Abstract
- The mitigation of microbiologically influenced corrosion (MIC) of 304L stainless steel (SS) against Pseudomonas aeruginosa by a Salvia officinalis extract was investigated using electrochemical and surface analysis techniques. The extract was characterized by HPLC-Q-TOF-MS and its antibiofilm property was evaluated. The data revealed the presence of well-known antimicrobial and anticorrosion compounds in the extract. The S. officinalis extract was found effective in preventing biofilm formation and inhibiting mature biofilm. Electrochemical results indicated that P. aeruginosa accelerated the MIC of 304L SS, while the extract was found to prevent the MIC with an inhibition efficiency of 97.5 ± 1.5%. This was attributed to the formation of a protective film by the adsorption of some compounds from the extract on the 304L SS surface. Unlabelled Image • Pseudomonas aeruginosa biofilm accelerates the corrosion of 304L stainless steel. • Salvia officinalis extract effectively prevents the P. aeruginosa biofilm formation. • S. officinalis extract successfully removes the mature P. aeruginosa biofilm. • S. officinalis compounds adsorb on the 304L SS and form a protective layer. • Experimental data confirm the MIC mitigation by the extract.
