The Inhibitive Effect of Gmelina arborea Fruit Extract on Biocorrosion Induced by Sulphate-reducing Bacteria

Microbial activities contribute significantly to the global economic burden of corrosion. The sulphatereducing bacteria (SRB) are major cause of biocorrosion in anoxic environments. This study investigated the corrosion inhibition efficiency of Gmelina arborea extracts against corrosion of carbon steel caused by SRB isolated from injection and produced water from Bonga oilfield. The SRB isolation, antimicrobial assay and corrosion experiments were carried out in a Coy anaerobic chamber.
