ARAYA, Raquel; BOBADILLA, Carla V; ROSALES, Blanca M y VERA, Rosa. Corrosion of Aeronautical Aluminium Alloys and its Components Related to the Proteic Expression of the Fungus Hormoconis resinae. Inf. tecnol. [online]. 2008, vol.19, n.2, pp.59-68. ISSN 0718-0764. http://dx.doi.org/10.4067/S0718-07642008000200008.
This article shows that the metabolic needs of oligoelements constitute the driving force of the microbiologically influenced corrosion produced by Hormoconis resinae on aeronautical aluminium alloys. Protein profiles of biofilms generated by fungal strains cultivated in aeronautical fuel were compared by electrophoresis in poliacrylamide gels. The morphology attack of alloys, its component metals and the growth of hyphae in cultures were characterized by means of environmental scanning electronic microscopy. One of the main conclusions is that corrosion would be associated to alloying elements that would act as oligoelements for the microorganism.
