A Novel Peptide at a Very Low Concentration Enhanced Biocide Treatment of Corrosive Biofilms

A peptide (labeled as “Peptide A”) was used to enhance tetrakis hydroxymethyl phosphonium sulfate biocide to treat the corrosive sulfate reducing bacterium Desulfovibrio vulgaris and a tough field biofilm consortium on C1018 carbon steel coupons.

Problematic biofilms cause biofouling and biocorrosion (also known as microbiologically influenced corrosion or MIC). Scrubbing (or pigging in the pipeline industry) and biocide dosing are often used to mitigate biofilms. Biofilm consortia deploy various mechanisms to resist biocide treatment. Overtime biocide resistance occurs leading to dosage escalation and eventually rendering a biocide unsuitable for a particular field operation. Biocide enhancers can help overcome or slowdown the trend. In this work a novel peptide was used to enhance THPS (tetrakis hydroxymethyl phosphonium sulfate) biocide mitigation of a pure-strain biofilm and an oilfield biofilm consortium. In both biofilm prevention and biofilm removal tests the peptide at a concentration below 1 ppm (w/w) showed excellent efficacies for the mitigation of the biofilms.

Key words: biocide, peptide, biofilm, microbiologically influenced corrosion
