| Résumé: | The aim of the present work is the evaluation of effect of methanolic extract obtained from Daphne gnidium against biocorrosion
caused by sulphate-reducing bacteria (SRB). Herein, the study of the influence of SRB consortium has been realized
on the biological and electrochemical properties of the carbon steel API5LX60 immersed in water sample obtained from
an Algerian oil field separator. The monitoring of the treatment effects on the SRB performance using kits test and weight
loss methods showed a positive effect of the methanolic extract of D. gnidium as a corrosion inhibitor at a concentration of
0.8 g/L. In the other hand, the weight loss test has generated an efficiency rate of 95.99% at a concentration of 1.6 g/L. A
linear polarization resistance approved these results, and they have given a yield of 91.14% with a polarization resistance
value of 28.9 kΩ cm2 at a concentration of 0.25 g/L. |
