The aim of this thesis was to present a new discovery in the scientific world which is the bacterium Halomonas Titanicae. Beyond being an incredible microorganism resisting to extremes conditions, it represents a hope for the science regarding its properties of “chewing” the iron and the steel. However, due to its irreversible activity, it represents a danger for the conservation of the UNESCO heritage which wanted to keep the Titanic wreckage intact. Finally, considering the actions of the bacterium upon the iron and the steel, it would be interesting to study the eventual applications concerning the cleaning of the seas and oceans.
This report gives different points of views of this new bacterium, causing so many debates, to understand what it is so special, and how it represents a challenge for the scientific and the cultural world.
The thesis is divided in six main sections including the introduction giving general information about the subject of this thesis to have some basis before getting into the report. The second chapter gives information about the bacterium to understand where it comes from, to detail its structure and biological activity. The third chapter is about the reaction occurring at the bacteria – iron interface. The corrosion is a natural phenomenon which can damage structures, but it exists different forms of corrosion. In this report, the aqueous corrosions and the microbiologically influenced corrosion will be studied more deeply. The next section deals with the experiments that could have been done. It was to show the influence of different factors (environmental conditions, microorganisms) on the corrosion rate to overcome how the Titanic could disappear by 2030. The fifth chapter is about all the different applications possible concerning the bacterium, the issue it caused regarding the Titanic future, and all the unanswered interrogations concerning Halomonas Titanicae.
It is important to study the nature and the mysteries of this bacterium because in some cases, it is possible to apply the properties for good purposes such as the cleaning of the Earth which is polluted by humans: it is called biomimetic. Understanding the biological process of organisms is a clever way to cope with the environmental issues and impacts around the world.
