Description
Byline: Arjumand Shah Bano and Javed Iqbal Qazi - Email:qazi@scientist.com Abstract. Antagonistic activity of non-corrosive Bacillus isolates designated as SN-8 and SS-14 was evaluated against mild steel corrosion influencing, Bacillus cereus-SNB-4 and Bacillus coagulans-SS-5, respectively, by cross streak, disc diffusion and deep-well methods. Then corrosive bacteria were cultivated in cell-free cultural fluids of their respective antagonists supplemented with nutrient broth in the presence of mild steel coupons (MSC). After 90 days, corrosion rates of MSC exposed to B. cereus-SNB-4 and B. coagulans-SS-5 were found to be 39.5 and 37 mg.dm-2.d-1, respectively. When these bacteria were cultivated in the presence of cell free cultural fluids of their respective antagonists the corresponding values were found to be 9.53 and 9.44 mg.dm-2.d-1 as compared to the corresponding values of 24.99 and 22.2 mg.dm-2.d-1 of control (un-inoculated) MSC.
