Four thermophilic bacterial species, including the iron-reducing bacterium Geobacillus sp. G2and the sulfate-reducing bacterium Desulfotomaculum sp. SRB-M, were employed to integrate abacterial consortium. A second consortium was integrated with the same bacteria, except forGeobacillus sp. G2. Carbon steel coupons were subjected to batch cultures of both consortia.
The corrosion induced by the complete consortium was 10 times higher than that induced bythe second consortium, and the ferrous ion concentration was consistently higher in ironreducingconsortia. Scanning electronic microscopy analysis of the carbon steel surfaceshowed mineral films colonized by bacteria. The complete consortium caused profusefracturing of the mineral film, whereas the non-iron-reducing consortium did not generatefractures. These data show that the iron-reducing activity of Geobacillus sp. G2 promotesfracturing of mineral films, thereby increasing steel corrosion.
