“…The experimental water was prepared according to the quality specifications of the reclaimed water used as circulating cooling water. 20 Chemicals used in synthesizing the experimental water together with their respective concentrations are shown in Table 1 . Three groups of tests were conducted: (1) the samples were in the conventional reclaimed water inoculated with IB, 1Cl IB ; (2) the samples were in the reclaimed water with 3 times the Cl − concentration inoculated with IB, 3Cl IB ; (3) the samples were in the reclaimed water with 4 times the Cl − concentration inoculated with IB, 4Cl IB .…”

“…Average corrosion inhibition rate of Pseudomonas fluorescens for carbon steel is 48.14% in the artificial water environment (Xu et al 2020). P. fluorescens can inhibit the corrosion behavior of carbon steel in reclaimed water, and corrosion rate remains at 0.16-0.18 mm/a (Chu et al 2020). It is found that Pseudomonas has great potential for corrosion inhibition in seawater, reclaimed water and other environment, while seldom is used on carbon steel in the oilfield water.…”

The corrosion behavior of Q235B carbon steel is investigated in water, LB medium and oilfield produced water adding Pseudomonas fluorescens FSYZ01. After immersion for 13-days, weight loss of carbon steel with this strain decreased by 32.23%, 54.07%, and 78.34% respectively. XRD results show Pseudomonas fluorescens FSYZ01 inhibited conversion of iron oxides by hindering oxygen from approaching metal surface. FT-IR and XPS results show that specific functional groups and bonds reacted with Fe(II/III) to form a dense and stable chelate-oxide protective layer, thereby inhibiting corrosion. Py-GCMS results demonstrate the bacteria degraded C12 to C20 alkanes in oil. The inhibitory mechanism of crude oil degrading bacteria Pseudomonas fluorescens FSYZ01 on the carbon steel corrosion was proposed, so as to slowing corrosion of oilfield produced water system pipeline and prolonging its service life, helping to comprehend the microbial corrosion in the actual environment.

“…Based on these studies, bacteria are commonly considered to dramatically affect the formation of corrosion products [19][20][21] . Robert et al 22 described the conversion process from Fe(0) to iron oxide and iron-sulfur compounds under the influence of bacteria.…”

Steel rust layers immersed in the South China Sea with a highly corrosive Desulfovibrio strain

Although it is well known that microbes play a significant role in marine corrosion, few studies have systematically studied the relationship between microorganisms and corrosion products under long-term immersion. In this study, the corrosion characteristics of the rust layer formed on carbon steel immersed in the South China Sea for 5.5 years were investigated using various surface analysis and microbial community analysis techniques. Magnetite (Fe3O4), iron sulfide, and green rust were identified in the inner rust layer. The middle rust layer was composed of maghemite (γ-Fe2O3), and some Fe3O4 and mackinamite were also detected. The outer rust layer contained several Fe(III)-oxyhydroxides, and it had a large number of fouling organisms attached to it. In all of the rust layers, anaerobic sulfate-reducing bacteria (SRB) were the dominant bacteria, and they may have played a key role in the formation of the corrosion products. One SRB strain (Desulfovibrio bizertensis SY-1) with a highly corrosivity (13.561 mg/cm2) was isolated from these rust layers, and its physiological and metabolic characteristics were studied. These results expand the membership of corrosive SRB and establish a better understanding of marine microbiologically influenced corrosion (MIC).
