Field testing of an enzymatic quorum quencher coating additive to reduce biocorrosion of steel

We have evaluated the potential of a stable quorum quenching lactonase enzyme to reduce biocorrosion in the field. In an attempt to evaluate the effects of signal disruption of surface microbial communities and the reasons for lower corrosion levels, 16S rRNA sequencing was performed and community populations were analyzed. Interestingly, surface communities are similar between all treatments, and only minor changes can be observed.
