While often considered as harmful for cultural heritage, microorganisms can also be used for its safeguarding. The methods used so far for the conservation-restoration of cultural heritage are often unsatisfactory in terms of efficiency and durability. Inhibitors or complexing agents are also toxic and pose potential threats to human health and to the environment. Microbial-based technologies can provide sustainable solutions for heritage conservation-restoration using ecologically friendly biological treatments. Over the last decades, the development of biological methods and materials has become a significant alternative for the preservation of ancient heritage. Of particular note, microbial metabolisms are exploited to consolidate, clean, stabilize or even protect surfaces of cultural items. Taking advantage of unique properties of microorganisms, reactive corrosion products are extracted or converted into biogenic minerals that provide the treated surfaces with long-term stability. Examples of the techniques proposed include the formation of passivating biogenic layers that can be applied for preservation of metal-based heritage, as well as the development of methods for the preventative removal of iron species from waterlogged wood. This review presents the current advance made in research aiming to preserve copper- and iron-based artefacts, in particular sculptures but also archaeological objects, as well as in the development of a method for the extraction of iron species from waterlogged wood.

应用于濒危金属和木材遗产物体的代谢过程:呼叫微生物管道工!

虽然通常被认为对文化遗产有害,但微生物也可用于保护文化遗产。迄今为止,用于文化遗产保护和修复的方法在效率和持久性方面往往不尽如人意。抑制剂或络合剂也有毒,对人类健康和环境构成潜在威胁。基于微生物的技术可以使用生态友好的生物处理为遗产保护-修复提供可持续的解决方案。在过去的几十年里,生物方法和材料的发展已成为保护古代遗产的重要替代方案。特别值得注意的是,微生物代谢被用来巩固、清洁、稳定甚至保护文化物品的表面。利用微生物的独特特性,反应性腐蚀产物被提取或转化为生物矿物,为处理过的表面提供长期稳定性。提议的技术示例包括形成可用于保护金属基遗产的钝化生物层,以及开发方法以预防性去除浸水木材中的铁。本综述介绍了当前在保护铜基和铁基文物的研究方面取得的进展,特别是雕塑和考古物品,以及从浸水木材中提取铁物种的方法的开发。反应性腐蚀产物被提取或转化为生物矿物,为处理过的表面提供长期稳定性。提议的技术示例包括形成可用于保护金属基遗产的钝化生物层,以及开发方法以预防性去除浸水木材中的铁。本综述介绍了当前在保护铜基和铁基文物的研究方面取得的进展,特别是雕塑和考古物品,以及从浸水木材中提取铁物种的方法的开发。反应性腐蚀产物被提取或转化为生物矿物,为处理过的表面提供长期稳定性。提议的技术示例包括形成可用于保护金属基遗产的钝化生物层,以及开发方法以预防性去除浸水木材中的铁。本综述介绍了当前在保护铜基和铁基文物的研究方面取得的进展,特别是雕塑和考古物品,以及从浸水木材中提取铁物种的方法的开发。以及开发从浸水木材中预防性去除铁物种的方法。本综述介绍了当前在保护铜基和铁基文物的研究方面取得的进展,特别是雕塑和考古物品,以及从浸水木材中提取铁物种的方法的开发。以及开发从浸水木材中预防性去除铁物种的方法。本综述介绍了当前在保护铜基和铁基文物的研究方面取得的进展,特别是雕塑和考古物品,以及从浸水木材中提取铁物种的方法的开发。
