Accepted 23rd April, 2012
Two hundred paintings of Filipino masters, all accessioned at
the UST Museum of Arts and Sciences, were surveyed to determine
their state of preservation. Forty-three (21.5%) oil paintings
were found to be in different states of deterioration with mold
attack as the most common cause. Fungal infestations were most
evident on pigments, wood support and paper backing. The
infested paintings, based on the records at the museum, are
between 50 and 100 years old. Infesting molds were isolated by
swab method and purified through a series of transfer in plates
of Malt extract agar (MEA) with pH 3.5 and incubation
temperature of 280C. Forty-eight isolates in six genera as
follows were obtained and identified based on cultural and
morphological characteristics in MEA: Aspergillus and
Penicillium (Deuteromycota); Rhizopus, Mucor and Cunninghamella
(Zygomycota); and Chaetomium (Ascomycota). Aspergillus is the
most prevalent with 77% occurrence in all the paintings sampled.
It is followed by Penicillium, 13%, and then Chaetomium sp., 4%.
The lesser isolates wherein each has an occurrence rate of 2%
are Mucor, Cunninghammella, and Rhizopus.
