Definition

Corrosion phenomena at a metal–fluid interface whose rate, localisation, or mechanism is materially altered by the presence, metabolism, or biofilm structure of microorganisms; identification requires evidence that microbial activity or biofilm-mediated chemical gradients (for example, sulfide production, oxygen depletion, pH change, or extracellular polymeric substances) has produced electrochemi
