“…The biological denitrification of groundwater by a combination of a hydrogenotrophic NRB and Fe 0 granules has been studied, and the addition of an NRB, such as Paracoccus denitrificans ATCC 17741, or an NRB-containing microbial consortium generally resulted in faster nitrate removal and faster Fe 0 oxidation than in aseptic controls (25)(26)(27)(28)(29)(30). The bioelectrochemical mechanisms of the NRB-assisted Fe 0 corrosion in these studies are largely unknown.…”

dMicrobiologically influenced corrosion (MIC) of metallic materials imposes a heavy economic burden. The mechanism of MIC of metallic iron (Fe 0 ) under anaerobic conditions is usually explained as the consumption of cathodic hydrogen by hydrogenotrophic microorganisms that accelerates anodic Fe 0 oxidation. In this study, we describe Fe 0 corrosion induced by a nonhydrogenotrophic nitrate-reducing bacterium called MIC1-1, which was isolated from a crude-oil sample collected at an oil well in Akita, Japan. This strain requires specific electron donor-acceptor combinations and an organic carbon source to grow. For example, the strain grew anaerobically on nitrate as a sole electron acceptor with pyruvate as a carbon source and Fe 0 as the sole electron donor. In addition, ferrous ion and L-cysteine served as electron donors, whereas molecular hydrogen did not. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain MIC1-1 was a member of the genus Prolixibacter in the order Bacteroidales. Thus, Prolixibacter sp. strain MIC1-1 is the first Fe Metallic iron (Fe 0 ) and stainless steel corrosion causes a severe economic burden. The annual cost of corrosion worldwide has been estimated to exceed 3% of the world's GDP (http://www .nace.org/uploadedFiles/Publications/ccsupp.pdf). Under aerobic conditions, molecular-oxygen-mediated corrosion may be predominant, whereas under anaerobic conditions, microbiologically influenced corrosion (MIC) is believed to be a major cause of corrosion-related failures (1). Specifically, sulfate-reducing bacteria (SRB) are considered to be major causative microorganisms of MIC in anaerobic environments because FeS has frequently been observed as a major corrosion product (2).The mechanism underlying Fe 0 corrosion by SRB has been explained on the basis of the cathodic-depolarization theory: Fe 0 oxidation occurs at the anode (Fe 0 ¡ Fe 2ϩ ϩ 2e Ϫ ), while protons are reduced to molecular hydrogen at the cathode (2e Ϫ ϩ 2H ϩ ¡ H 2 ). In the presence of SRB, a hydrogenase of the organism consumes either molecular hydrogen or electrons at the cathode, thereby accelerating the anodic Fe 0 oxidation (3, 4). Recently, a methanogenic archaeon and an iron-oxidizing bacterium were shown to cause Fe 0 corrosion (5-7). These reports suggest that diverse microorganisms contribute to metal corrosion.MIC of metallic materials imposes a heavy economic burden, and technologies for MIC control are being actively investigated. However, the process of MIC is still poorly understood, and further research is required. The characterization of Fe 0 -corroding microorganisms and a clear understanding of the mechanism of MIC are required for effective MIC prevention and control. In this study, we isolated a novel Fe 0 -corroding bacterium from a crude-oil sample collected at an oil well and investigated its Fe 0 corrosion activity under a variety of culture conditions.

“…The previously observed acceleration of cathodic reactions in SRB cultures (65,(69)(70)(71) could now be explained by reaction between sulfide and iron rather than by microbial consumption of cathodic H 2 . Since then, occasional attempts to resurrect the theory have been made (38,42,(72)(73)(74), but to date, no culture-based experiment has been able to demonstrate that bacterial consumption of cathodic hydrogen accelerates iron corrosion to any significant extent (39,47,67,75). It should be stressed at this point that the study of a direct corrosive effect of SRB requires the use of essentially organic matter-free cultivation media to avoid unnecessary complication or even misinterpretation of data resulting from the corrosive effects of H 2 S.…”

“…Most studies have focused on the corrosive effects of sulfatereducing bacteria (SRB), but other physiological groups such as thiosulfate-reducing bacteria (40), nitrate-reducing bacteria (41)(42)(43)(44), acetogenic bacteria (45), and methanogenic archaea (38,39,(46)(47)(48)(49) have also been implicated in iron corrosion. Still, the physiological group of environmental microorganisms with a suggested key role in the anaerobic corrosion of iron consists of the SRB (5,6,50,51), which are widespread in many natural as well as engineered aquatic environments.…”

About a century ago, researchers first recognized a connection between the activity of environmental microorganisms and cases of anaerobic iron corrosion. Since then, such microbially influenced corrosion (MIC) has gained prominence and its technical and economic implications are now widely recognized. Under anoxic conditions (e.g., in oil and gas pipelines), sulfate-reducing bacteria (SRB) are commonly considered the main culprits of MIC. This perception largely stems from three recurrent observations. First, anoxic sulfate-rich environments (e.g., anoxic seawater) are particularly corrosive. Second, SRB and their characteristic corrosion product iron sulfide are ubiquitously associated with anaerobic corrosion damage, and third, no other physiological group produces comparably severe corrosion damage in laboratory-grown pure cultures. However, there remain many open questions as to the underlying mechanisms and their relative contributions to corrosion. On the one hand, SRB damage iron constructions indirectly through a corrosive chemical agent, hydrogen sulfide, formed by the organisms as a dissimilatory product from sulfate reduction with organic compounds or hydrogen ("chemical microbially influenced corrosion"; CMIC). On the other hand, certain SRB can also attack iron via withdrawal of electrons ("electrical microbially influenced corrosion"; EMIC), viz., directly by metabolic coupling. Corrosion of iron by SRB is typically associated with the formation of iron sulfides (FeS) which, paradoxically, may reduce corrosion in some cases while they increase it in others. This brief review traces the historical twists in the perception of SRB-induced corrosion, considering the presently most plausible explanations as well as possible early misconceptions in the understanding of severe corrosion in anoxic, sulfate-rich environments. E ver since its first production roughly 4,000 years ago, iron has played a central role in human society due to its excellent mechanical properties and the abundance of its ores. Today, iron is used in much larger quantities than any other metallic material (1) and is indispensable in infrastructure, transportation, and manufacturing. A major drawback is the susceptibility of iron to corrosion. Corrosion of iron and other metals causes enormous economic damage. Across all industrial sectors, the inferred costs of metal corrosion have been estimated to range between 2% and 3% of gross domestic product (GDP) in developed countries (2, 3). These costs are to a large extent caused by corrosion of iron, due to its abundant use and particular susceptibility to oxidative damage. Estimates of the costs attributable to biocorrosion of iron lack a computed basis so that they vary widely, and definite numbers cannot be given with certainty. Still, microbially influenced corrosion (MIC) probably accounts for a significant fraction of the total costs (4-7), and, due to its effects on important infrastructure in the energy industry (such as oil and gas pipelines), costs in the range of billions of...

“…Nitrous oxide was produced from the late exponential phase through the onset of the stationary phase and accounted for about 25% of the nitrate N. No ammonium accumulation was detected. In a separate study workers also detected nitrous oxide production by S. oneidensis MR-1 (16). Therefore, our goal in the present study was to establish the pathway(s) by which S. oneidensis MR-1 uses nitrate for anaerobic respiration.…”

Respiratory Nitrate Ammonification by Shewanella oneidensis MR-1

Anaerobic cultures of Shewanella oneidensis MR-1 grown with nitrate as the sole electron acceptor exhibited sequential reduction of nitrate to nitrite and then to ammonium. Little dinitrogen and nitrous oxide were detected, and no growth occurred on nitrous oxide. A mutant with the napA gene encoding periplasmic nitrate reductase deleted could not respire or assimilate nitrate and did not express nitrate reductase activity, confirming that the NapA enzyme is the sole nitrate reductase. Hence, S. oneidensis MR-1 conducts respiratory nitrate ammonification, also termed dissimilatory nitrate reduction to ammonium, but not respiratory denitrification.
