“…through direct reactions with concrete), while the biogenic sulfuric acid is the main culprit for the significant corrosion reported for concrete (House, 2013;Sun, 2015;Wells et al, 2009). While for MIC of metal, both SRB and SOB can induce significant corrosion (Javaherdashti, 2017;Little & Lee, 2007). Some of the phenomena reported for MIC of carbon steel are summarized below.…”

Concrete and carbon steel are among the most used materials in many industries, such as infrastructure, transportation and manufacturing. Surfaces of both materials, when exposed to non-sterile environments, can be the sites of biological activities of various microorganisms. Many of the activities are deleterious. From the long-term perspective, both concrete and metal can deteriorate and may ultimately lose their original functionalities. The deterioration of materials caused by microorganisms is known as microbiologically influenced (induced) corrosion (MIC)

“…It is noted that besides carbon steel, microorganisms can cause the corrosion of many other metals as well, e.g. aluminum alloy, magnesium, copper, silver, zinc and even stainless steel (Javaherdashti, 2017;Zhou et al, 2018). Nevertheless, carbon steel is used in much larger quantities than other metallic materials (Enning & Garrelfs, 2014).…”

“…The impacts of biofilm formation on metals and other materials manifest as biofouling, contamination, and microbiologically influenced corrosion (MIC) [ 1 , 2 , 3 , 4 ]. MIC alone can be expected to contribute 20–30% of all global corrosion costs, amounting to a conservative USD 30–50 billion per annum [ 5 , 6 ]. Biofouling and MIC are not well understood or effectively controlled in the marine environment, leading to the application of toxic, broad-spectrum chemical treatments (biocides).…”

Multispecies biofilms represent a pervasive threat to marine-based industry, resulting in USD billions in annual losses through biofouling and microbiologically influenced corrosion (MIC). Biocides, the primary line of defence against marine biofilms, now face efficacy and toxicity challenges as chemical tolerance by microorganisms increases. A lack of fundamental understanding of species and EPS composition in marine biofilms remains a bottleneck for the development of effective, target-specific biocides with lower environmental impact. In the present study, marine biofilms are developed on steel with three bacterial isolates to evaluate the composition of the EPSs (extracellular polymeric substances) and population dynamics. Confocal laser scanning microscopy, scanning electron microscopy, and fluorimetry revealed that extracellular DNA (eDNA) was a critical structural component of the biofilms. Parallel population analysis indicated that all three strains were active members of the biofilm community. However, eDNA composition did not correlate with strain abundance or activity. The results of the EPS composition analysis and population analysis reveal that biofilms in marine conditions can be stable, well-defined communities, with enabling populations that shape the EPSs. Under marine conditions, eDNA is a critical EPS component of the biofilm and represents a promising target for the enhancement of biocide specificity against these populations.

“…Microbiologically influenced corrosion (MIC) is the term designated to the acceleration of a corrosion process due to the activities of microorganisms where the electrochemical reactions are enhanced because of bacterial metabolic products [1][2][3][4]. Microorganisms contribute to corrosion processes by either direct influence on the rate of anodic or cathodic reactions or by changing surface film characteristics due to biofilm formation [4].…”

Microscopic, electrochemical and surface characterization techniques were used to investigate the effects of iron reducing bacteria (IRB) biofilm on carbon steel corrosion for 72 and 168 h under batch conditions. The organic nutrient availability for the bacteria was varied to evaluate biofilms formed under nutritionally rich, as compared to nutritionally deficient, conditions. Focused ion beam-scanning electron microscopy (FIB-SEM) was used to investigate the effect of subsurface biofilm structures on the corrosion characteristics of carbon steel. Hydrated biofilms produced by IRB were observed under environmental scanning electron microscope (ESEM) with minimal surface preparation, and the elemental composition of the biofilms was investigated using energy dispersive spectroscopy (EDX). Attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR) was used to provide information on the organic and inorganic chemical makeup of the biofilms. Electrochemical techniques employed for assessing corrosion, by open circuit potential, linear polarization and potentiodynamic polarization tests indicated no significant difference in the corrosion resistance for carbon steel in IRB-inoculated, compared to the abiotic solutions of common Postgate C after 72 and 168 h. However, the steel was found to be more susceptible to corrosion when the yeast extract was removed from the biotic environment for the 168 h test. In the absence of yeast nutrient, it is postulated that IRB received energy by transforming the protective film of Fe3+ into more soluble Fe2+ products.
