“…B megaterium bacteria have been declared before, by other authors, as fuel tank microbial contaminant of the United States Air Force aviation [21]. The presence of this type of bacteria in fuel tanks and drain valves [23] could be caused by changes in refinery practices and chemical composition of fuels or possibly by the increased use of fuel additives [20]. In the laboratory study using B. megaterium and AA 7075-T6, the results showed, after 14 days, an increase of the corrosion current nearly to three orders of magnitude in comparison with sterile control.…”

“…The accumulated water inside fuel tanks (building with AA 2024-T3) induces the growth of microorganisms and may lead to microbiologically induced corrosion (MIC) of these tank structures. In the past, jet fuel contaminants have been reported to include a diverse group of bacteria and fungi, with the most common contaminant being the fungus Hormoconis resinae [20]. However, Rauch et al [21] investigated microbial contamination in the United States Air Force (USAF) aviation fuel tanks.…”

Aluminum and its alloys are central materials for the aircraft industry. Aluminum alloys (AA) 7075 and 2024 are widely used both in the structures and in brittle sections of the airplanes. The presence of the alloying elements in these metals makes them susceptible to localized corrosion at the same time vulnerable to bacterial attachment. A great number of reports on aircraft deterioration are related to microbial growth by contamination inside fuel storage tanks and aircraft wing tanks; this phenomenon is known as microbiologically influenced corrosion (MIC). As expected, corrosion and biocorrosion increase maintenance costs and time of the aircraft in the hangar. Therefore, the growing interest is to shed light on these issues and develop future inhibition methods. In this chapter, we will give an overview of microbiologically influenced corrosion associated with AA 2024 and 7075 by consortia and bacteria. Three mechanisms of biocorrosion in aluminium alloys have been described. In addition, some alternatives methods to battle the effect of biocorrosion will be shown, these methods are based on green compound which blocking of attached of bacteria and promote the detachment of biofilm, being these a tendency of the last innovation way to inhibit this kind of phenomenon.

“…Analysis of 16S rRNA clone libraries showed Methylobacterium strains to be the dominant organisms in samples of one fuel type (Jet A) and highly significant in another (JP-8), accounting for 55 % and 18 %, respectively, of the total genera identified . Besides fouling, fuel tanks are also subject to microbial corrosion as a consequence of biofilm formation, likely to involve methylobacteria McNamara et al 2005;Rauch et al 2006). …”

“…Anodizing produces thicker insulating films and better corrosion resistance. Soluble fuel components, contaminants, and additives determine the extent and type of microbial growth [30]. The susceptibility of aluminum alloys to localized corrosion makes them particularly vulnerable to MIC [28].…”
