Identification of microbial taxa involved in cultural heritage deterioration and able to produce health hazardous substances by molecular techniques.

2008

Fungi and bacterial, wide-spread in biosphere environments, are the main microorganisms related to the deterioration of cultural assets but, moreover, complex microbial communities may emit mixed aerosol into indoor air. In this study the microbial colonization is investigated from to point of view, conservation of cultural heritage and related potential illness to visitors or professionals. The sampling was performed by non-destructive procedures on works of art surfaces, and by the gelatin membrane filter method (Sartorius) for aerosol. The identification of microbial taxa was performed by molecular analyses based on PCR, sequencing, sequence comparison techniques and, particularly for fu…
