API or proprietary test-kits presently used for the detection of bacteria involved in microbial corrosion are designed for specific detection of sulfate-reducing bacteria (SRB). It was recently shown that other sulfidogenic bacteria such as thiosulfate-reducing bacteria (TRB) are also involved in the corrosion of carbon steel. Since these bacteria cannot be detected by SRB test-kits, a new kit was developed for TRB
detection, and validated in field trials.
