Sensitivity of bacteria and fungi colonising sheets of unbleached cellulose to biocides assigned for protection of archaeological wood in Biskupin / Wrażliwość bakterii i grzybów kolonizujących arkusze niebielonej celulozy na biocydy przeznaczone do ochrony drewna archeologicznego w Biskupinie
Abstract
The paper presents the results of biocidal action of quaternary ammonium salts and other compounds, such as disinfectants, on bacterial and fungal colonisers, isolated from the sheets of unbleached cellulose immersed in aqueous solutions of various disinfectants, kept for two years in the laboratory conditions in Biskupin. The experiments were carried out with an agar disc diffusion method. Bacterial strains colonising cellulose sheets that were in contact with disinfectants were more resistant to these compounds than those isolated from control samples (without contact with disinfectants). Isolated Aspergillus fumigatus and A. niger strains of fungi were resistant to the quaternary ammonium compounds.
