Influence of sulphate-reducing bacteria on environmental parameters and marine corrosion behavior of Q235 steel in aerobic conditions

Slippery liquid-infused porous surfaces fabricated on aluminum as a barrier to corrosion induced by sulfate reducing bacteria

“…The bare aluminum samples and SLIPS coated samples were sterilized under ultraviolet radiation for 30 min. According to the growth circle of SRB, SRB present high activity after inoculation for 3 days [23]. Thus, sterilized bare aluminum sample and SLIPS sample were vertically immersed into a 3-days-old culture solution to start the experiments, including analyzing the bacterial adhesion, corrosion behavior on test samples.…”

“…To study the inhibition effect of SLIPS to the adhesion of SRB, both bare aluminum and SLPIS-coated aluminum samples are immersed into 200 mL 3-days-old culture solution with SRB, in which, the growth of SRB is in vigorous growth period with approximately 10 7 CFU ml À1 [23]. During the entire test period, a 50 ml freshly sterile culture solution is utilized to replace an equivalent volume of inoculated culture solution every 2 days, to provide sufficient energy for the growth of SRB.…”

The influence of sulphate‐reducing bacteria on heterogeneous electrochemical corrosion behavior of Q235 carbon steel in seawater

“…This potential drop can be measured by SRET and SVET under the assumption of uniform conductivity of solution [16]. However, metabolic activity of microorganisms in inhomogeneous biofilm makes chemical environment near metal surface much different from that in bulk solution, such as ion species, concentration, pH, and oxygen level [17][18][19][20]. In addition, performance of probe tip of both techniques can be affected by absorption of biofilm [13,21].…”

Carbon steel corrosion induced by sulphate-reducing bacteria in artificial seawater: electrochemical and morphological characterizations

“…The impedance represented by the diameter of the semicircle decreased slightly from 7 to 35 days, probably due to the rupture of the biofilm formed on the steel surface. WAN et al [15] proposed that this behaviour could be induced by changes in the microenvironment and in the biofilm, as well as by the corrosion of the steel substrate, that resulted from the decay of the SRB number.…”

“…Currently, researchers are investigating the formation of biofilms on the corrosion of carbon steels using various species of SRB and microbial consortia [12,13,14,15]. In these cases, artificial seawater is the main incubation medium for these bacteria [16].…”
