“…Pseudomonas species, the most prevalent in industrial water and seawater, have been reported in the corrosion of mild steel, stainless steel, and aluminum alloys in marine and industrial habitats [54,55]. Aerobic Pseudomonas species are recognized to be the pioneer colonizer in biofilm formation; their primary role appears to be to create an oxygen-free environment to harbor other corrosive bacteria (such as the sulphate reducing bacteria).…”

An analysis of a culturable corrosive bacterial community in water samples from a cooling tower was performed using traditional cultivation techniques and its identification based on 16S rRNA gene sequence. Seven aerobic bacterial species were identified: Pseudomonas putida ARTYP1, Pseudomonas aeruginosa ARTYP2, Massilia timonae ARTYP3, Massilia albidiflava ARTYP4, Pseudomonas mosselii ARTYP5, Massilia sp. ARTYP6, and Pseudomonas sp. ARTYP7. Although some of these species have commonly been observed and reported in biocorrosion studies, the genus Massilia is identified for the first time in water from a cooling tower. The biocorrosion behaviour of copper metal by the new species Massilia timonae ARTYP3 was selected for further investigation using a weight loss method, as well as electrochemical and surface analysis techniques (SEM, AFM, and FTIR). In contrast with an uninoculated system, thin bacterial biofilms and pitting corrosion were observed on the copper metal surface in the presence of M. timonae. The use of a biocide, bronopol, inhibited the formation of biofilm and pitting corrosion on the copper metal surface.

“…Pseudomonas species are frequently found in industrial water and seawater and have been reported in the corrosion of mild steel, stainless steel and aluminium alloys in marine and industrial habitats (Moreno et al 1993;Ceyhan and Ozdemir 2008;Liu et al 2009). This bacterium has been associated with early stages of biofilm formation in metallic material surfaces (Doğruöz et al 2009b;Liu et al 2009Liu et al , 2011; their primary role appears to be the establishment of an oxygen-free environment to harbor other potentially corrosive bacteria with diverse oxidative profiles (Pedersen et al 1988).…”

“…Besides total heterotrophic bacteria, Pseudomonas aeruginosa was chosen because it has been extensively studied and associated with biofilms and to compare the system in this study to those of other researchers who reported the efficacy of diverse biocides in the control of microbiota using P. aeruginosa biofilms (Costerton 1999;Moreno et al 1993;Ceyhan andOzdemir 2008, Blasco et al 2008;Liu et al 2009Liu et al , 2011. For monitoring sessile bacteria, glass surfaces were also used along with stainless and carbon steel coupons; also, corrosion coupons and linear polarization resistance (LPR) probes were used for monitoring corrosion in the two cooling towers.…”

The study was planned to quantify the distribution of bacteria between bulk water and biofilm formed on different materials in an industrial scale cooling tower system of an oil refinery operating with clarified and chlorinated freshwater (CCW) or chlorinated tertiary effluent (TRW) as makeup water. The sessile and planktonic heterotrophic bacteria and Pseudomonas aeruginosa densities were significantly higher in the cooling tower supplied with clarified and chlorinated freshwater (CTCW) (p < 0.05). In the two towers, the biofilm density was higher on the surface of glass slides and stainless steel coupons than on the surface of carbon steel coupons. The average corrosion rates of carbon steel coupons (0.4-0.8 millimeters per year (mpy)) and densities of sessile (12-1.47 × 10(3) colony-forming unit (CFU) cm(-1)) and planktonic (0-2.36 × 10(3) CFU mL(-1)) microbiota remained below of the maximum values of reference used by water treatment companies as indicative of efficient microbial control. These data indicate that the strategies of the water treatment station (WTS) (free chlorine) and industrial wastewater treatment station (IWTS) followed by reverse electrodialysis system (RES) (free chlorine plus chloramine) were effective for the microbiological control of the two makeup water sources.

“…[5] On the other hand, some bacterial strains, which include Pseudomonas fragi, Escherichia coli DH5, Pseudomonas flava, and Paenibacillus polymyxa, are known to inhibit corrosion when they reside in biofilms. [6][7][8][9] Conventionally, the addition of biocides to water systems is usually a direct attempt to prevent the development of biofilms within which microbes secrete highly aggressive acidic or alkaline compounds. These biocides are both hazardous to the environment as well as to anyone working in the immediate vicinity.…”

The addition of biocides to water systems has been the most direct attempt to limit or mitigate the formation of surface biofilms that lead to the development of microbial‐induced corrosion (MIC), a process that costs industry millions of pounds annually. The efficacy of this approach is dependent upon a) the biocide being delivered to all water–metal substrate interaction sites and b) the biocide remaining active, therein preventing biofilm development/growth. Anti‐fouling biocide additions to water supplies, or anti‐fungal additives in paints, have an adverse impact upon the environment, for example, tri‐butyl tin is toxic to aquatic life. An alternative non‐toxic approach currently being pursued by the authors involves localizing a biologically active reagent close to the metal substrate. Localization in this case is achieved by synthesizing a hybrid functional sol–gel coating and encapsulating a suitable non‐pathogenic biological component within the sol–gel matrix. Distribution within the sol–gel coating of vegetative bacteria or spores has been confirmed using various microscopy techniques. Electrochemical data in the form of polarization resistance, impedance spectroscopy, and electrochemical noise all show that the presence of either P. fragi or P. polymyxa within a sol–gel coating leads to a corrosion resistance improvement at least 10 times that of an equivalent abiotic coating. Confirmation of this improvement is derived from six months of field trial testing conducted in a tidal estuarine environment. Comparative tests that use a control sol–gel coating immersed within nutrient poor artificial seawater that contained freely suspended P. polymyxa reveal no marked improvement over a control sample in the absence of the endospores.
