Abstract
Bacteria associated with the biological
sulphur cycle play a particularly dominant
role in the process of metallic corrosion.
This is largely due to the ubiquitous
presence of these bacteria in natural environments1,2.
Unsurprisingly, sulphatereducing
bacteria have been the main
highlight in numerous bio-corrosion investigations.
A vast number of mechanisms3–8
have been proposed in the literature to
explain the rather multifarious process of
anaerobic corrosion. The deterioration of
iron and concrete by aerobic sulphur
bacteria (thiobacilli) is more straightforward.
These bacteria oxidize sulphur
and/or sulphide to sulphuric acid9.
