The scientific multistep approach described herein is a result of two years of research into a control method against microbial fouling and biodeterioration of historic building materials by phototrophs. A series of tests were conducted to select the best antifouling agent for eliminating 'green' coatings and protecting surfaces against biofouling. Of the seven active compounds, two with the best penetration abilities were subjected to a photosynthetic activity inhibition test using confocal microscopy. Of the two, a quaternary ammonium salt (QAC) - didecyldimethylammonium chloride (DDAC) - was found to be the most effective. Ten biocides containing QACs at different concentrations were then tested against 'green' coatings on wood, brick and plaster, with the best four being selected for further research in model conditions. As a result, biocides containing >14% (v v) DDAC were found to be successful antifouling agents for protecting historical materials against biodeterioration by phototrophs.
本文所描述的科学多步骤方法是对光养生物对抗微生物污垢和历史建筑材料生物降解的控制方法进行了两年研究的结果。进行了一系列测试以选择最佳的防污剂来消除“绿色”涂层并保护表面免受生物污垢的侵害。在七种活性化合物中，选择了两种具有最佳渗透能力的化合物，并用共聚焦显微镜进行了光合作用活性抑制测试。在这两种化合物中，发现季铵盐（QAC）-二癸基二甲基氯化铵（DDAC）最为有效。然后，对含有不同浓度 QAC 的十种杀生物剂进行了针对木材、砖和灰泥上“绿色”涂层的测试，选择了最好的四种在模型条件下进行进一步研究。结果发现，含有>14%（v/v）DDAC 的杀生物剂是保护历史材料免受光养生物生物降解的成功防污剂。
