“…Also, there is an increase in contradictory reports on both accelerating and inhibiting actions on the corrosion process of the same functional group of microorganisms, such as sulfate reducers (Enning et al, 2012;Venzlaff et al, 2013), iron reducers (AlAbbas et al, 2013) and methanogens (Uchiyama et al, 2010). These studies show a strong species specificity for either MIC or MICI, which indicates that there is an urgent need to focus on the mechanisms rather than on the presence of certain functional groups, which is common practice at the moment.…”

The dual role of microbes in corrosion

2014

Corrosion is the result of a series of chemical, physical and (micro) biological processes leading to the deterioration of materials such as steel and stone. It is a world-wide problem with great societal and economic consequences. Current corrosion control strategies based on chemically produced products are under increasing pressure of stringent environmental regulations. Furthermore, they are rather inefficient. Therefore, there is an urgent need for environmentally friendly and sustainable corrosion control strategies. The mechanisms of microbially influenced corrosion and microbially influenced corrosion inhibition are not completely understood, because they cannot be linked to a single biochemical reaction or specific microbial species or groups. Corrosion is influenced by the complex processes of different microorganisms performing different electrochemical reactions and secreting proteins and metabolites that can have secondary effects. Information on the identity and role of microbial communities that are related to corrosion and corrosion inhibition in different materials and in different environments is scarce. As some microorganisms are able to both cause and inhibit corrosion, we pay particular interest to their potential role as corrosion-controlling agents. We show interesting interfaces in which scientists from different disciplines such as microbiology, engineering and art conservation can collaborate to find solutions to the problems caused by corrosion.

“…Recently, two different mechanisms of iron corrosion were described, that is, chemical MIC (CMIC) and electrical MIC (EMIC) (Enning et al, 2012;Enning and Garrelfs, 2013;Venzlaff et al, 2013). These two mechanisms differ in the source of electrons used by the SRB, which was shown to be species specific.…”

“…More frequently, the stimulating effect of bacteria cells, in particular SRB, is interpreted as the result of acceleration of the cathodic reaction because of accumulation of micro organism vital activity products, primarily hydrogen sulfide [5,16]. However, the possibility of substantial change in the nature of electrochemical reactions [9] and electron transfer in the electrode processes [11] is sufficiently broadly discussed. Serious attention is paid to studies of biofilm formation processes based on micro organism colonies and their screening influence [10] or accumulation of corrosion stimulators near a corroding surface [17].…”

“…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.…”

“…The adverse effect of microbiological corrosion on structural metals is so great [1] and their damage to the world economy is so huge [2] that the problems of struggle against it are constantly in the field of vision of the researches [3][4][5][6][7][8][9][10][11][12][13][14][15]. Moreover, 20% of all losses from corrosion are due to microbiological impact.…”

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

2017

Int. J. Corros. Scale Inhib.

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.

Biogenic Iron Sulfide Nanoparticles to Enable Extracellular Electron Uptake in Sulfate‐Reducing Bacteria

et al. 2020

Microbes synthesize cell‐associated nanoparticles (NPs) and utilize their physicochemical properties to produce energy under unfavorable metabolic conditions. Iron sulfide (FeS) NPs are ubiquitous and are predominantly biosynthesized by sulfate‐reducing bacteria (SRB). However, the biological role of FeS NPs in SRB remains understudied. Now, conductive FeS NPs function is demonstrated as an electron conduit enabling Desulfovibrio vulgaris Hildenborough, an SRB strain, to utilize solid‐state electron donors via direct electron uptake. After forming FeS NPs on the cell surface, D. vulgaris initiated current generation coupled with sulfate reduction on electrodes poised at −0.4 V versus standard hydrogen electrode. Single‐cell activity analysis showed that the electron uptake and metabolic rate via FeS NPs in D. vulgaris were about sevenfold higher than those via native cell‐surface proteins in other SRB.
