New species of bacteria found in Titanic 'rusticles'


The Titanic, which hit an iceberg and sank in 1912 and then was found by searchers in 1977, Its not only know for its film made on it and also for Mysteries behind it.
Now Titanic is in news again Proving that it still had mysteries In its chest.

A never-before-seen microbe has been found in the wreck of RMS Titanic which is contributing to its deteroration.



The novel bacterium has been named Halomonas titanicae by the scientists from Dalhousie University, Halifax, Canada and the University of Sevilla, Sevilla, Spain. The team also tested the rusting ability of the bacterium - and found that it was able to adhere to steel surfaces, creating knob-like mounds of corrosion products, which they will be reporting in an upcoming paper in the latest issue of the International Journal of Systematic and Evolutionary Microbiology published on 8 December.


The Halomonas titanicae bacterium was found in “rusticles”, the porous and delicate icicle-like structures that form on rusting iron.
Various bacteria and fungi live within the delicate structures – first identified on the Titanic – actually feeding off the rusting metal.



Samples of rusticles from Titanic were gathered in 1991 by the Mir 2 robotic submersible.

The Researchers sequenced the microbes’ DNA before discovering that they constituted a new member of the salt-loving Halomonas genus.

The bacteria are of particular interest because they may shed light on the mechanism by which rusticles form, and thus on the general “recycling” that such microbes carry out on submerged metal structures.

That, the authors point out, has relevance also to the protection of offshore oil and gas pipelines, and the safe disposal at sea of ships and oil rigs.
