Biologically competitive effect of Desulfovibrio desulfurican and Pseudomonas stutzeri on corrosion of X80 pipeline steel in the Shenyang soil solution.
TL;DR: In this paper , the authors investigated the corrosion mechanism of X80 carbon steel in the presence of nitrate reducing bacteria (NRB), sulfate reducing bacteria or both in the Shenyang soil solution.

Biotic enhancement of Desulfovibrio desulfuricans on multi-factor influenced corrosion of X80 steel in saline soil
TL;DR: In this article , the authors investigated the corrosion behavior of X80 steel in the condition presence of AC, Desulfovibrio desulfuricans and elastic stress in saline soil, showing that microbes played a critical role in enhancing the synergistic effect.

Mechanistic diversity between nitrate and nitrite on biocorrosion of X80 pipeline steel caused by Desulfovibrio desulfurican and Pseudomonas stutzeri
TL;DR: In this article , the effects of Desulfovibrio desulfurican (D. desulfurus) and Pseudomonas stutzeri (P. stutzersi) on the biocorrosion of X80 pipeline steel for different nitrate and nitrite concentrations were studied.

Corrosion mechanism of Pseudomonas stutzeri on X80 steel subjected to Desulfovibrio desulfuricans under elastic stress and yield stress
TL;DR: In this article , the performance of X80 steel for Desulfovibrio desulfuricans and Pseudomonas stutzeri under elastic stress and yield stress was performed in neutral soil environment.
