“…From their experiments these writers conclude that iron bacteria play a decided role in the corrosion process, but the authors' investigations indicate that another microbe group with different physiological characteristics is most important. Other papers (8)(9)(10)(11)(12) dealing with the internal attack of iron water pipes state that iron bacteria play a role. The authors agree with Hadley (13) that the role played by iron bacteria in internal iron corrosion has not been clarified by the various investigations.…”

“…Brown (9), who discusses scale formation through iron rust, shows the layers in a cross section of an old tubercle, consisting of ferric hydroxide (formed into a resistant mass by iron bacteria, Gallionella ferruginea) and incrustations of calcium carbonate, a manganese dioxide, and other compounds, whereas the outer surface is covered by a layer of living iron bacteria. The core of the tubercle consists of a dark mass containing ferrous sulfide (FeS).…”

“…It is therefore surprising that our understanding of the role of FeOB in marine MIC is largely anecdotal. As a metabolic group, the FeOB have been recognized since the 1830s (7a), and in the early 1900s, it was suggested that they might be involved in MIC (3). Only a few subsequent studies have attempted to characterize the influence of FeOB on steel corrosion (e.g., see references 48 and 51).…”

Microbiologically influenced corrosion (MIC) of mild steel in seawater is an expensive and enduring problem. Little attention has been paid to the role of neutrophilic, lithotrophic, iron-oxidizing bacteria (FeOB) in MIC. The goal of this study was to determine if marine FeOB related to Mariprofundus are involved in this process. To examine this, field incubations and laboratory microcosm experiments were conducted. Mild steel samples incubated in nearshore environments were colonized by marine FeOB, as evidenced by the presence of helical iron-encrusted stalks diagnostic of the FeOB Mariprofundus ferrooxydans, a member of the candidate class "Zetaproteobacteria." Furthermore, Mariprofundus-like cells were enriched from MIC biofilms. The presence of Zetaproteobacteria was confirmed using a Zetaproteobacteria-specific small-subunit (SSU) rRNA gene primer set to amplify sequences related to M. ferrooxydans from both enrichments and in situ samples of MIC biofilms. Temporal in situ incubation studies showed a qualitative increase in stalk distribution on mild steel, suggesting progressive colonization by stalk-forming FeOB. We also isolated a novel FeOB, designated Mariprofundus sp. strain GSB2, from an iron oxide mat in a salt marsh. Strain GSB2 enhanced uniform corrosion from mild steel in laboratory microcosm experiments conducted over 4 days. Iron concentrations (including precipitates) in the medium were used as a measure of corrosion. The corrosion in biotic samples (7.4 ؎ 0.1 mM) was significantly higher than that in abiotic controls (5.0 ؎ 0.1 mM). These results have important implications for the role of FeOB in corrosion of steel in nearshore and estuarine environments. In addition, this work shows that the global distribution of Zetaproteobacteria is far greater than previously thought.

“…Role of FeOB in drinking water treatment. The existence and relevance of FeOB in drinking water treatment have been recognized from the early days of centralized works for water supply (Brown, 1904). In 1882, just five years after startup of operations, all Berlin (Germany) Water Works were forced to switch from groundwater to surface water because of a so‐called “Eisenkalamität” (iron calamity) in the waterworks and distribution systems (Beger & Beger, 1928).…”

The Role of FeOB in Engineered Water Ecosystems: A Review

Iron‐oxidizing bacteria have a long history with the water industry, stemming primarily from their role as nuisance organisms that can cause clogging, corrosion, and fouling in water distribution systems. Recent studies of these bacteria in natural ecosystems have greatly increased the knowledge of their taxonomy, diversity, and detection, as well as their basic ecology and physiology. Recent work on the applied aspects of iron oxidizers indicates that they are important in biofiltration processes and suggests that there may be unrealized benefits in treating them as beneficial microbes. This review aims to stimulate an exchange between microbiological and applied researchers, and toward that end, some areas for future research are discussed. Water industry professionals may gain additional insight into the vital conditions and available research tools for iron‐oxidizing bacteria; microbiologists may discover new—and more or less controlled—environmental habitats for basic research that also supports applications in water treatment.
