“…Although a biofilm is observed at the MC area in many cases, some investigators have reported that biofilm formation inhibits metal corrosion (Jayaraman et al 1999a and1999b;Ornek et al, 2002). One possibility has been proposed that oxygen depletion by low corrosion activity bacteria inhibits high corrosion activity bacterial growth on the metal surface.…”

“…The cathodic protection method has been applied to some pipelines, but causes them to become fragile because of the hydrogen found in ferritic stainless steel (Ibars et al, 1992). Recently, T. K. Wood and his colleagues have reported that bacilli biofilms inhibited metal corrosion caused by SRB (Jayaraman et al, 1999a and1999b;Ornek et al, 2002). This method seems to be useful if the bacilli biofilms are controlled.…”

We investigated characteristics of the corrosion of stainless steel specimens by bacteria and the effects of using antimicrobial coating on the surface for inhibiting corrosion. Bacillus sp. 2-A and Staphylococcus sp. 2-I cells adhered tightly to a stainless steel SUS304 specimen, formed a microcolony or biofilm, and had highly corrosive activities. Microbially influenced corrosion (MC) was observed under or around adhering cells. However, dead cells were markedly less active than viable cells not only in corroding the specimen but also in adhering to its surface. The culture supernatant was not able to induce the corrosion of SUS304 effectively. A protamine coating on the specimen killed bacterial cells only on its surface , interfered with cell adhesion, and inhibited MC. From these results, adhesion of viable cells to the surface of a SUS304 specimen led to the outbreak of MC. Protamine was also found to be an effective substance tested for protecting the specimen from both cell adhesion and surface MC. We suggest that a protamine coating can be applied as a convenient and inexpensive corrosion prevention method.

“…Do istog zaključka došli su i Jayaraman sa saradnicima [26,35,36] u svojim istrazivanjima ispitujući koroziono ponašanje čelika (SAE 1018), bakra i aluminijuma [37] u prisustvu različitih bakterija (Bacillus brevis 18 i Pseudomonas fragi K). Uočeno je da bakterije Pseudomonas fragi i Escherichia coli DH5α formiraju zaštitni biofilm na površini čelika štiteći ga na taj način od korozije.…”

IZVOD -Proces korozije predstavlja destrukciju kako metalnih tako i nemetalnih materijala usled hemijske ili elektrohemijske interakcije sa okolnom sredinom. Kao rezultat interakcija između površine metala i bakterijskih ćelija, odnosno njihovih metabolita nastaje mikrobiološki indukovana korozija. Međutim, neke vrste mikroorganizama utiču na smanjenje procesa korozije. Shodno tome, analizirana je literatura koja se bavi primenom mikroorganizama kao potencijalnih inhibitora korozije metala. Različite bakterijske vrste ispitivane su kao potencijalni inhibitori korozije. Istaknut je značaj samih mikroorganizama kao i uloga ekstracelularnih polimernih supstanci na koroziono ponašanje metala. Prikazano je da na stepen zaštite pored tipa primenjenog mikroorganizma, utiče i vrsta metala. Takođe, na osnovu prikazanih podataka može se videti da pojedine vrste mikroorganizma mogu uspešno zameniti organske inhibitore koji mogu biti toksični.Ključne reči: mikroorganizmi, korozija, metali, inhibitori, bakterijske vrste ABSTRACT -Corrosion presents the destruction of materials through chemical or electrochemical interactions with their environment. Interactions between the metal surface and bacterial cells or products of their metabolic activities can lead to microbially-influenced corrosion. Also, it is known that certain microorganisms can contribute to corrosion inhibition. In accordance to that, the literature dealing with the application of different microorganisms as a potentialy corrosion inhibitors of metals is investigated.

“…Furthermore, the corrosion products produced due to SRB activity further limits the effectiveness of the antimicrobials used (Videla and Herrera, 2007). Once biocorrosive bacteria become established and form biofilms, it becomes extremely difficult to remove or kill them (Jayaraman et al, 1999b;Zuo et al, 2004). Instead of killing all SRB and other biocorrosive bacteria in the system, a strategy can be developed to prevent the colonisation of SRB from within the biofilm itself (Jayaraman et al, 1999b).…”

“…An increase in depth of biofilm is known to correspond to a greater reduction in corrosion (Jayaraman et al, 1999b). Aerobic P. cichorii was able to inhibit corrosion of mild steel due to a layer of passive oxide products formed during corrosion which was trapped in the biofilm (Chongdar et al, 2005).…”

Metal corrosion is an electrochemical reaction between the environment and a metal, in which microbes are thought to play a very important role. The rates at which various types of metals corrode are dependent upon environmental conditions as well as on the type of metals. The most well studied bacteria involved in biocorrosion are the anaerobic sulphate reducing bacteria (SRB) and other bacteria such as methanogens, acid producers as well as the aerobic iron respirers and manganese oxidisers. The biofilm produced by the microorganisms facilitates bicorrosion by altering the chemistry such as pH, pressure, oxygen levels and nutrients at the interface between the metal and the bulk solution. Therefore biofilms can be used to alter the conditions at a metal surface, and to accelerate or inhibit corrosion. In this review, the proposed mechanisms of how bacteria contribute to the biocorrosion processes and the groups of bacteria involved will be included. Different strategies for biocorrosion control will also be discussed. Biological control strategies such as biocompetitve exclusion and the use of antimicrobial producing biofilm forming bacteria show increasing promise as more effective, environmental friendly and long term method of corrosion controls.
