英文摘要Toxic and non-toxic alloy coupons were exposed to various environmental conditions annually to study microbiologically influenced corrosion (MIC) communities. This study provides the first evidence of grampositive bacteria responsible for MIC-accelerated pitting corrosion on both toxic and non-toxic alloy coupons. Across coupons under different environmental conditions, gram-positive bacteria predominantly showed MICs higher than those of gram-negative bacteria. The main MIC strains B. horikoshii (PQ549955), B. jeotgali (PQ554780), B. safensis (PQ554710), B. infantis (PQ554706), B. aryabhattai (PQ554711), E. mexicanum (PQ554714), S. sciuri (PQ554798), S. haemolyticus (PQ554797), and P. celer (PQ554704) were identified through 16S rDNA sequencing. Marine environments induce more aggressive pitting corrosion than freshwater environments because chloride and sulfur ions in seawater penetrate oxide films on metal surfaces. SEM and 3D laser microscopy results confirmed that marine conditions lead to significantly more aggressive pitting corrosion on the coupons. This study also systematically explored 'One-Pot' green-fused nanomaterials synthesized with Turbinaria ornata (TO) extracts and characterized by various techniques. The TOZnO@CdO-NCs showed maximum activity against P. celer and the least growth inhibition in B. jeotgali and B. safensis. This likely involves the accumulation of TOZnO@CdO-NCs in bacterial cell membranes, disrupting physiological functions or causing cell death. Overall, the TOZnO@CdO-NCs show strong potential as innovative anti-corrosion coatings for marine applications and may soon be incorporated into protective paints.
