“…The, observed corrosion was attributed to activity of D. vietnamensis, the dominant SRB species on the metallic surface. Pitonzo et al [29] investigated the corrosion induced by various bacterial species isolated from the deep subsurface at Yucca mountain. The maximum corrosion rates observed with iron-oxidizing, sulphatereducing and exopolysaccharide (EPS)-producing bacteria were 0.06, 0.08 and 0.07 mm year À1 , respectively.…”

Representative microbial cultures from an oil reservoir and electrochemical techniques including potentiodynamic scan and linear polarization were used to investigate the time dependent corrosion rate associated with control of biogenic sulphide production through addition of nitrite, nitrate and a combination of nitrate-reducing, sulphide-oxidizing bacteria (NR-SOB) and nitrate. The addition of nitrate alone did not prevent the biogenic production of sulphide but the produced sulphide was eventually oxidized and removed from the system. The addition of nitrate and NR-SOB had a similar effect on oxidation and removal of sulphide present in the system. However, as the addition of nitrate and NR-SOB was performed towards the end of sulphide production phase, the assessment of immediate impact was not possible. The addition of nitrite inhibited the biogenic production of sulphide immediately and led to removal of sulphide through nitrite mediated chemical oxidation of sulphide. The real time corrosion rate measurement revealed that in all three cases an acceleration in the corrosion rate occurred during the oxidation and removal of sulphide. Amendments of nitrate and NR-SOB or nitrate alone both gave rise to localized corrosion in the form of pits, with the maximum observed corrosion rates of 0.72 and 1.4 mm year(-1), respectively. The addition of nitrite also accelerated the corrosion rate but the maximum corrosion rate observed following nitrite addition was 0.3 mm year(-1). Furthermore, in the presence of nitrite the extent of pitting was not as high as those observed with other control methods.

“…Although MIC is also problematic in freshwater and terrestrial soil environments (12,(18)(19)(20)(21), knowledge on MIC-inducible freshwater microorganisms has been limited. In addition to methanogens, microorganisms that conserve energy through acetogenesis (equation 6) have been proposed to engage in EMIC in freshwater environments (22):…”

cCorrosion of iron occurring under anoxic conditions, which is termed microbiologically influenced corrosion (MIC) or biocorrosion, is mostly caused by microbial activities. Microbial activity that enhances corrosion via uptake of electrons from metallic iron [Fe(0)] has been regarded as one of the major causative factors. In addition to sulfate-reducing bacteria and methanogenic archaea in marine environments, acetogenic bacteria in freshwater environments have recently been suggested to cause MIC under anoxic conditions. However, no microorganisms that perform acetogenesis-dependent MIC have been isolated or had their MIC-inducing mechanisms characterized. Here, we enriched and isolated acetogenic bacteria that induce iron corrosion by utilizing Fe(0) as the sole electron donor under freshwater, sulfate-free, and anoxic conditions. The enriched communities produced significantly larger amounts of Fe(II) than the abiotic controls and produced acetate coupled with Fe(0) oxidation prior to CH 4 production. Microbial community analysis revealed that Sporomusa sp. and Desulfovibrio sp. dominated in the enrichments. Strain GT1, which is closely related to the acetogen Sporomusa sphaeroides, was eventually isolated from the enrichment. Strain GT1 grew acetogenetically with Fe(0) as the sole electron donor and enhanced iron corrosion, which is the first demonstration of MIC mediated by a pure culture of an acetogen. Other well-known acetogenic bacteria, including Sporomusa ovata and Acetobacterium spp., did not grow well on Fe(0). These results indicate that very few species of acetogens have specific mechanisms to efficiently utilize cathodic electrons derived from Fe(0) oxidation and induce iron corrosion. where ϩ0.82 V and Ϫ0.41 V reference the SHE.The cathodic hydrogen evolution on iron surfaces is usually a particularly slow reaction under neutral pH conditions, because proton availability is limited and the reaction has low electrode potential and high overpotential. Hence, theoretically, iron corrosion in anoxic environments should not be a serious problem. However, iron corrosion in anoxic environments has been reported often and, in most cases, it is thought to be mediated by metabolic activities of microorganisms therein (1-3). Iron corrosion that occurs in this manner is termed microbiologically influenced corrosion (MIC) or biocorrosion. Diverse kinds of microorganisms, including sulfate-reducing bacteria (SRB), Fe(II) oxidizers, Fe(III) reducers, fermenting bacteria, and methanogens, have been reported as contributing to MIC (4-9). These microorganisms induce MIC in a number of ways, including formation of redox/chemical gradient on the iron surfaces, production of corrosive chemicals (e.g., H 2 S and organic acids), degradation of protective coatings on iron surfaces, and acceleration of cathodic reactions (10).Among such diverse MIC mechanisms, acceleration of cathodic reactions, often referred to as cathodic depolarization, was first proposed in the 1930s and has been considered one of the most promine...

A strong attention is recently paid to surface properties of building materials as these allows controlling solar gains of the building envelope and overheating of buildings and urban areas. In this regard, deterioration phenomena due to biological aggression can quickly damage solar-reflecting roof surfaces and thus increase sharply solar gains, discomfort, air-conditioning costs and waterproofing degradation. The same deterioration problem has deleterious effect on cultural heritage, ruining its huge historic and artistic value. This work is aimed at providing an overview on the different organisms that affect the surface of most used building materials, to support the design of new building materials with long-lasting surface properties and to find a way to preserve cultural heritage. Artificial ageing is the long-term aim of this investigation, in which what in nature happens after months or years is compressed in a very short time by forcing the growth of microorganisms through a strict control on the different conditioning factors. Both natural and artificial ageing are eventually outlined in the last part of this work to provide a comprehensive idea of what is necessary to study in a complete way biological ageing protocols on building materials. Several characterization techniques are also introduced to analyse the influence of microorganisms on the surface of different building materials.
