Abstract: | Library collections kept under bad climatic conditions are subject to microbial destruction mainly being
attacked by mold and fungi. The paper becomes brittle, porous, and consequently the chemical changes
resulting in the depolymerization of cellulose, disintegrates and the holes are formed in the paper. The assessment
of microbiological hazards was carried out on the selected collection: ”Rozwiazanie Piącidziesiat
y dwu Quęstiy Ministrow Nowoewangelickich, Iezuitom zadanych … – Wszystko znowu … przeyrzano.
– y powtore wydano” from the Library collection of the Wiktor Foundation hr. Baworowskiego in Lviv.
This collection showed traces of microorganisms through visible discoloration, stains, stains, dirt. The
microbiological examination consisted of squeezing the sterile tissue of the pages of the pages and book
covers that were the most vulnerable to the mycelium. The paper was transferred to the Petri dishes with
the base according to the Hat and Sabouraud. Samples were incubated at 24°C for 14 days and then the
mycelium species was determined. Epoxiconazole of appropriate concentration was used as a new generation
of disinfectant using a separator method, ie a paper soaked with solution, and every 20 sheets of paper
were transferred. The book was placed in foil and left for 14 days. After this time, mycelium was tested
again. The analysis showed no mycelium spores. Epoxiconazole proved effective fungicide. Safe for man,
environment and paper. |
