“…While these approaches are effective, they are limited by high cost, maintenance difficulties, environmental pollution, and short service time (Banerjee et al, 2012; Nkuzinna et al, 2014). In our previous study, we demonstrated that some biofilms are able to provide an environmentally friendly, stable, and lasting biomineralized film to inhibit corrosion in a marine environment (Liu et al, 2019). The film is composed of extracellular polymeric substances (EPS) and calcium carbonate with a calcite structure, exhibiting a stable and self-healing anti-corrosion activity.…”

The marine bacterium, Vibrio natriegens , grows quickly in a marine environment and can significantly accelerate the corrosion of steel materials. Here, we present an approach to inhibit V. natriegens -induced corrosion by biomineralization. The corrosion of steel is mitigated in seawater via the formation of a biomineralized film induced by Bacillus subtilis . The film is composed of extracellular polymeric substances (EPS) and calcite, exhibiting stable anti-corrosion activity. The microbial diversity and medium chemistry tests demonstrated that the inhibition of V. natriegens growth by B. subtilis was essential for the formation of the biomineralized film.

“…Biofilms with stratified structure are never uniform and have different thickness and coverage at different positions of the metal surface, as shown in Figure 6A, 8A. There are different trends for bacterial density, bacterial activity and dissolved oxygen concentration with different biofilm thicknesses (Guo et al, 2017; Liu T. et al, 2018; Liu et al, 2019). Additionally, metabolic activity of bacteria in biofilm makes chemical environment near metal surface much different from that in bulk solution, such as ion species, concentration, pH, and oxygen level (Yuan and Pehkonen, 2007; Xu et al, 2013, 2016; Jia et al, 2018).…”

Corrosion of Q235 Carbon Steel in Seawater Containing Mariprofundus ferrooxydans and Thalassospira sp.

Iron-oxidizing bacteria (IOB) and iron-reducing bacteria (IRB) can easily adhere onto carbon steel surface to form biofilm and affect corrosion processes. However, the mechanism of mixed consortium induced carbon steel corrosion is relatively underexplored. In this paper, the adsorptions of IOB ( Mariprofundus ferrooxydans, M. f. ), IRB ( Thalassospira sp., T . sp.) and mixed consortium ( M. f. and T . sp.) on surface of Q235 carbon steel and their effects on corrosion in seawater were investigated through surface analysis techniques and electrochemical methods. Results showed that local adhesion is a typical characteristic for biofilm on surface of Q235 carbon steel in M. f . and mixed consortium media, which induces localized corrosion of Q235 carbon steel. Corrosion rates of Q235 carbon steel in different culture media decrease in the order: r M.f. > r mixed consortium > r T . sp. > r sterile . The evolution of corrosion rate along with time decreases in M. f. medium, and increases then keeps table in both T . sp. and mixed consortium media. Corrosion mechanism of Q235 carbon steel in mixed consortium medium is discussed through analysis of surface morphology and composition, environmental parameter, and electrochemical behavior.

“…have demonstrated that Bacillus subtilis spores can survive the simulated Mars surface environment (Cortesão et al ., 2019). Bacillus is also reported to cause metal corrosion (Rajasekar and Ting, 2010; Xu et al ., 2013; Karn et al ., 2017; Liu et al ., 2019). Another isolated operational taxonomic unit (OTU) Pseudomonas is also found to cause metal deterioration (Abdolahi et al ., 2014).…”

Corrosion of aluminium (Al) is a potential problem for spacecraft as this metal is used for various mechanical parts due to its strength, durability, etc. However, it can be corroded by certain factors including microbes. Studying microbes which can be implicated in microbiologically influenced corrosion (MIC) due to their extremophilic nature is of vital importance. In this current study, Al and acid-tolerant microbes were isolated from the samples of China space station assembly cleanroom surfaces; acidic environments can accelerate the corrosion process on metal surfaces. Nine bacterial and 10 fungal strains were identified with 16S ribosomal RNA gene/internal transcribed spacer region sequencing and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. The dominant bacteria were of Bacillus, fungi of Penicillium and Aspergillus genera. Knowing the microbes which may be conveyed from the cleanrooms to the space stations with a potential capacity of Al degradation is important for long-term maintenance of station components. This study might aid in designing further researches of the aforementioned microorganisms and, therefore, contribute to the prevention of MIC.
