Abstract[EN]: Due to the limitation of nutrients during long periods, deteriorated monuments, and particularIy their walls, represent an interesting ecosystem where oligotrophic bacteria can be isolated. Therefore, facultatively oligotrophic bacteria, present in the deteriorated mural paintings decoratíng the Tomb of Servilia, Roman Necropolis of Carmona, 1st and 2nd century AD, were studied. The most abundant genera were Bacillus and Paenibacillus, which were also the most abundant copiotrophs. Total celIular fatty acid methyl esters were analysed· and a cluster analysis was performed. It was shown a close relationship between copiotroph and oligotroph isolates, as the copiotroph iso lates resulted to be facultatively oligotrophs.
[ES]: Se han estudiado las comunidades microbianas presentes en las pinturas murales de la Tumba de Servilia, Necrópolis de Carmona, siglo I-II A.e. Se ha detectado la presencia de bacterias oligotrofas facultativas. Entre las bacterias copiotrofas o heterotrofas, los géneros más abundantes fueron Bacillus y Paenibacillus, que también resultaron ser los más abundantes entre las bacterias oligotrofas. Debido a la limitación de nutrientes los monumentos y, particularmente sus paredes, representan un interesante ecosistema que permite el aislamiento de bacterias oligotrofas.
