ResumoLittle is known about the microbiologically influenced corrosion of metals exposed to the marine tidal zone alternately immersed by seawater. Corrosion of EH40 steel affected by Halomonas titanicae was investigated under alternate and full immersion in the present work. It was found that the corrosion was accelerated by the transition from full immersion to alternate pattern in abiotic media, but the corrosion inhibition efficiency of H. titanicae towards steel was enhanced by this transition. These differences were associated with thin electrolyte layers, the increase in the number of sessile cells, and their probably enhanced aerobic respiration activity by alternate immersion.
