“…4). In these biofilms, Bacteria, representing more than 98% of the microbial population estimated by qPCR, particularly Desulfovibrio species, detected as highly predominant on the basis of both bacterial 16S rRNA and dsrAB gene analyses, were likely the main culprits of MIC, as has been proposed previously (16,53,54). Desulfovibrio species are metabolically diverse and often versatile, coupling hydrogen or volatile fatty acid consumption with sulfate, iron, or nitrate reduction according to electron acceptor availability or alcohol fermentation in the absence of electron acceptors (55).…”

e Offshore oil production facilities are frequently victims of internal piping corrosion, potentially leading to human and environmental risks and significant economic losses. Microbially influenced corrosion (MIC) is believed to be an important factor in this major problem for the petroleum industry. However, knowledge of the microbial communities and metabolic processes leading to corrosion is still limited. Therefore, the microbial communities from three anaerobic biofilms recovered from the inside of a steel pipe exhibiting high corrosion rates, iron oxide deposits, and substantial amounts of sulfur, which are characteristic of MIC, were analyzed in detail. Bacterial and archaeal community structures were investigated by automated ribosomal intergenic spacer analysis, multigenic (16S rRNA and functional genes) high-throughput Illumina MiSeq sequencing, and quantitative PCR analysis. The microbial community analysis indicated that bacteria, particularly Desulfovibrio species, dominated the biofilm microbial communities. However, other bacteria, such as Pelobacter, Pseudomonas, and Geotoga, as well as various methanogenic archaea, previously detected in oil facilities were also detected. The microbial taxa and functional genes identified suggested that the biofilm communities harbored the potential for a number of different but complementary metabolic processes and that MIC in oil facilities likely involves a range of microbial metabolisms such as sulfate, iron, and elemental sulfur reduction. Furthermore, extreme corrosion leading to leakage and exposure of the biofilms to the external environment modify the microbial community structure by promoting the growth of aerobic hydrocarbon-degrading organisms.

“…Members of the family Rhodospirillaceae within the class Alphaproteobacteria were previously found in oil facilities and biofilms (15,68), and like Pseudomonas and Desulfovibrio species (18,53,69), these Alphaproteobacteria could contribute to biofilm formation by polysaccharide production, for example (Fig. 4) (68).…”

“…In most cases, studies deal with the effects of sulfate-reducing bacteria [6,9,11,12]. However, stimulation of the corrosion of metals, particularly steel, zinc, and galvanized steel [12,13] by other microorganisms (Esteria Coli, Proteus vulgaris, Pseudomonasaeruginosa, Brucella sp, Gallionella sp, Staphylococus aureus, Staphylococus epidermidis [7,13]) is considered as well.…”

Effect of the structure of o,o´-dihydroxyazo compounds on bactericidal and inhibitory ability

The paper is devoted to a study of the influence of the molecule structure of a number of o,o´-dihydroxyazo (DHA) compounds on their bactericidal ability toward sulfate-reducing bacteria (SRB) in the Postgate medium at small concentrations (5-20 mg/L). DHA compounds induce a decrease in number of bacterial cells, H 2 S production by SRB, and hydrogen permeation into carbon steel in the presence of SRB. The inhibition of steel corrosion in the bacterial medium by these substances is considered as well.

Microbial corrosion refers, by definition, to the degradation of materials due to the activity of a wide variety of microorganisms, usually embedded in a gel matrix—the biofilm—attached to the surface. The feature of MIC (microbial induced corrosion) is connected to three factors: microorganisms involved (bacteria, algae, moulds or fungi, individually or in combination), material, and environment (solution and conditions). In particular, degradation of metallic structures derives from the activity of a wide variety of microorganisms, either directly participating in electrochemical reactions on the metal surface or producing aggressive metabolites capable of making the environment corrosive. A wide range of microorganisms may be involved in corrosion processes, such as chemical attack of metals, concrete and other materials, by means of the by‐products of microbe metabolism, for example, sulfuric and carbonic acids, hydrogen sulfide or ammonia; attack of metal by a process in which the corrosion reaction is sustained by the combined action of microbes and metal or by a combination of bacteria; depassivation of metal surfaces and induction of corrosion cells; depolarization of cathodic reaction; microbial attack of organic materials (e.g., paint coatings, plastic linings), degradation of inhibitors, conversion of natural inorganic compound (e.g., sulfur). Remedial actions are similar to those taken to avoid corrosion, but must be applied much more rigorously, as once it starts, it is extremely difficult to stop MIC. Preventive actions include optimum design of the plant at the early stage and proper material selection based on expected operative and environmental conditions.
