Biology in art: Genetic detectives ID microbes suspected of slowly ruining humanity's treasures

A new study of the microbial settlers on old paintings, sculptures, and other forms of art charts a potential path for preserving, restoring, and confirming the geographic origin of some of humanity's greatest treasures.

Genetics scientists with the J. Craig Venter Institute (JCVI), collaborating with the Leonardo da Vinci DNA Project and supported by the Richard Lounsbery Foundation, say identifying and managing communities of microbes on art may offer museums and collectors a new way to stem the deterioration of priceless possessions, and to unmask counterfeits in the $60 billion a year art market...

The genetic detectives caution that additional time and research are needed to formally convict microbes as a culprit in artwork decay but consider their most interesting find to be "oxidase positive" microbes primarily on painted wood and canvas surfaces.

These species can dine on organic and inorganic compounds often found in paints, in glue, and in the cellulose in paper, canvas, and wood. Using oxygen for energy production, they can produce water or hydrogen peroxide, a chemical used in disinfectants and bleaches...

The Leonardo da Vinci DNA Project involves scientists in France (where Leonardo lived during his final years and was buried), Italy (where his father and other relatives were buried, and descendants of his half-brothers still live), Spain (whose National Library holds 700 pages of his notebooks), and the US (where forensic DNA skills flourish).

The Leonardo project has convened molecular biologists, population geneticists, microbiologists, forensic experts, and physicians working together with other natural scientists and with genealogists, historians, artists, and curators to discover and decode previously inaccessible knowledge and to preserve cultural heritage.

Who's DNA? The artist or the critic?
