Cold-active molecules for a sustainable preservation and restoration of historic-artistic manufacts
2016
In the last decades biotechnology research provides sustainable alternatives to traditional procedures for preventive preservation of cultural assets. Recently, bioactive molecules (BMs) isolated from marine invertebrate organisms have been isolated and tested for bioremoval of protein layers (BMP) or to controlling microbial colonization (BMA), acting at temperature lower than 30°C. The Protease or Antimicrobial activity was tested on ad hoc assembled specimens and on different historic-artistic manufacts. In bio-removing protocol BMP molecules were applied as gelled solutions, in order to guarantees a selective action, respectful of constitutive materials and manufact integrity. Peculiari…
Plant extracts to control microbial growth: a “green” potential strategy
2016
growth process and vegetative development have a direct consequence on the conservation of cultural assets. Recently, due to the use of many chemical compounds applied in biodeteriogens growth control, the attention has been focused on the risks resulting from these treatments that may affect human health (operators, visitors) and the environment. In order to develop alternative methods to traditional biocides, several studies have been focused to various natural products with potential antimicrobial activity, particularly against fungi and bacteria associated with the biodeterioration of cultural assets (Borrego et al., 2012; Sakr et al., 2012; Guiamet et al., 2008). In this study, antimic…
