“…The Pseudomonadaceae mineral waters (Torda), Rhodobacteraceae mineral waters (Slankamen Banja and Lomnički Kiseljak), Rhodobacteraceae-Burkholderiaceae mineral waters (Velika Vrbnica) and Moraxellaceae mineral waters (Obrenovačka Banja) were designated as Proteobacteria mineral waters. An earlier study documented the dominant presence of representatives of the Proteobacteria phylum in biofilm communities [26] that were associated with the development of biocorrosive processes [27]. Also, it is known that Proteobacteria representatives are the most common groups of bacteria in drinking water, and their physiological diversity and ubiquity could have potential implications regarding the sanitary and hygienic safety of the water resources [28].…”

Bacterial metabarcoding analysis by 16S rDNA of five occurrences of mineral waters in Serbia (Torda, Slankamen Banja, Lomnicki Kiseljak, Velika Vrbnica and Obrenovacka Banja) indicated the presence of a high percentage of the Proteobacteria phylum, followed by the Bacteroidetes phylum. The families Rhodobacteraceae, Burkholderiaceae, Pseudomonadaceae, Methylophilaceae and Moraxellaceae were the most dominant in the bacterial flora of the selected occurrences, whereas the most represented genera were Acinetobacter, Pseudorhodobacter, Pseudomonas, Limnohabitans, Massilia, Limnobacter and Methylotenera. The presence of coliform bacteria was not detected. Alpha diversity analysis revealed that Slankamen Banja and Lomnicki Kiseljak were the richest of the selected occurrences, while the mineral waters of Torda, Velika Vrbnica and Obrenovacka Banja were characterized by similar diversity of bacterial communities determined by beta diversity analysis. Physical-chemical analysis revealed the value of total dissolved solids above 1 g/L, as well as elevated concentrations of some metals and non-metals. The research concluded that specific bacteria contribute to the development of biocorrosion and biofouling processes of water intake facilities. In addition, some of these bacteria might be potential indicators of the organic sources of pollution and/or biotechnological natural remediators in the treatment of contaminated waters.

“…Anodic reactions are triggered by corrosive substances such as acids. Microbes increase cathodic processes by utilizing hydrogen, and they may also stimulate corrosion by secreting enzymes and acidic metabolites (Procópio, 2020). The main types of bacteria associated with the corrosion of iron and steel are sulfate-reducing bacteria (SRB), sulfur-oxidizing bacteria, iron oxidizers, iron reducers, manganese oxidizers and microbes that secrete organic acids and produce extracellular polymeric substances (EPS) (Hamilton, 2003).…”

Introduction: Sulphate-reducing bacteria are the major cause of corrosion of underground structure corrosion of underground structures made of mild steel. Objective: This study set out to evaluate the growth pattern of sulphate-reducing bacteria associated with buried mild steel rods in Akure metropolis, Nigeria Methodology: Mild steel rods (12 mm diameter, area 39.97 cm2), were collected from Ondo State Water Corporation (ODSWC), Akure, Nigeria and were buried and monitored for a period of three months. Percentage composition of the mild steel rods was determined. Isolation of sulphate-reducing bacteria was carried out using compounded Postgate C medium. Turbidimetric growth pattern and biochemical characteristics of the isolates were determined using standard protocols. Results: Citrobacter freundii, Citrobacter gilleni, Enterobacter aerogenes, Pseudomonas aeruginosa, Desulfovibrio vulgaris and Bacillus megaterium were the bacterial consortia isolated from the buried mild steel rods. Turbidity was observed to be at low level on the 5th day of sulphate-reducing bacteria (SRB) growth, but increased to optimum on the 10th day of incubation and reduced drastically on the 15th day. The growth outline of sulphate-reducing bacteria (SRB) was confirmed by the swelling turbid periodic growth for all four mediums. Iron (Fe) had the highest percentage mineral composition of 98.7 % whereas lanthanum had the least composition at 0.00031 %. Conclusion: Findings of this study revealed the presence of sulphate-reducing bacteria (SRB) on buried mild steel rods of a water distribution system suggesting induction of corrosion of the underground mild steel pipes.

“…Microbiologically influenced corrosion (MIC) or microbial corrosion refers to corrosion affected by the presence of microorganisms, which leads to the deterioration of materials such as iron, steel, concrete and stone [1][2][3][4]. MIC is a major challenge to many industries including oil, gas and mining [5].…”

Corrosion under flow conditions is a major problem in the transportation industry. Various studies have shown the direct impact of different flow rates on bacteria biofilm formation, mass transfer and resulting different corrosion behaviour of materials in neutral environments. However, little is understood on corrosion under acidic flow conditions. This study investigated the impact of an acidic artificial seawater environment containing Desulfovibrio vulgaris on DSS 2205 microbial corrosion under different velocities (0.25 m.s-1 and 0.61 m.s-1). Experiments containing no bacteria were performed as controls. Bacterial attachment was observed by optical and scanning electron microscope (SEM). Materials corrosion was assessed using open circuit potential (OCP), electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization. Pits formed after potentiodynamic test were observed under SEM. The largest area of bacterial attachment was found on coupons immersed at a velocity of 0.25 m.s-1; however, the corrosion rate was lower than at higher velocity. Shallow pits occurred in the metal coupons when bacteria were present, while deep pits occurred in the controls. The study indicates the positive impact of biofilm formation in corrosion prevention of materials under acidic condition. The nature of corrosion behaviour of duplex stainless is discussed.
