“…Before biofilm observation, the coupons were first cleaned with pH 7.40 phosphate-buffered saline (PBS) solution for 15 s, and then soaked in 2.5% (w/w) glutaraldehyde solution for 8 h at 10 °C to fix the biofilm. Afterward, the coupons were dehydrated with 50% (v/v), 70%, 80%, 90%, and 95% ethanol sequentially for 10 min at each concentration and 100% ethanol for 30 min at the end (Cui et al, 2020). Then, the coupon surfaces were sputter coated with Au to provide surface conductivity.…”

It is known that starved sulfate-reducing bacterial biofilms corrode carbon steel more aggressively because they use electrons from elemental iron oxidation as an alternative source of energy. This work used carbon source starvation to vary MIC (microbiologically influenced corrosion) severity for studying subsequent MIC impacts on the degradation of X80 carbon steel mechanical properties. X80 square coupons and dogbone coupons were immersed in ATCC 1249 culture medium (200 ml in 450-ml anaerobic bottles) inoculated with Desulfovibrio vulgaris for 3-day pre-growth and then for an additional 14 days in fresh media with adjusted carbon source levels for starvation testing. After the starvation test, the sessile cell counts (cells/cm2) on the dogbone coupons in the bottles with carbon source levels of 0, 10, 50, and 100% (vs that in the full-strength medium) were 8.1 × 106, 3.2 × 107, 8.3 × 107, and 1.3 × 108, respectively. The pit depths from the X80 dogbone coupons were 1.9 μm (0%), 4.9 μm (10%), 9.1 μm (50%), and 6.4 μm (100%). The corresponding weight losses (mg/cm2) from the square coupons were 1.9 (0%), 3.3 (10%), 4.4 (50%), and 3.7 (100%). The 50% carbon source level had the combination of carbon starvation without suffering too much sessile cell loss. Thus, both its pit depth and weight loss were the highest. The electrochemical tests corroborated the pit depth and weight loss trends. The tensile tests of the dogbone coupons after the starvation incubation indicated that sulfate-reducing bacteria (SRB) made X80 more brittle and weaker. Compared with the fresh (no-SRB-exposure) X80 dogbone coupon’s ultimate tensile strain of 13.6% and ultimate tensile stress of 860 MPa, the 50% carbon source level led to the lowest ultimate tensile strain of 10.3% (24% loss when compared with the fresh dogbone) and ultimate tensile stress of 672 MPa (22% loss). The 100% carbon source level had a smaller loss in ultimate tensile strain than the 50% carbon source level, followed by 10% and then 0%. Moreover, the 100% carbon source level had a smaller loss in ultimate tensile strength than the 50%, followed by 10% and 0% in a tie. This outcome shows that even in the 17-day short-term test, significant degradation of the mechanical properties occurred and more severe MIC pitting caused more severe degradation.

Three types of stainless steel (304 SS, 410 SS, and 2205 SS) were evaluated for their corrosion behaviors in microbiologically influenced corrosion (MIC) by Desulfovibrio ferrophilus strain IS5, a relatively new and very corrosive sulfate-reducing bacteria (SRB) strain. The incubation lasted for 7 days in enriched artificial seawater at 28°C and the results showed that 410 SS had a rather large weight loss (6.2 mg/cm2) and a maximum pit depth (118 µm), but 2205 SS and 304 SS did not suffer from significant weight loss or pitting. Electrochemical tests indicated that 2205 SS was slightly more resistant to SRB MIC than 304 SS, while 410 SS was far less resistant.

Microbiologically influenced corrosion (MIC) accounts for a large proportion of industrial steel corrosion, among which the most representative microorganism is sulfatereducing bacteria (SRB). The direct application of the fungicides may cause high utilization dosage, increased bacterial resistance, and environmental pollution and cannot realize the effective longlasting antimicrobial and corrosion inhibition performance. Herein, a novel kind of nanocapsule with both bactericidal and corrosion inhibition functions is developed. The hollow mesoporous silica (HMSNs) is used as the carrier and encapsulated with benzotriazole (BTA) inhibitors; their surface microchannels are sealed with the bactericide metronidazole (MNZ)-loaded ZIF-8 nanovalve. The high-performance liquid chromatography results confirm that the encapsulation amounts of MNZ and BTA in the nanocapsules are 7.67% and 4.20%, respectively. Moreover, the as-prepared BTA-HMSN/ZIF-8-MNZ nanocapsules exhibit a typical sulfide ion-responsive characteristic. The release rate of the encapsulated MNZ and BTA rises with the increased sulfide-ion concentrations, and the cumulative release amount reaches 80% after 24 h when the sulfide-ion concentration attains 2 mM. Furthermore, the antimicrobial performance of BTA-HMSN/ZIF-8-MNZ nanocapsules is evaluated in SRB solutions. The survival SRB amounts decrease evidently with the increased nanocapsule concentration, and the antibacterial efficiency is nearly 100% at a concentration of 250 μg•mL −1 . The weight loss test and surface analysis also confirm the excellent corrosion inhibition ability of the BTA-HMSN/ZIF-8-MNZ nanocapsules to Q235 steels, whose inhibition efficiency is up to 89.23% after 8 h of immersion in a corrosive environment after the addition of 12 mg•mL −1 of BTA-HMSN/ZIF-8-MNZ nanocapsules. Meanwhile, the Q235 steel maintains a smooth and uniform surface with the protection of BTA-HMSN/ZIF-8-MNZ nanocapsules. Overall, the combination of MNZ bactericides and BTA corrosion inhibitors greatly strengthens the antimicrobial and corrosion inhibition performance of the nanocapsules, and this kind of intelligent sulfide ion-responsive protective system also provides insights for retarding MIC in a complex corrosive environment.
