| Popis: | In the last decades, the contribution of different scientific disciplines in the field of restoration and conservation of cultural heritage to finding alternative methods of investigation that are even more effective and fully respect artworks, operators and environment, has greatly increased.An example is the University of Milan patent that provides for the use of some specialized bacteria as cleaning agents. This method, known as biocleaning, is based on the use of Desulfovibrio vulgaris, a sulfate reducing bacterium, for the removal of sulfate alterations from stone surfaces.Recently, the university spin-off Micro4yoU purchased the patent by initiating a series of investments aimed at enhancing the commercial product from prototype. The present work describes: the desulfation mechanism operated by Desulfovibrio vulgaris and the technological shift necessary to obtain a biological formulation usable in situ, with two practical case studies. |
