and fungi strains of microbes (that are known to induce microbiologically-influenced-corrosion of metals) was investigated. For the study, two Gram-negative and two fungi strains of microbes were employed, with comparison of the inhibition performance by the Fe-nanoparticle material (for which leaf-extract from Tectona grandis was employed as precursor) with what obtained from use of an antibiotic chemical control. Results showed that while the Gram-negative and fungi strains of microbes for the study were resistant to the control antibiotic chemical, they all exhibited sensitivity to the biomaterial-based Fe-nanoparticle, which well inhibited their growth. The results from this paper therefore support recommendation on the usage of the Fe bio-synthesized nanoparticle for inhibiting microbiologically-influenced metallic corrosion in environments infested by the Gram-negative and fungi strains of microbes employed in this paper.
