“…Members of the Desulfobacteraceae account for a significant portion of the active microbial community in biofilms of subsurface mine drainage systems (Labrenz & Banfield, 2004). Formation of lactateutilizing D. alaskensis biofilms has been correlated with hotspots of iron corrosion (Wikiel, Datsenko, Vera, & Sand, 2014). Integrated transcriptomic and proteomic analyses of lactate-fed biofilms of D. vulgaris displayed major changes in the energy metabolism and excretion of specific extracellular proteins, as compared to planktonic control cultures (Clark et al, 2012).…”

“…It was once reported that the high content of N was conducive to bacterial adhesion and reproduction [15]. In a marine environment, due to the existence of a diverse variety of microbes, marine biofilms often quickly developed on an exposed metal surface leading to a high risk of MIC [16], which can result in costly damages in many industries [17]. Previous studies have attributed localized corrosion initiation and pitting corrosion to biofilm formation.…”

“…A first evaluation of the suitability of EPS produced by several bacterial strains, including sulphate-reducing bacteria (SRB) and Pseudomonas, for corrosion protection of metallic substrates (pure iron, carbon steel and 304 stainless steel) confirmed that some of them might possess candidate compounds to be potentially used for a further development of green corrosion mitigation strategies [24]. Recently, the role of Desulfovibrio alaskensis EPS in the biocorrosion initiation or inhibition of carbon steel in marine environment was studied [25,26].…”

Copper alloys, often used in cooling circuits of industrial plants using seawater as coolant, can be affected by biocorrosion induced by biofilm formation. Extracellular polymeric substances (EPS) produced by bacteria play a fundamental role in the different stages of biofilm formation, maturation and maintenance. The influence of loosely bound (LB) and tightly bound (TB) EPS, extracted from marine Pseudomonas NCIMB 2021, on the electrochemical behaviour of 70Cu-30Ni (wt. %) alloy in static artificial seawater (ASW) and on the chemical composition of oxide layers was studied by combined electrochemical measurements (polarisation curves, EIS) and surface analysis (XPS, ToF-SIMS). Results were compared with those obtained in the presence of bovine serum albumin (BSA), a model protein.Compared to 70Cu-30Ni alloy in static ASW without biomolecules, for which a thick duplex oxide layer (outer redeposited Cu 2 O layer and inner oxidized nickel layer) is shown, the presence of BSA, TB EPS and LB EPS leads to a mixed oxide layer (oxidized copper and nickel) with a lower thickness. In the biomolecules-containing solutions, this oxide layer is covered by an adsorbed organic layer, mainly composed of proteins. A model is proposed to analyse impedance data obtained at the corrosion potential. The fitting procedure of impedance diagrams allows extracting the anodic charge transfer resistance, from which the corrosion current density can be calculated. The results show a slow-down of the anodic reaction in the presence of biomolecules (BSA, TB EPS and LB EPS), and a corrosion inhibition effect by LB EPS and to a lesser extent by BSA. No detrimental effect is evidenced with TB EPS.
