Evaluation of Biocidal Properties of Vegetable Oil-Based Corrosion Inhibitors Using Bioluminescent Enzymatic Method

摘要

The biocidal activity of carbonic-acid corrosion inhibitors (CIs) based on fatty acids from different vegetable oils against bacterial cells that catalyze biocorrosion processes was investigated using the bioluminescent method for determining the intracellular ATP concentration. It was shown that all obtained CIs exhibited biocidal activity with the amide complexes of fatty acids being the most effective. Their activity was 4.6-fold higher than the activity of nonamide complexes. The minimal inhibitory concentration that causes the death of all bacterial groups was established for the majority of the CIs to be in the range 100—170 mg/mL, and the best biocidal properties against the oil-oxidizing bacteria of the Pseudomonas genus were observed for the CI prepared from the corn oil (27 mg/mL).
