Experimental assessment of microbial successions following removal of black strain alterations on Paleolithic cave walls
Anthropization of Paleolithic karstic caves cause an imbalance of cave microbiota and may result in formation of wall alterations including black stain. In the Lascaux Cave, previous conservation strategy consists of a mechanical cleaning of the stains and a new black stain started to form in the following months, with the properties as the previous one, suggesting that black stain microbial recolonization was fast.
