Table 4.

The number of pits and the instantaneous corrosion rates for replicates of the hydrocarbon and fatty acid oxidizing cultures as well as the spent medium incubations.

ND, Not detectable.

“–”, Replicate not done or data not available.

^*The metal had pitting on the side but could not be quantified by the profilometer.

1/R_p = 10⁻⁵ ohms⁻¹ cm⁻², <0.0254 mmpy; 10⁻⁴ ohms⁻¹ cm⁻², 0.0254–0.127 mmpy; 10⁻³ ohms⁻¹ cm⁻², 0.127–0.508 mmpy.
