“…The microbes appear to be Actinobacteria based on morphological and ecological similarities to genetic and biochemical identifications of organisms in other copper-rich settings [19,20]. Although there have been many studies that have identified the bacteria on the surface of corroded water supply lines [11,12,13,21,22] this is the first known SEM investigation that not only has found the microbes deep inside the copper corrosion pits but also wedged inside crystallographic planes in the corroded copper. The microbes could be either passively involved in pitting (excreting an acid that dissolved the copper [23,24]) or actively using copper oxidation as a byproduct of energy acquisition [25] or even as a primary energy source [26] although that is typically associated with copper sulfides rather than elemental copper.…”

“…Wagner (1997) did a very thorough literature review with 118 references that attributed pitting of copper water lines to bacteria. Wagner concluded that the most promising preventive measure was by controlling the water chemistry; modulating the alkalinity while optimizing the chloride/sulfate ratio [11]. Reyes (2008) analyzed the microbes that were contributing to the high copper content (blue water) [12].…”

Many copper water lines for municipal drinking water in Santa Fe, New Mexico USA, have developed pinhole leaks. The pitting matches the description of Type I pitting of copper, which has historically been attributed to water chemistry and to contaminants on the copper tubing surface. However, more recent studies attribute copper pitting to microbial induced corrosion (MIC). In order to test for microbes, the copper tubing was fixed in hexamethyldisilazane (HMDS), then the tops of the corrosion mounds were broken open, and the interior of the corrosion pits were examined with scanning electron microscopy (SEM). The analysis found that microbes resembling actinobacteria were deep inside the pits and wedged between the crystallographic planes of the corroded copper grains. The presence of actinobacteria confirms the possibility that the cause of this pitting corrosion was MIC. This observation provides better understanding and new methods for preventing the pitting of copper tubing in municipal water.

“…In seawater, these materials quickly develop a well-adherent biofilm over the surface which generally presents a heterogeneous composition ( Geesey et al, 1986 ; Zuo, 2007 ; Zhang et al, 2019a ). Under the biofilms the presence of reduced pH, organic acids, sulfide, and acidic polysaccharides can compromise the protective passive layer causing severe corrosion ( Wagner and Chamberlain, 1997 ). Geochemical factors of the marine environment such as pH ( Ponsonnet et al, 2008 ), nutrients ( Sheng et al, 2008 ), salinity ( Briand et al, 2017 ), and temperature ( Witt et al, 2012 ) are essential in defining microbial surface colonization.…”

Regardless of the long record of research works based on microbiologically influenced corrosion (MIC), its principle and mechanism, which lead to accelerated corrosion, is yet to be fully understood. MIC is observed on different metallic substrates and can be caused by a wide variety of microorganisms with sulfate-reducing bacteria (SRB) being considered the most prominent and economically destructive one. Copper and its alloys, despite being used as an antimicrobial agent, are recorded to be susceptible to microbial corrosion. This review offers a research overview on MIC of copper and its alloys in anaerobic aqueous environments. Proposed MIC mechanisms, recent work and developments as well as MIC inhibition techniques are presented focusing on potable water systems and marine environment. In the future research perspectives section, the importance and possible contribution of knowledge about intrinsic properties of substrate material are discussed with the intent to bridge the knowledge gap between microbiology and materials science related to MIC.

“…Cells of these microorganisms are embedded within a self-produced matrix of extracellular polymeric substances and exhibit an altered phenotype associated with growth rate and gene transcription (Donlan and Costerton 2002). Biofilms in drinking water systems may affect water quality or induce corrosion of pipes (Lee, O'Connor, and Banerji 1980;Little, Wagner, and Lewandowski 1997;Wagner and Chamberlain 1997;González, Santana, and Mirza-rosca 1998;Gu et al 1998;Starosvetsky et al 2001). Water taste, color, and odor may be degraded (Servais, Laurent, and Randon 1995;Camper et al 1999;Rubulis and Juhna 2007) and the turbidity may increase (Servais, Laurent, and Randon 1995).…”

Diffuse Reflectance Infrared Fourier Transform Spectra of Biofilm-Containing Sediments: Influence of Sample Lyophilization and Drying Temperature

2015

Monitoring of biofilms in sediments formed inside drinking water distribution systems is important due to their destructive activity and their degradation of water quality. The goal of this study was to examine the influence of drying mode and temperature upon sediments containing biofilms using diffuse reflectance infrared Fourier transform spectroscopy. Sediments were collected from sections of potable water pipes and dried at 22, 40, 105 degrees Celsius, or lyophilized. The presence of biofilm residues was demonstrated. Lyophilization of biofilms and drying at temperatures higher than 22 degrees Celsius affected the infrared spectra. The least invasive method involved airdrying of the biofilms at 22 degrees Celsius.
