“…Various earlier attempts to achieve corrosion protection by growing aerobic biofilms on steel have not yielded vivianite (Thomas et al, 1988;Pedersen & Hermansson, 1989;1991;Jack et al, 1992;Hernandez et al, 1994;Jayaraman et al, 1997a). It seems that the phosphate concentrations, which were generally below 2 mM, were simply insufficient.…”

Mild steel coupons were incubated in cultures of three different aerobic bacteria, viz. Rhodococcus sp. C125, Pseudomonas pulida mt2 and Streptomyces pilosus DSM 40714 and then exposed to a corrosive aqueous medium. A significant reduction in the corrosion rate was observed in a corrosive medium when the steel had been incubated in mineral media containing more than 2 mM phosphate with growing, biofilm-forming bacteria which had direct access to the steel surface, but not with the non biofilm-forming S. pilosus DSM 40714. Rhodococcus sp. C125 and P. putida mt2 induced a surface reaction, resulting in the formation of vivianite. This barely insoluble iron(II)-phosphate was found to be the cause of the corrosion inhibition. The surface reaction was always accompanied by an increase in the iron concentration in the medium. In contrast to biocorrosion processes known so far, iron release stopped after some days. The results suggest that bacterial activity may induce the inhibition of corrosion of mild steel.

“…Sulfuric acid is especially dangerous since it can retain a considerable amount of crystal water. The presence of such large molecules in pores of a material makes its structure degrade [17]. According to conventional concepts, microbiological corrosion can follow different pathways:…”

“…Sulfides promote the corrosion attack of the well equipment, discharge and gathering pipelines, and units of the oil treating system and the system maintaining the oil-pool pressure (MOPP). Provided the conditions are favorable, SRB continue to live in ground service lines, oil-field apparatuses, pipes, and tanks under the precipitates of paraffin, corrosion products, and thickened oil [14][15][16][17][18][19][20]. Biocorrosion in watercollecting systems can be represented as a closed cycle (Fig.…”

“…One hypothesis is that anoxic niches, which are often present within heterotrophic biofilms, may be needed for SRB to be active. Other biofilms, in contrast may have a protective effect on material surfaces, for instance, by inducing the formation of specific iron phosphate minerals (Hernandez et al, 1994;Volkland et al, 2000a;2000b).…”

The ability of the SRB Desulfovibrio desulfuricans to colonize aerobic heterotrophic or nitrifying biofilms on stainless steel surfaces was investigated by fluorescence in situ hybridization (FISH) in combination with confocal laser scanning microscopy (CLSM), the polymerase chain reaction (PCR) directed to the dissimilatory sulfite reductase and by oxygen microelectrodes. Biofilms of heterotrophic bacteria and of nitrifying bacteria pregrown on steel coupons in laboratory devices were not invaded by cells of D. desulfuricans within 1 week, even though large pores as possible entry paths and anoxic zones and sulfate in the medium as prerequisites for activity of D. desulfuricans existed in the biofilms. On the contrary, coinoculation of D. desulfuricans and aerobic heterotrophic bacteria from water of a cooling water system led to immediate establishment of a small but detectable population of D. desulfuricans distributed over the whole biofilm depth. The fact that individual SRB attached efficiently and irreversibly to steel suggests that in coinoculation experiments, establishment of SRB in the biofilm possibly occurred from the biofilm base, which is the zone that became anoxic first. Based on these findings it is suggested that the idea of protecting surfaces from SRB-induced corrosion by pregrowing and maintaining specific bacterial biofilms should be further pursued.
