- Marine biomineralization for enhanced corrosion resistance: Insights from the ANR MICOATEC project [Poster]Publication . Marques, Maria João; Nkoua, C.; Jaume, Julien; Diderot, Anthony; Mercier, Dimitri; Seyeux, Antoine; Délia, Marie-Line; Silva, S. da; Fori, B.; Blanc, C.; Zanna, Sandrine; Marcus, Philippe; Basseguy, RegineABSTRACT: Concerns about marine pollution and ecological threats caused by traditional corrosion protection technologies have driven the development of new environmentally friendly anti-corrosion solutions. In recent years, it became clear that microorganisms have the potential to positively impact corrosion behavior, a phenomenon known as MICI (microbiologically influenced corrosion inhibition) [1,2]. Although research on MICI mechanisms is still in the beginning, two main mechanisms have been outlined: direct and indirect inhibition. In the first one, the microorganisms are responsible for the segregation of slow-release inhibitors or surfactants or consume oxygen, which affects the cathodic reaction process. The second one, indirect inhibition mechanism, is associated to the formation of a protective layer on the surface of the material due to metabolic activity of microorganisms. In this context, biomineralization attracted the attention of researchers as a solution to inhibit metal corrosion.
- Marine Microbial Induced Mineralization: Exploring Mechanisms for Bioinspired Anticorrosion solutionsPublication . Marques, Maria João; Zanna, Sandrine; Marcus, Philippe; Basseguy, RegineABSTRACT: In the field of corrosion, nature has proved to be a source of inspiration for developing new green protection concepts. Over the last decades, new emerging microbial-based technologies have been studied, based on the recognition that microorganisms can influence corrosion behaviour in an advantageous way, the so-called MICI (microbiologically influenced corrosion inhibition), opening different lines of research (1-5). In particular, the process of biomineralisation on the surface of materials was recently highlighted as a promising new environmentally-friendly approach to produce protective coatings.
