Bacterial influenced corrosion of AISI 316 stainless steels (SS) and ASTM A36 carbon steel by two strains of sulfate reducing bacteria (SRB) were analyzed. Thermophilic and mesophilic bacteria were isolated from the condensate fluid of "Los Azufres", a geothermal electric field located in the State of Michoacan at Central Mexico. Anaerobic corrosion tests were carried out for 15, 30 and 60 days in lactate-containing media at 50 C and 40 C. Scanning electron microscopy (SEM) was used to determine corrosion morphology. Pitting density was determined with an optical microscope. Corrosion potential, anodic potentiodynamic polarization curves and pH values were measured under anaerobic conditions. Results show that the microbial activity influenced the overall corrosion process, whereas, pitting corrosion and localized attack corrosion (LAC) were found. The anodic polarization curves show that passivation and activation processes should take place on the steel surface of the sample and pH decreases as the exposure time increases.

“…Nevertheless, 304 SS, as a low grade austenitic SS, is particularly susceptible to biocorrision of sulfate-reducing bacteria (SRB) and to localized corrosion by chloride and reducing sulfur compounds (Antony et al, 2007;Little and Wagner, 1993). The accelerated corrosion of SS by SRB is mainly caused by cathodic depolarization (Hamilton, 1985;Iverson, 1966), production of aggressive sulfide ions (Little et al, 2000), binding metal ions by extracellular polymeric substances (EPS) (Beech and Sunner, 2004), and formation of aggressive ferrous sulfide (Tributsch et al, 1998). Thus, biocorrosion is a great concern in aquatic environments and for maritime industries, as $20-30% of corrosions are associated with biocorrosion at a direct cost of 30-50 billion dollars per year worldwide (Flemming, 1996).…”

To enhance the biocorrosion resistance of stainless steel (SS) and to impart its surface with bactericidal function for inhibiting bacterial adhesion and biofilm formation, well-defined functional polymer brushes were grafted via surface-initiated atom transfer radical polymerization (ATRP) from SS substrates. The trichlorosilane coupling agent, containing the alkyl halide ATRP initiator, was first immobilized on the hydroxylated SS (SS-OH) substrates for surface-initiated ATRP of (2-dimethylamino)ethyl methacrylate (DMAEMA). The tertiary amino groups of covalently immobilized DMAEMA polymer or P(DMAEMA), brushes on the SS substrates were quaternized with benzyl halide to produce the biocidal functionality. Alternatively, covalent coupling of viologen moieties to the tertiary amino groups of P(DMAEMA) brushes on the SS surface resulted in an increase in surface concentration of quaternary ammonium groups, accompanied by substantially enhanced antibacterial and anticorrosion capabilities against Desulfovibrio desulfuricans in anaerobic seawater, as revealed by antibacterial assay and electrochemical studies. With the inherent advantages of high corrosion resistance of SS, and the good antibacterial and anticorrosion capabilities of the viologen-quaternized P(DMAEMA) brushes, the functionalized SS is potentially useful in harsh seawater environments and for desalination plants.

“…Microbial sulfate reduction by these microorganisms is recognized as a widely distributed process of great ecological importance (29,54). Historical interest in sulfate-reducing bacteria has been focused on their involvement in biocorrosion of ferrous metals in the petroleum industry and of concrete structures in wastewater collection systems (15,24). More recent studies (7,25,27,28) have documented the ability of a number of sulfate-reducing bacteria to reduce soluble metal oxyanions to insoluble forms, a process of great potential in the bioremediation of toxic heavy metals and radionuclides such as chromium and uranium (11,56).…”

Many of the proteins that are candidates for bioenergetic pathways involved with sulfate respiration in Desulfovibrio spp. have been studied, but complete pathways and overall cell physiology remain to be resolved for many environmentally relevant conditions. In order to understand the metabolism of these microorganisms under adverse environmental conditions for improved bioremediation efforts, Desulfovibrio vulgaris Hildenborough was used as a model organism to study stress response to nitrite, an important intermediate in the nitrogen cycle. Previous physiological studies demonstrated that growth was inhibited by nitrite and that nitrite reduction was observed to be the primary mechanism of detoxification. Global transcriptional profiling with whole-genome microarrays revealed coordinated cascades of responses to nitrite in pathways of energy metabolism, nitrogen metabolism, oxidative stress response, and iron homeostasis. In agreement with previous observations, nitrite-stressed cells showed a decrease in the expression of genes encoding sulfate reduction functions in addition to respiratory oxidative phosphorylation and ATP synthase activity. Consequently, the stressed cells had decreased expression of the genes encoding ATP-dependent amino acid transporters and proteins involved in translation. Other genes up-regulated in response to nitrite include the genes in the Fur regulon, which is suggested to be involved in iron homeostasis, and genes in the Per regulon, which is predicted to be responsible for oxidative stress response.The sulfate-reducing bacteria represent a group of microorganisms characterized by the ability to use sulfate as an electron acceptor in anaerobic respiration (47). Microbial sulfate reduction by these microorganisms is recognized as a widely distributed process of great ecological importance (29,54). Historical interest in sulfate-reducing bacteria has been focused on their involvement in biocorrosion of ferrous metals in the petroleum industry and of concrete structures in wastewater collection systems (15,24). More recent studies (7, 25, 27, 28) have documented the ability of a number of sulfate-reducing bacteria to reduce soluble metal oxyanions to insoluble forms, a process of great potential in the bioremediation of toxic heavy metals and radionuclides such as chromium and uranium (11, 56).To effectively immobilize heavy metals and radionuclides using sulfate-reducing bacteria, it is important to understand the microbial response to adverse environmental factors common in contaminated subsurface environments. One such factor is the high nitrate concentration of many contaminated sites at the nuclear weapon complexes in the United States managed by the Department of Energy (39,49). The presence of nitrate may pose a specific stress to sulfate-reducing bacteria as nitrate has been observed to suppress sulfate reduction activity in situ (9, 21). However, it has been suggested that nitrite, an intermediate that transiently accumulates during nitrate reduction (3,23,58), is directly...
