Abstract

Natural products obtained from plants with biocidal activity represent an alternative and useful source in the control of biodeterioration of documentary heritage, without negative environmental and human impacts. In this work, we studied the antimicrobial activity of seven essential oils against microorganisms associated with the biodeterioration of documentary heritage. The essential oils were obtained by steam distillation. The antimicrobial activity was analyzed using the agar diffusion method against 4 strains of fungi and 6 bacterial strains isolated from repositories air and documents of the National Archive of the Republic of Cuba and the Historical Archive of the Museum of La Plata, Argentina. Anise and garlic oils showed the best antifungal activity at all concentrations studied, while oregano oil not only was effective against fungi tested but also prevented sporulation of them all. Orange sweet and laurel oils were ineffective against fungi. Clove, garlic, and oregano oils showed the highest antibacterial activity at 25% against Enterobacter agglomerans and Streptomyces sp., while only clove and oregano oils were effective against Bacillus sp. at all concentrations studied. This study has an important implication for the possible use of the natural products from plants in the control of biodeterioration of documentary heritage.

从古巴和阿根廷文献遗产中分离的植物精油作为微生物的杀菌剂。
从具有生物杀灭活性的植物中提取的天然产物是控制文献遗产生物退化的另一种有用来源,不会对环境和人类产生负面影响。在这项工作中,我们研究了七种精油对与文献遗产生物变质有关的微生物的抗菌活性。精油是用蒸汽蒸馏法得到的。采用琼脂扩散法对从古巴共和国国家档案馆和阿根廷拉普拉塔博物馆历史档案馆的空气和文献中分离的4株真菌和6株细菌进行抑菌活性分析。在所有浓度下,茴香油和大蒜油的抗真菌活性最好,而牛至油不仅对真菌有效,而且能抑制所有真菌的产孢。甜橙油和月桂油对真菌无效。丁香、大蒜和牛至油对凝集肠杆菌和链霉菌的抑菌活性最高,达到25%,而在所有浓度下,只有丁香和牛至油对芽孢杆菌有效。本研究对利用植物天然产物防治文献遗产生物退化具有重要意义。
