| Caves are no uniform environments from a geochemical or geological point of view and could be influenced by artificial lighting and the maximum number of daily visitors, in the case of caves with rock art the study of rock art biodeterioration are crucial if we want to mantein this irreplaceable legacy. The study of biodeterioration paintings in caves using culture-independent techniques are scarce. The present report is the results of the application of molecular techniques in the study of two Cantabrian caves (northern of Spain) with rock art, Las Monedas (Puente Viesgo) and Chuf?ªn (Puente Nansa) where have been detected these alterations. The paintings of Las Monedas cave were elaborated in black using as pigment charcoal, while in Chuf?ªn the paintings are red using iron oxide as pigment. Both of them received visitors along the year, the first cave has a system of artificial lighting while in the second the visitors entry only with torchlights, and both present diferent types of colonies growing in the paleolithic rock art. In Las Monedas cave were detected white colonies formed by microorganisms belonging to Actinobacteridae, Chloroflexi, Gemmatimonadaceae, ?Á- and ?Â-proteobacteria, while in Chuf?ªn cave were detected two types of colonies, the yellow ones formed by Actinobacteridae, Acidobacteria, Nitrospirae, Sphingobacteria, ?Á- ?Â- and ?Ã-proteobacteria, and the white ones formed by Actinobacteridae, Acidobacteria, Sphaerobacteria and ?Ã-proteobacteria. The study revealed the Chloroflexi group of microorganisms were identified only in the iluminated cave. Aditionally, different colonies growing in different points of the caves, and not related with the rock art, were analysed using the same techniques, obtaining a great diversity of microorganisms related with microbial populations identified in other caves in Spain and Italy. | |
