The antimicrobial effects of Azadirachita indica crude leaves extract was investigated against Desulphovibrio species isolated from corroded water pipes in Minna, Niger State, Nigeria. Methanol and aqueous crude leaves extract of A. indica was prepared using cold maceration technique. Methanol crude extracts hindered corrosion of the metal in order of increasing concentration from 0.17 to 0.02%. Similarly, aqueous crude extract at 50 to 500 mg/ml inhibited corrosion of the metal from 0.15 to 0.02%. Phytochemical constituents of the crude extracts include saponins, anthraquinones, steroids, terpens, phenols, tannin, flavonoids, alkaloids and glycosides. Further investigations should be conducted to ascertain the chemical nature of the active compounds, including the minimal inhibitory and minimal bacteriocidal concentrations of the extracts.
Keywords: Antimicrobial, Azadirachta indica, corrosion, Desulphovibrio species.
