“…In the current study, the sprayed HDTMS on the calcium carbonate surface filled in the defects and penetrated the inner calcium carbonate layer. This resolved some of the shortcomings of the biomineralized film for anti-corrosion applications, greatly improving their anti-corrosion potential and application scope ( Liu et al, 2018 ; Guo et al, 2021 ). Moreover, the improved hardness and roughness of the calcium carbonate layer also improved the mechanical properties and hydrophobicity of the HDTMS layer.…”

“…As a microorganism with the capacity for ammonification, B. subtilis can decompose proteins and various nitrogen-containing organic substances to ammonium ions (NH + ) and bicarbonate (HCO – ), effectively, increasing the pH of the medium ( Hoffmann et al, 1998 ). Biomineralized films have some advantages that other rough surfaces normally lack, such as anti-corrosion, anti-wear, and strong adhesion ( Guo et al, 2021 ). Our previous work showed that the biomineralized crystal induced by Pseudoalteromonas lipolytica and B. subtilis exhibited trapezoidal pillars with a hierarchical structure with micro- and nano-scale features ( Liu et al, 2018 ).…”

The fabrication of an eco-friendly, multi-functional, and mechanically robust superhydrophobic coating using a simple method has many practical applications. Here, inspired by shell nacre, the micro- or nano-scale surface roughness that is necessary for superhydrophobic coatings was formed via Bacillus subtilis–induced mineralization. The biomineralized film coated with hexadecyltrimethoxysilane (HDTMS) exhibited superhydrophobicity with water contact angles of 156°. The biomimetic HDTMS/calcite-coating showed excellent self-cleaning, anti-icing, and anti-corrosion performances. Furthermore, mechanically robust superhydrophobicity could be realized by hierarchically structured biomineralized surfaces at two different length scales, with a nano-structure roughness to provide water repellency and a micro-structure roughness to provide durability. Our design strategy may guide the development of “green” superhydrophobic coatings that need to retain effective multi-functional abilities in harsh marine environments.

“…Pitting corrosion is different in the initiation stages, whereas crevice corrosion is initiated by a differential change in concentration of oxygen or ions surrounding the electrolyte [25][26][27], where the material alone initiates pitting. Microorganisms, in theory, could, therefore, enhance pitting corrosion in terms of their excretion products, which causes further and subsequent degradation to the material [28][29][30]. Further pits ensue across the surface of the material, where the natural pitting process will continue to propagate.…”

Almost every abiotic surface of a material is readily colonised by bacteria, algae, and fungi, contributing to the degradation processes of materials. Both biocorrosion and microbially influenced corrosion (MIC) refer to the interaction of microbial cells and their metabolic products, such as exopolymeric substances (EPS), with an abiotic surface. Therefore, biofouling and biodeterioration of manufactured goods have economic and environmental ramifications for the user to tackle or remove the issue. While MIC is typically applied to metallic materials, newly developed and evolving materials frequently succumb to the effects of corrosion, resulting in a range of chemical reactions and transport mechanisms occurring in the material. Recent research on biocorrosion and biofouling of conventional and novel materials is discussed in this paper, showcasing the current knowledge regarding microbial and material interactions that contribute to biocorrosion and biofouling, including biofilms, anaerobic and aerobic environments, microbial assault, and the various roles microorganisms’ play. Additionally, we show the latest analytical techniques used to characterise and identify MIC on materials using a borescope, thermal imaging, Fourier transform infrared (FTIR), atomic force microscopy (AFM), scanning electron microscopy (SEM), X-ray photoelectron microscopy (XPS), X-ray diffraction (XRD), optical and epifluorescence microscopy, electrochemical impedance spectroscopy, and mass spectrometry, and chemometrics.

“…However, few studies have shown biomineralisation by this bacterial genus. Recently, Pseudoalteromonas lipolytica was studied to protect steel from corrosion in seawater via the formation of a biomineralised film [57,58]. The hybrid biofilm was composed of multiple layers of calcite and extracellular polymeric substances (EPS), exhibiting high and stable barrier-protection efficiency.…”

New Biocalcifying Marine Bacterial Strains Isolated from Calcareous Deposits and Immediate Surroundings

Marine bacterial biomineralisation by CaCO3 precipitation provides natural limestone structures, like beachrocks and stromatolites. Calcareous deposits can also be abiotically formed in seawater at the surface of steel grids under cathodic polarisation. In this work, we showed that this mineral-rich alkaline environment harbours bacteria belonging to different genera able to induce CaCO3 precipitation. We previously isolated 14 biocalcifying marine bacteria from electrochemically formed calcareous deposits and their immediate environment. By microscopy and µ-Raman spectroscopy, these bacterial strains were shown to produce calcite-type CaCO3. Identification by 16S rDNA sequencing provided between 98.5 and 100% identity with genera Pseudoalteromonas, Pseudidiomarina, Epibacterium, Virgibacillus, Planococcus, and Bhargavaea. All 14 strains produced carbonic anhydrase, and six were urease positive. Both proteins are major enzymes involved in the biocalcification process. However, this does not preclude that one or more other metabolisms could also be involved in the process. In the presence of urea, Virgibacillus halodenitrificans CD6 exhibited the most efficient precipitation of CaCO3. However, the urease pathway has the disadvantage of producing ammonia, a toxic molecule. We showed herein that different marine bacteria could induce CaCO3 precipitation without urea. These bacteria could then be used for eco-friendly applications, e.g., the formation of bio-cements to strengthen dikes and delay coastal erosion.
