“…It is important to note that SRB, such as Desulfovibrio species, were detected only in samples that had been enriched in bacterial growth medium appropriate for SRB. Previous microbiological studies have suggested that SRB play a key role in microbially influenced corrosion (16,23,25,42), yet SRB were not detected in the genetic analysis of These results do not demonstrate that SRB were not present in these pipeline liquids. Rather, these results demonstrate that SRB are present and can be detected after enrichment for their growth but that they were not present among the most abundant bacterial species in these gas pipeline liquids.…”

“…produce organic acids such as acetic, butyric, formatic, lactic, succinic, and propionic acid that may contribute to corrosion (8,22,28,58,60). Desulfovibrio desulfuricans and Desulfovibrio aminophilus are two important SRB that play an important role in metal corrosion (15,16,60) by reducing sulfate and/or sulfur to hydrogen sulfide (H 2 S) (4). Hydrogen sulfide reacts with iron to form black ferrous sulfide (FeS); it also reacts with water to produce an acid condition, accelerating the corrosion process.…”

Culture-independent techniques, denaturing gradient gel electrophoresis (DGGE) analysis, and random cloning of 16S rRNA gene sequences amplified from community DNA were used to determine the diversity of microbial communities in gas industry pipelines. Samples obtained from natural gas pipelines were used directly for DNA extraction, inoculated into sulfate-reducing bacterium medium, or used to inoculate a reactor that simulated a natural gas pipeline environment. The variable V2-V3 (average size, 384 bp) and V3-V6 (average size, 648 bp) regions of bacterial and archaeal 16S rRNA genes, respectively, were amplified from genomic DNA isolated from nine natural gas pipeline samples and analyzed. A total of 106 bacterial 16S rDNA sequences were derived from DGGE bands, and these formed three major clusters: beta and gamma subdivisions of Proteobacteria and gram-positive bacteria. The most frequently encountered bacterial species was Comamonas denitrificans, which was not previously reported to be associated with microbial communities found in gas pipelines or with microbially influenced corrosion. The 31 archaeal 16S rDNA sequences obtained in this study were all related to those of methanogens and phylogenetically fall into three clusters: order I, Methanobacteriales; order III, Methanomicrobiales; and order IV, Methanosarcinales. Further microbial ecology studies are needed to better understand the relationship among bacterial and archaeal groups and the involvement of these groups in the process of microbially influenced corrosion in order to develop improved ways of monitoring and controlling microbially influenced corrosion.Corrosion is a leading cause of pipe failure and is a main component of the operating and maintenance costs of gas industry pipelines (3,10,18,23,30,31,(42)(43)(44)54). Quantifying the cost of corrosion generally, and more specifically the cost associated with microbial corrosion, in the gas industry is not easily done and is controversial. Pipeline corrosion was estimated in 1996 to cost the gas industry about $840 million/year (10), and in 2001 it was estimated that the annual cost of all forms of corrosion to the oil and gas industries was $13.4 billion, of which microbially influenced corrosion accounted for about $2 billion (31). While it is well recognized that chemical and microbial mechanisms both contribute to corrosion, it is uncertain what the relative contribution of microbial activity to overall pipe corrosion is. It has been estimated that 40% of all internal pipeline corrosion in the gas industry can be attributed to microbial corrosion (23, 44), but data are needed to confirm or revise this estimate. Basic research to increase our understanding of the microbial species involved in microbial corrosion and their interactions with metal surfaces and with other microorganisms will be the basis for the development of new approaches for the detection, monitoring, and control of microbial corrosion. A thorough knowledge of the causes of microbially influenced corrosion and an effici...

“…Tal fato pode estar associado aos produtos insolúveis da corrosão do aço aderidos à superfície metálica, como mencionado por Videla [33]. E, também, como afirmam alguns pesquisadores [29][30][31], devido à formação do biofilme aeróbico e à atividade metabólica da bactéria. Para os períodos de imersão pré-estabelecidos, foi medido o valor do pH do meio.…”

A presença de microorganismos em meios aquosos pode alterar significativamente a interface metal/meio, ou reagir diretamente com a superfície do metal. Assim, colaborando para a deterioração química do material metálico. Este trabalho tem como objetivo avaliar a corrosão do aço em meio sulfato na presença da bactéria Salmonella anatum. Para tal feito, foram conduzidos testes de imersão de amostras de aço carbono no meio sulfato, bem como, realizadas análises das amostras por microscopia eletrônica de varredura e espectroscopia de energia dispersiva por raios-X. Também, foram efetuadas medidas de pH do meio. Foi verificada a perda de massa (em termos de concentração total de íons Fe) da amostra para o tempo de imersão. Por outro lado, foi observada a acidificação do meio, variando o pH de 7,3 (no início) para 5,0 (após 21 dias de imersão). As micrografias da superfície do aço evidenciam a extensa formação de biofilme, isto é, observa-se o crescimento de camada de depósito biológico uniforme, porém, não-homogêneo. Sugerese que ocorre a formação de óxidos de ferro e fosfatos inorgânicos sobre a superfície do aço-carbono.Palavras chaves: aço-carbono, corrosão, Salmonella.Carbon steel corrosion into sulphate medium in the presence of bacterium Salmonella anatum ABSTRACTMicroorganisms into aquatic media may alter significantly the metal/media interface, that is, react directly to metal surface. The aim of this work was evaluate the carbon-steel corrosion into sulfate media in the presence of bacterium Salmonella anatum. For this purpose, immersion assay with mass loss (in terms of total Fe ions concentration) was conducted; pH measurements of the electrolyte and superficial analysis by scanning electron microscopy (SEM) and energy dispersive by X-rays analysis (EDX) techniques were conducted. It was verified that the corrosion process rate is practically insignificant for seven day-immersion time. The pH medium has changed from 7.3 to 5.0 (after 21 days). The biologic deposit film has grown on the carbon-steel surface. It is suggested iron oxides and inorganic phosphates onto carbon steel surface are formed on carbon steel surface. Keywords: carbon-steel, corrosion, Salmonella INTRODUÇÃOA corrosão pode ser caracterizada como o ataque químico sobre uma superfície metálica por um meio agressivo a este, desta forma há o retorno do material à forma de óxido em uma reação espontânea para todos os metais, exceto os nobres. Vários são os fatores que afetam o processo de corrosão, entre eles, a temperatura, a umidade, os compostos presentes no meio e os microorganismos, sejam estes, bactérias, fungos e/ou vírus.De acordo com Videla [1], praticamente todos os microorganismos vistos até o momento se relacionam, em menor ou maior grau, aos processos de biocorrosão e bioacumulação (biofouling). Os microorganismos influenciam a corrosão de metais ao favorecer reações eletroquímicas que não são comuns em condições livres de microorganismos e pela alteração da superfície de contato com o meio, seja pela fixação dos próprios microorg...

Microbial activity is the cause of a variety of problems in water injection systems, e.g., microbial corrosion, plugging, and biofouling. Efficient monitoring of Saudi Aramco's vast water injection system requires the development of online and automated technologies for monitoring microbial activities in the system. A previous system review and technology screening has identified five single-analyte strategies [1], which were evaluated in this study with a laboratory-scale setup to determine their applicability for automated determination of microbial activity in the injection water system. Four of the five single-analyte measuring principles tested in the laboratory setup were deemed less suitable for automation and/or reliable for use in the detection of microbial activity in the company injection water system. These four principles were: luminescence assay for adenosine-5'-triphosphate (ATP), detection and electrochemical measurements of H2S, determination of pH by electrochemical sensor, and measurement of oxidation-reduction potential (ORP). The strategy of staining cells with fluorescent DNA dyes, followed by quantification of fluorescence signals, was identified to hold, with proper optimization of DNA staining and fluorescence detection, a very promising potential for integration in automated, online sensors for microbial activity in the injection water system.
