Halomonas titanicae is a gram-negative, bacilli shaped bacterium from strain BH1T. It’s –×– μm in size. It’s a motile microorganism. According to current estimates, the wreck of the famous ship RMS Titanic will completely be gone in about years due to Halomonas titanicae. The wreck is covered with rusticles; the knob-like mounds have formed from at least 27 strains of bacteria, including Halomonas titanicae.

Name and taxonomic classification. In their article these researchers give information regarding the bacterium’s cell structure, size, metabolism, genome, and the niche it inhabits. In the south Pacific regional ocean there is approximately 3, sunken war vessel including battle ships, tankers, oilers and air craft carriers.

Due to its environment this bacterium is difficult to grow under laboratory conditions. Although other species of bacteria are found in the rusticles with H.

Information on culture and growth conditions Culture and growth conditions. Information on isolation source, the sampling and environmental conditions Isolation, sampling and environmental information. The haloomnas which the H. In the 25 years since the discovery of the wreck, the Titanic has rapidly deteriorated.

Halomonas titanicae

Only first 10 entries are displayed. Metabolite utilization Metabolite Utilization activity Kind of utilization tested [Ref.: A Microbial Biorealm page on the genus Halomonas titanicae.

Researchers at Dalhousie University in Halifax, Nova Scotia, in Canada have been examining the bacteria eating away at the remains of the famous ship as it sits on the ocean floor.

In some ways that’s a little sad because the world is losing a part of its history, but in other ways it is kind of cool that the Earth has developed a way of recycling itself to this extent, obtaining energy from the most unlikely places. While some Halomonas strains have been shown to infect humans, currently there is no known evidence that H.

The iron-oxide-munching bacterium has fittingly been named Halomonas titanicae. Rusticles are porous and allow water to pass through; they are rather delicate and will eventually disintegrate into fine powder. It is, however, hazardous to metals, specifically those which contain high levels of rust due to its ability to deteriorate these man made structures [2,3,6].


Further research is currently being performed on the Halomonas genus and new bacteria are being discovered daily. Using DNA technology, Dalhousie scientists Henrietta Mann and Bhavleen Kaur and researchers from the University of Sevilla in Spain were able to identify a new bacterial species collected from rusticles a formation of rust similar to an icicle or stalactite from the Titanic wreck.

The bacteria have critical implications for the preservation of the ship’s wreckage.

Halomonas titanicae sp. nov., a halophilic bacterium isolated from the RMS Titanic.

It is an extreme halophile salt loving with peritrichous flagella for motility [2]. For the science geek in everyone, Live Science offers a fascinating window into the natural and technological world, delivering comprehensive and compelling news and analysis on everything from dinosaur discoveries, archaeological finds and amazing animals to health, innovation and wearable technology.

Research is still being conducted to determine of other species in the rusticles contribute to the degradation of the metal as well. Additionally it is really interesting that something as small as a Halomonas titanicae bacterium could basically destroy something so titanicaw and historically momentus as the Titanic.

For decades following the ship’s sinking inthe Titanic ‘s final resting spot remained a mystery. Information on morphological and physiological properties Morphology and physiology. Although a tragedy to the Titanic, this new bacterium can be utilized to recycle the metal on other sea wrecks sitting idle on the ocean floor.

This bacterium collects on the side of metal surfaces, and was discovered on the ship the RMS Titanic. Live Science Staff, on. Scientists indicate that in just a few more decades the wreck of the RMS Titanic will be no more.

The idea that there is a living organism promoting rust at extremely low temperatures seems hard to believe since these living conditions are harsh. Further, it could also help scientists develop paints or protective coatings to guard against the bacteria for working vessels. Catalase as well as oxidase are produced. The need ofr regional collaboration to address the potential marine pollution threat.


Inscientists had thought the structure of the titanic would last 30 more years. Information on possible application of the strain and its possible interaction with e. Discovered by a joint American-French expedition inthe wreck is located a little more than 2 miles 3. Personal tools Log in. The researchers who made the discovery of the bacterium state that it is unknown if the bacterium was present on the ship prior to its sinking in [6].

As a chemo-organotrophic organism its metabolism is respiratory. StrainInfo introduces electronic passports for microorganisms.

Halomonas titanicae sp. nov., a halophilic bacterium isolated from the RMS Titanic.

Halomonas titanicae halomoonas a gram-negative, bacilli shaped bacterium from strain BH1T. It is a psychrotolerant mesophile, it grows best between degrees Celsius but is capable of growth at temperatures as low haomonas 4 degrees Celsius [2]. As an extremophile group, Halomonas bacterium can grow under extreme conditions, high salt concentration, which could become significant in future biotechnological applications and mechanisms [4]. For referencing data from this strain:. Only first 5 entries are displayed.

While the disintegration of the Titanic titanicaw preservation of the ship impossible, the bacteria doing the damage may be useful in accelerating the disposal of other old ships and oil rigs.

Further research on it is difficult because it’s challenging to reproduce colonies in a setting other than its natural habitat.

As of now, there are no reports of disease or infections affecting living organisms, however this titancae is new discovered. Click here to see all. Perhaps if we get another 15 to 20 years out of it, we’re doing good Halomonas titanicae BH1 contig, whole genome shotgun sequence.
