Sažetak

Cultural heritage items are composed mainly of organic compounds which are susceptible to biodegradation. Various molds species are the most widespread biological agents that cause damage to library materials. Molds that can produce cellulose enzymatic complex, which degrades and damages cellulose, are most dangerous to paper, because cellulose is its main component. Mold spores are constantly present in the air, in the dust and on various objects, and in the favourable conditions the molds will easily develop. The degree of paper susceptibility to mold attack depends on the chemical characteristics of the paper and the environmental conditions in the library. Critical environmental factors, which are favorable for mold growth on paper, are presence of mold spores, source of nutrients, sufficient moisture, appropriate temperature for certain species of mold and limited air circulation. The most important condition for germination of mold spores is moisture. Good hygienic measures and elimination of environmental conditions that can cause mold growth are the best means of prevention of mold attacks. Infected materials have to be isolated, cleaned and disinfected by specified procedures. The most common genera of molds on paper are Chaetomium, Trichoderma, Aspergillus, Penicillium, Stemphylium, Alternaria, Stachybotrys and Cladosporium.
The 47 mold species that are most frequently isolated from paper are systematized in this study.
