“…Currently, the negative aspects of the interaction between metallic objects and microbes have been highlighted in scientific research. Several studies have examined microbiologically induced corrosion of industrial materials such as steel (50)(51)(52)(53). Indeed, the development of bacterial biofilms on the surface of such objects induces changes in the electrochemical conditions (50), which leads to the formation of corrosion layers and produces structural damage to the metal core.…”

Iron artifacts are common among the findings of archaeological excavations. The corrosion layer formed on these objects requires stabilization after their recovery, without which the destruction of the item due to physicochemical damage is likely. Current technologies for stabilizing the corrosion layer are lengthy and generate hazardous waste products. Therefore, there is a pressing need for an alternative method for stabilizing the corrosion layer on iron objects. The aim of this study was to evaluate an alternative conservation-restoration method using bacteria. For this, anaerobic iron reduction leading to the formation of stable iron minerals in the presence of chlorine was investigated for two strains of Desulfitobacterium hafniense (strains TCE1 and LBE). Iron reduction was observed for soluble Fe(III) phases as well as for akaganeite, the most troublesome iron compound in the corrosion layer of archaeological iron objects. In terms of biogenic mineral production, differential efficiencies were observed in assays performed on corroded iron coupons. Strain TCE1 produced a homogeneous layer of vivianite covering 80% of the corroded surface, while on the coupons treated with strain LBE, only 10% of the surface was covered by the same mineral. Finally, an attempt to reduce iron on archaeological objects was performed with strain TCE1, which led to the formation of both biogenic vivianite and magnetite on the surface of the artifacts. These results demonstrate the potential of this biological treatment for stabilizing archaeological iron as a promising alternative to traditional conservation-restoration methods.IMPORTANCE Since the Iron Age, iron has been a fundamental material for the building of objects used in everyday life. However, due to its reactivity, iron can be easily corroded, and the physical stability of the object built is at risk. This is particularly true for archaeological objects on which a potentially unstable corrosion layer is formed during the time the object is buried. After excavation, changes in environmental conditions (e.g., higher oxygen concentration or lower humidity) alter the stability of the corrosion layer and can lead to the total destruction of the object. In this study, we demonstrate the feasibility of an innovative treatment based on bacterial iron reduction and biogenic mineral formation to stabilize the corrosion layer and protect these objects.KEYWORDS akaganeite, biogenic minerals, Desulfitobacterium, vivianite, iron reduction I ron artifacts are among the most recurring items in archaeological findings. When buried, these objects develop a complex corrosion layer, the composition of which depends on the environmental conditions of the burial site (i.e., oxygen, humidity, salinity, pH, and presence of microorganisms).

“…vulgaris incubator for 9 days were used. The retrieved coupon whose surface is covered with biofilm was immersed in 2.5 wt% glutaraldehyde for 8 h and subsequently washed with a graded series (30%, 50%, 70%, 100% v/v) of ethanol for dehydration 34, 37 , and finally stored in a desiccator and later used for SEM and EDX analyses. The SEM images with simultaneous elemental characterization using EDX were obtained using FEI Quanta FEG 250 Environmental Scanning electron microscope (ESEM) under an acceleration voltage of 15 kV in high vacuum.…”

Five selected carbazole derivatives, namely carbazole, 3,6-dibromocarbazole, 2-hydroxycarbazole, 1,2,3,4-tetrahydrocarbazole and 9-(2-ethylhexyl)carbazole-3,6-dicarboxaldehyde were investigated for their inhibitive effects on Desulfovibrio vulgaris (D. vulgaris) induced corrosion of mild steel and in 1 M HCl medium using weight loss, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) techniques. The carbazole derivatives were found to be mixed type inhibitors with predominantly cathodic inhibitive effects for mild steel in 1 M HCl. Surface morphology results showed the compounds formed adsorbed film on mild steel surface in both aqueous acid and sulphate reducing bacteria (SRB) media. Quantum chemical calculations were used to provide molecular based explanations for the inhibitive effects of the compounds. The interactions of the molecules with mild steel surface was simulated based on molecular dynamic simulations approach using Fe(110) crystal surface as representative metallic surface.

“…Some SRB bacteria can use both elemental sulfur and sulfate as electron acceptors. Common SRB include the genera Desulfovibrionales, Desulfosporosinus, Desulfotomaculum, Syntrophobacterales, Desulfosporomusa, and Desulfobacterales [16,17]. Thermodesulfovibrio sulfate-reducing species are also found as a member of the Nitrospirae phylum.…”

Hungary s0010 8.1 Introduction p0010 Microbiologically influenced corrosion (MIC) has received increasing attention by engineers and scientists from different fields (materials and corrosion scientists and engineers, biologists, and microbiologists). MIC refers to the possibility that microorganisms are involved in the deterioration of metallic (and nonmetallic) materials. Microbial corrosion is a significant problem affecting the oil and gas and other industries. It degrades the integrity, safety, and reliability of pipeline operations and other systems. However, the mere presence of given classes of microbes associated with MIC does not indicate that MIC is occurring. Nor does showing that the presence of a given type of microorganisms establishes a cause-and-effect relationship between the bacteria and metal dissolution. For MIC to occur, water presence, even at very low amounts, is necessary [1e4]. p0015The last decade revealed that not only the sulfate-reducing bacteria (SRB) are responsible for MIC but also several other microbes, e.g., the acid producers, iron oxidizers, and general aerobic bacteria [1]. MIC is rarely associated with one single mechanism or one single species of microorganisms. In addition to SRB many microorganisms occurring in natural environments are also considered corrosion-causing microbes, including methanogens, sulfur-oxidizing bacteria (SOB), acid-producing bacteria (APB), ironoxidizing bacteria (IOB), iron-reducing bacteria (IRB), and manganese-oxidizing bacteria (MOB). Each of these physiological groups of microorganisms may contain hundreds of individual species. Each group of bacteria or an individual species of bacteria alone can influence metal corrosion; however, severe MIC in a natural environment is always caused by microbial communities containing many different types of microbes. p0020For better understanding of MIC and its threats on pipelines and other structures, it is essential to learn more about how microbes influence metallic corrosion, to identify their presence and existence, and to monitor their destructive activities. MIC is not a new type of corrosion, but it involves microorganisms that, by their presence and active, aggressive metabolites and exopolymeric substances (EPS) (produced by microorganisms and composed mainly of polysaccharides) degrade materials, especially metals. The metabolic products (e.g., sulfide, organic acids) alter the interface chemistry resulting in increased corrosion rate and, together with the EPS, on the metal surface cause pH and dissolved oxygen gradients that lead first to localized (pitting and crevice) corrosion, which if remains unmitigated, will lead to metal wall perforations [4e6].Trends in Oil and Gas Corrosion Research and Technologies. http://dx. AbstractMicrobiologically influenced corrosion (MIC) refers to the influence of microorganisms on the kinetics of corrosion processes of metals and nonmetallic materials, caused by adhering to the interfaces (usually referred to as "biofilms").
