摘要: Abstract The biofilm colonization dynamics of Pseudomonas NCIMB 2021 and Desulfovibrio desulfuricans (ATCC 27774) on 304 stainless steels (304 SS) was evaluated using atomic force microscopy (AFM) in simulated seawater-based media under aerobic anaerobic conditions. Results showed that the formed coupon surface by two strains bacteria increased coverage, heterogeneity thickness with exposure time, thus resulting deterioration steel substratum underneath form pitting corrosion. depth pits induced D. larger than 2021, which mainly attributed to enhanced corrosion SS coupons biogenic sulfide ions, as revealed results X-ray photoelectron spectroscopy (XPS) Tafel polarization curves. AFM also used determine cell attachment/detachment processes quantifying tip–cell interaction forces. interactive forces between tip bacterial were considerably smaller those cell–cell interface due accumulation extra-cellular polymeric substances (EPS) for both strains. Furthermore, adhesion over cells verified be more attractive former being a slime-producer.
