Fig. 4: Visualization of microbially induced corrosion (MIC) by bacteria.
From: Understanding biofouling and contaminant accretion on submerged marine structures
Extracellular electron transfer MIC occurs when outer membrane cytochromes scavenge electrons from a surface via (a) direct contact, (b) conductive pili or (c) delivery through soluble electron shuttles. d Metabolite MIC occurs when corrosive bacterial metabolic products or their derivatives degrade a surface.
