Author(s): E. Ruiz, J. Duque and W. Aperador

In this article, the behavior of microbiologically induced corrosion is studied byDesulfovibrioaminophilus in AISI 316L stainless steel. Bacterial characterization was conducted by macroscopic and microscopicmorphological and biochemical tests. The growth kinetics is observed
through periodicre views; and electrochemical characterization by impedance diagrams and polarizationcurves Tafel. There cambiar results showed the growth of colonies in the surface material of variable andunstable take aggressive action of generating localized pitting, after the exposure time expolisacaridosmatrix is generated, which reduces the corrosion rate in the sample of AISI 316 L.
