摘要
置于自然环境中的石质文物因物理、化学及生物等因素作用风化腐蚀、开裂破损而处于濒危境地,许多传统方法在应用中或因负面效应太强或因收效甚微而受局限。对结构修复加固应避免造成不可逆反应,其产物应兼具良好的相容性、有效性与耐久性,生物修复加固因应而生。综述了近年来生物修复加固方面的研究进展,并探讨了生物修复加固机理及应用研究前景。
An exposed historic stone is subjected to deterioration and weathering action influenced by various physical, chemical and biological damage factors. Some cultural relics are in severe danger for the weathering and degradation of the surface layer. Numerous conservation treatments have been applied to the protection and reinforcement of it. Most of them, however, either have negative impacts during curing or show very little efficacy. It is necessary that the remediation and reinforcement is achieved without the introduction of material causing irreversibly damage to historic stones. Thus the bioremediation is introduced. This paper provides a comprehensive overview of the bioremediation of cultural stones and stresses practical significance for the conservation.
