[ES]Las tumbas de la Necrópolis Romana de Carmona experimentan diversos grados de deterioro. En su interior, el biodeterioro se manifiesta como biofilms verdes de cianobacterias y algas, así como pequeñas manchas, más localizadas, de diversos colores, de procedencia bacteriana. En el Mausoleo Circular, varias manchas violetas atribuidas a una cepa de Streptomyces productora de pigmentos se monitorizaron a partir de una serie multitemporal de fotografías que abarcaba desde 1997 a 2005. La aplicación de análisis de imagen basado en el Análisis de Componentes Principales permitió la detección espacial de áreas de crecimiento de las manchas, que fueron posteriormente cuantificadas. Estos resultados son básicos para la modelización del comportamiento futuro de las manchas.
[EN]The tombs of the Roman Necropolis of Carmona are affected by different deterioration processes. Biodeterioration appears as green cyanobacterial and algal biofilms, and also smaller stains from bacterial colonization. In the Circular Mausoleum several violet stains, produced by a Streptomyces strain were monitored from a multitemporal photographic series ranging from 1997 to 2005. The utilization of image analysis based on Principal Component Analysis allowed the spatial detection of growing areas of the stains, quantified thereafter. These results are of interest for determining a growth pattern.
