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.
采用电化学和表面分析技术研究了鼠尾草提取物对铜绿假单胞菌（Pseudomonas aeruginosa）影响的 304L 不锈钢（SS）微生物腐蚀（MIC）的缓解作用。提取物通过 HPLC-Q-TOF-MS 进行了表征，并评估了其抗生物膜性能。数据显示提取物中存在一些已知的抗菌和防腐化合物。鼠尾草提取物能有效阻止生物膜的形成和抑制成熟生物膜。电化学结果表明，铜绿假单胞菌加速了 304L SS 的 MIC，而提取物的存在则以 97.5±1.5%的抑制效率防止了 MIC。这归因于提取物中的一些化合物在 304L SS 表面吸附形成了一层保护膜。
