| Sumario: | Paper works are more attacked by biological agents such as fungi, bacteria and insects due to its organic nature. In archives, most of the biological destruction of paper is related to fungi. The importance of paper works conservation has led to applying different methods to fungus removal. The chemical disinfection is of of the most common disinfection methods. In this research, the application of Thiophanate methyl in paper destructive fungi has been studied. Laboratory studies to evaluate the effects of Thiophanate methyl on paper and fungus include accelerated ageing, the evaluation of effectiveness of antifungal Thiophanate methyl on fungi such as Aspergillusniger, Aspergillusflavus and Penicilliurnsp and determination of antifungal stability after accelerated ageing. Examination shows that Thiophanate methyl has successfully prevented spread of fungus in all density of 10, 50, 100,200 and 500 ppm. Aspergillus flavus fungus had a slight growth at 10 ppm, but no growth were observed in other density. Aspergillusniger fungus had no growth capacity in density more than 100 ppm. According to the results, treated papers are still able to control fungus growth after being in accelerated ageing condition. In general, the results obtained by fungus growth halo and non-growth halo indicate that all fungi are controllable in density of 200 ppm. |
