Description
In this paper, the minimum inhibition concentration of Dialium guineense (D. guineense) mediated Zn-nanoparticle material on Gram-positive strains of microbes inducing microbiologically-influenced-corrosion (MIC) of metals, were experimentally studied and with the experimental data subjected to numerical analyses. Four strains of Gram-positive strains of microbes that are known to induce MIC on metallic materials were employed in seeded agar plates and against which different concentrations of Zn-nanoparticle (having D. guineense leaf-extract as precursor) were dispersed. Growth inhibition measurements of the Gram-positive microbial strains were then analyzed via mathematical correlation modeling, analyses of variance and Newton-Raphson methodology for improving details of minimum inhibition concentration of the bio-synthesized Zn-nanoparticle material against the microbial strains. Results from the study are of importance for responsible applications of MIC controlling, and for avoiding inadvertent MIC aggravating, system.
