Methanolic extract of Artemisia pallens (MEAP) (Asteraceae) was explored as greenbiocorrosion inhibitor for mild steel 1010 in 1.5% sodium chloride environment. Bacillus megaterium SKR7 induces the development of biofilm on the metal surface and forms the pitting corrosion. MEAP was showed (25 ppm) optimum inhibition effect of biocorrosion and further corrosion rate was highly reduced (0.3335 mm/year) than the control system (0.009 mm/year). The electrochemical study has supported the results with a higher value of total resistance (34 Ω cm2) when compared to control systems. It reveals the formation of a protective layer on the metal surface and reduces the adsorption of biofilm. This was due to the antimicrobial effect of MEAP. Overall, the results recognized that MEAP used as a green corrosion inhibitor for MS 1010 with 83% inhibition efficiency.

巨大芽孢杆菌对低碳钢的生物腐蚀和淡蒿甲醇提取物作为天然腐蚀抑制剂的作用

在 1.5% 氯化钠环境中，研究了淡蒿（MEAP）（菊科）的甲醇提取物作为低碳钢 1010 的绿色生物腐蚀抑制剂。巨大芽孢杆菌 SKR7 诱导金属表面生物膜的形成并形成点蚀。MEAP 显示出 (25 ppm) 最佳的生物腐蚀抑制效果，并且进一步的腐蚀速率 (0.3335 毫米/年) 比对照系统 (0.009 毫米/年) 大大降低。与控制系统相比，电化学研究以更高的总电阻值 (34 Ω cm2) 支持结果。它揭示了金属表面保护层的形成并减少了生物膜的吸附。这是由于MEAP的抗菌作用。全面的，
