本研究的目的是选择有效和安全的杀微生物剂，用于前奥斯威辛集中营的历史木制表面的消毒和保护。我们测试了七种抗细菌和霉菌的活性化合物，其中二癸基二甲基氯化铵和N-（3-氨基丙基）-N-十二烷基丙烷-1，3-二胺即使在0.02%-2%时也是有效的。随后，选择含有所选活性成分的八种杀微生物剂，并在细菌和霉菌定植的木材样品表面上施用三次。ABM-1和ABM-2-6%溶液、Rocima 101-8%、R80 -12%、Acticide 706 LV-15%和Boramon-30%是最有效的消毒剂。在实验室条件下，ABM-1、Boramon和Rocima 101可确保新木材样品的抗菌保护达6个月。在现场，30%的Boramon和8%的Rocima 101通过喷涂有效地保护了历史木材的细菌和霉菌的生长分别为12个月和3个月。新木材的颜色和亮度在暴露于杀生物剂后没有改变。Boramon和Rocima 101通过喷涂方法施用，对历史木材的颜色没有造成显著变化。从这项研究的结果被用来开发一个程序，保护木材在历史建筑物的生物退化。
The aim of this study was to select effective and safe microbiocides for the disinfection and protection of historical wooden surfaces at the former Auschwitz II-Birkenau concentration and extermination camp. We tested seven active compounds against bacteria and moulds, of which didecyldimethylammonium chloride and N-(3-aminopropyl)-N-dodecylpropane-1,3-diamine were effective even at 0.02%-2%. Subsequently, eight microbiocides containing the selected active ingredients were chosen and applied three times on the surface of wood samples colonized by bacteria and moulds. ABM-1 and ABM-2-6% solution; Rocima 101-8%; Preventol R 80-12%; Acticide 706 LV-15% and Boramon-30% were the most effective disinfectants. Under laboratory conditions, ABM-1, Boramon and Rocima 101 ensured antimicrobial protection of new wood samples for six months. In situ, 30% Boramon and 8% Rocima 101 applied by spraying effectively protected the historical wood from bacterial and mould growth for 12 and 3 months, respectively. Colour and luminance of the new wood were not altered after exposure to the biocides. Boramon and Rocima 101, applied by the spraying method, caused no significant change in the colour of the historical wood. Results from this study were used to develop a procedure for the protection of wood in historical buildings against biodeterioration.
