New life found in ancient tombs

25.09.2008
Life has been discovered in the barren depths of Rome's ancient tombs, proving catacombs are not just a resting place for the dead.

The two new species of bacteria found growing on the walls of the Roman tombs may help protect our cultural heritage monuments, according to research published in the September issue of the International Journal of Systematic and Evolutionary Microbiology.

The Catacombs of Saint Callistus are part of a massive graveyard that covers 15 hectares, equivalent to more than 20 football pitches. The underground tombs were built at the end of the 2nd Century AD and were named after Pope Saint Callistus I. More than 30 popes and martyrs are buried in the catacombs.

"Bacteria can grow on the walls of these underground tombs and often cause damage," said Professor Dr Clara Urzì from the University of Messina in Italy. "We found two new species of bacteria on decayed surfaces in the catacombs and we think the bacteria, which belong to the Kribbella group, may have been involved in the destruction."

By studying bacteria that ruin monuments, the researchers hope to develop methods of protecting cultural heritage sites such as the catacombs in Rome. The two new bacterial species discovered in the tombs also have the potential to produce molecules that have useful properties, like enzymes and antibiotics.

"The special conditions in the catacombs have allowed unique species to evolve," said Professor Dr Urzì. "In fact, the two different Kribbella species we discovered were taken from two sites very close to each other; this shows that even small changes in the micro-environment can lead bacteria to evolve separately."

Kribbella species are found in many different locations all over the world, from a racecourse in South Africa to a medieval mine in Germany. The genus was only discovered in 1999 but since then several species have been found. The two species discovered in the Roman catacombs have been named Kribbella catacumbae and Kribbella sancticallisti.

"The worldwide existence of the genus Kribbella raises questions about the path of evolution," said Professor Dr Urzì. "If the bacteria are very old, does the wide geographical distribution prove the genus is stable? Or have similar bacteria evolved in parallel to one another in different places? The questions are made even more interesting by the discovery of these two different bacteria in the Roman tombs."

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
