... dosing leads to resistance by microbes over time. In this work, D-amino acids were used to enhance the tetrakis (hydroxymethyl) phosphonium sulfate (THPS) biocide against a tough field biofilm consortium on C1018 carbon steel coupons. An equi-mass D-amino acid mixture ( D-mix ) of four D-amino acids (D...

... Abstract Biocorrosion or microbiologically influenced corrosion (MIC) is a major problem in many industries, especially the oil and gas industry. Biofilms are the culprits of MIC. In this work, D-amino acids were used to enhance two biocides, namely alkyldimethylbenzylammonium chloride (ADBAC...

... treatment cycles. It is anticipated that the application of the same biocide will selectively promote resistant microbes. Overtime, this can lead to the biocide dosage escalating, resulting in a cost increase and environmental concerns. Previously published work demonstrated that some D-amino acids...

... molecules with peptide stems consisting of four alternating L- and D-amino acids. The peptide stems all have a D-alanine terminus. It has been hypothesized that replacing the D-alanine terminus with another D-amino acid sends a biofilm dispersal signal. Several recent journal papers presented experimental...
