The effect of Desulfovibrio caledoniensis and Pseudomonas aeruginosa on the corrosion behaviour of 70Cu-30Ni alloy.
This work investigated the effect of Desulfovibrio caledoniensis (D. caledoniensis) and Pseudomonas aeruginosa (P. aeruginosa) on the microbiologically influenced corrosion (MIC) behaviour of 70Cu-30Ni alloy using surface analysis and electrochemical techniques. The results demonstrated that the mixed medium containing D. caledoniensis and P. aeruginosa further accelerated the MIC of 70Cu-30Ni alloy compared to the single species medium. The addition of exogenous pyocyanin (PYO) to the D. caledoniensis medium increased the maximum pit depth on 70Cu-30Ni alloy from 5.40 μm to 6.59 μm, and the corrosion current density (icorr) increased by one order of magnitude. From the perspective of bioenergetics and extracellular electron transfer (EET), the comprehensive MIC mechanism of 70Cu-30Ni alloy induced by D. caledoniensis and P. aeruginosa was proposed.
期刊介绍：
Biofouling is an international, peer-reviewed, multi-discliplinary journal which publishes original articles and mini-reviews and provides a forum for publication of pure and applied work on protein, microbial, fungal, plant and animal fouling and its control, as well as studies of all kinds on biofilms and bioadhesion.
Papers may be based on studies relating to characterisation, attachment, growth and control on any natural (living) or man-made surface in the freshwater, marine or aerial environments, including fouling, biofilms and bioadhesion in the medical, dental, and industrial context.
Specific areas of interest include antifouling technologies and coatings including transmission of invasive species, antimicrobial agents, biological interfaces, biomaterials, microbiologically influenced corrosion, membrane biofouling, food industry biofilms, biofilm based diseases and indwelling biomedical devices as substrata for fouling and biofilm growth, including papers based on clinically-relevant work using models that mimic the realistic environment in which they are intended to be used.
