“…Earlier studies in Cuba have reported similar results from museums, archives and libraries at the University of Havana , in storage areas containing mostly cellulose-based materials such as the National Archive (Vaillant et al, 1989, Borrego et al, 2008, on photographic materials (Borrego et al, 2010) and inside churches (Sánchez et al, 1988) and homes (Aira et al, 2002). Research in other parts of the world has also highlighted the prevalence of Aspergillus, Penicillium and Cladosporium as well as Alternaria in religious buildings (Aira et al, 2007) and their effect on frescoes (Nugari & Roccardi, 2001) and historical documents (Robledo & Moretti, 1986) has been documented. Studies in modern buildings with problems of damp have stressed the adverse effects of Penicillium on wood and inorganic material and of Penicillium and Cladosporium on paper (Hyvärinen et al, 2001).…”
