Effect of Multispecies Microbial Consortia on Microbially Influenced Corrosion of Carbon Steel

Microbially influenced corrosion (MIC) is responsible for significant damage to major marine infrastructure worldwide. While the microbes MIC typically exist in environment a synergistic combination of different species, vast majority laboratory-based experiments are performed with single microbial pure cultures. In this work, grade steel was exposed sulfate reducing bacterium (SRB, Desulfovibrio desulfuricans) and various combinations bacteria (both cultures mixed communities), studied. Differences biofilm composition succession, weight loss pitting attack were observed test configurations The reduction phenotype successfully shown half-strength broth both communities. highest according pitting, recorded tests D. desulfuricans alone when incubated nominally aerobic environment. multispecies consortia yielded lower general rates compared or uninoculated control.
