Biodeteriorarion designates the physical and chemical alterations resulting from the biological activity that takes place on a surface. The communities of microorganisms associated to biodeterioration grow as biofilms that adhere to the substrates. The treatment used for control of the problems related to biodeterioration and biofouling in materials of patrimonial value are based on avoiding or diminishing the formation of biofilms. The biocides used for these purposes are chemical agents that are mostly toxic; many are difficult to degrade and persistent in the environment. An increasing interest exists for the regulation of the indiscriminate use of toxic chemical compounds. Natural products with biocidal activity, obtained from plants, represent an alternative and useful source in the control of biodeterioration, without negative environmental impacts. The aim of this work was to evaluate the antimicrobial activity of different aqueous, acetonic, and ethanol extracts of Cichorium intybus L., Arctium lappa L., Centaurea cyanus L. (Asteraceae), Allium sativum L. (Liliaceae), Pinus caribea Mor. (Pinaceae), Eucalyptus citriodora Hook. (Mirtaceae) and Piper auritum Kunth (Piperaceae) against different microorganisms associated with biodeterioration. The results of the extracts obtained are described and analyzed, and the potential value of these natural products in the control and prevention of biodeterioration is discussed.
