Abstract

This study investigates the effect and mechanism of trimethylamine N-oxide (TMAO) on the corrosion of Q235 steel induced by sulfate reducing bacteria (Pseudodesulfovibrio cashew, P. cashew) in marine environments. Research has found that TMAO can significantly promote the corrosion of Q235 steel by regulating the expression of genes of bacterial electron transfer, increasing bacterial adhesion and metabolic activity. This study provides new insights into the mechanism of microbiologically influenced corrosion in natural marine environments.
