Abstract
Reported are the main findings of an investigation aimed at the breakdown and decolourisation of black micro-fungal debris embedded in the modem acrylic paint of a wooden Australian Aboriginal object. Results of experiments for the enzymatic breakdown of this fungal debris using gels containing chitinase, glucanase and protease enzymes are presented. Further testing of selected reagents for the decolourisation of melanin, the source of the black pigmentation in the fungi is described. The application of atypical enzymes to a convex acrylic paint surface and the resilience of the fungal pigment melanin is discussed.
