Figure 2.

3D profilometry representations of CS surfaces after 49 d exposure under different oxygen conditions and bacterial additions in amended IO. Dashed lines indicate locations of associated extracted line scan profiles. Areas with little to no attack are represented as gray. (a) Uniform morphology of corrosion after aerobic exposure with FeOB M. ferrooxydans PV-1. (b) Light uniform corrosion after anaerobic exposure with FeRB Geothermobacter sp. HR-1. (c) Roughened surface with areas of deep attack surrounded by unattacked metal after exposure to aerobic conditions with co-cultures of FeOB M. ferrooxydans PV-1 and FeRB Geothermobacter sp. HR-1.
