Técnicas no destructivas para la monitorización cuantitativa y cualitativa de procesos de biodeterioro en materiales pétreos

Abstract

[ES]: La colonización biológica de la piedra es uno de los principales problemas para la conservación de edificios y monumentos. El biodeterioro de la piedra ha sido estudiado empleando metodologías para la identificación de los microorganismos y para el seguimiento de su acción que, en su mayor parte necesitan de una gran inversión de tiempo y de un muestreo extensivo. Muchos de los procedimientos de muestreo empleados pueden, incluso, convertir a los propios investigadores en agentes de deterioro. En este estudio se propone el uso de técnicas para la detección temprana y monitorización de colonizaciones microbianas sin necesidad de contacto, como manera de contribuir al objetivo de preservar el patrimonio cultural.

[EN]: Biological stone colonisation is one of the main problems related to the conservation of monuments and buildings. Stone biodeterioration has been assessed by several authors using time-consuming and extensive sampling methodologies for microbial identification and the follow-up of their action. However, most sampling procedures may convert the own researchers in deterioration agents. In this study the use of non-contact techniques for early detection and monitoring of microbial colonisations is proposed, as a contribution to the goal of the preservation of cultural heritage.
