| Abstract: | Naturally occurring biogenic molecules are of considerable interest because of increased attention on the development of environmentally compatible, non-polluting corrosion inhibitors. In the present work mild steel was exposed to culture containing free cells, coated and calcium alginate immobilized P. fluorescens. The corrosion resistance in the presence of immobilized P. fluorences was measured by corrosion potential, potentiodynamic polarizati on and weight loss techniques. Inhibition of mild steel in the iron deficient culture medium of P. fluorences was attributed to the production of siderophores such as enterobactin, parabactin, aerobactin, rhodobactin and ferrichrome which act as chelation agents and become chemisorbed onto the surface of mild steel. |
