(A and B) Anaerobic corrosion rates in biocorrosion reactors filled with WP-EAS medium as a function of time. The reactors were inoculated with D. vulgaris wild-type (WT) or mutant strains, as indicated. The iron coupon working electrodes had a set EWE value of −1.1 V. Corrosion rates are reported for an EWE (Ecorr) value of −0.7 V. (C and D) Concentrations of sulfate and sulfide as a function of time.
