The corrosion behaviors of four pure metals (Fe, Ni, Mo and Cr) in the presence of sulfate reducing bacteria (SRB) were investigated in enriched artificial seawater (EASW) after 14-day incubation. Metal Fe and metal Ni experienced weight losses of 1.96 mg cm -2 and 1.26 mg cm -2 , respectively. In contrast, metal Mo and metal Cr exhibited minimal weight losses, with values of only 0.05 mg cm -2 and 0.03 mg cm -2 , respectively. In comparison to Mo (2.2 × 10 6 cells cm -2 ) or Cr (1.4 × 10 6 cells cm -2 ) surface, the sessile cell counts on Fe (4.0 × 10 7 cells cm -2 ) or Ni (3.1 × 10 7 cells cm -2 ) surface was higher.
