- API contains nutrients such as proteins, organic acids, and sulfate specially formulated to facilitate the growth of oil and gas field SRB
- The redox potential of properly made API, typically less than -300mV, will allow for the reduction of the sulfate to sulfide by SRB
- The biogenic sulfide created by SRB then reacts with dissolved iron species, as well as the iron in the nail. This reaction precipitates a black iron sulfide solid. Black precipitation in the vial is a positive indication for SRB
