 Affect the fruition
 Produce serious deterioration mechanisms
- Mechanical damage by hyphae or algal filament growths
- Increase of water absorption
- Chemical actions such as chelation or leaching of minerals driven by the
production of specific substances.

Un eccellenza
anche da un punto di vista industriale, perchè riesce a far parlare mondi diversi:
ricerca, Universita', grande impresa e laboratori artigianali.
