Abstract Electrochemical polarization curves, Atom Force Spectroscopy and Electronic Probe Measurement Analysis were used to study the sensitivity of biofilm on Q235 steel to MDOPD in the culture medium inoculated sulfide-reducing bacteria (SRB). The experiment results show that surface status of Q235 steel electrode and corrosion reaction facilitated by SRB were decreased greatly owing to the adsorptive film of MDOPD. It is difficult for metabolized product of SRB in medium and corrosion production to deposit directly on carbon steel surface, then the acceleration effect of SRB medium and course including acid soak to corrosion was reduced markedly.At the same time, it is hardly possible for SRB in medium to metabolize on carbon steel surface and this would decrease the possibility for SRB to assist corrosion in the medium.
