Abstract

Debate on whether biofilms on stone monuments are biodeteriorative or bioprotective is long-standing. We propose a criterion of 'relative bioprotective ratio' for assessing the ambivalent role of the biofilms by comparing biodeterioration with weathering. A boundary between biodeterioration and bioprotection exists and fluctuates with dynamic microflora influenced by environmental conditions.

摘要

关于石质纪念碑上的生物膜是生物降解还是生物保护,一直存在争议。我们提出了一个“相对生物保护比”的标准,通过与风化作用相比来评估生物膜的矛盾作用。生物降解和生物保护之间存在一个界限,并随着受环境条件影响的动态微生物群落而波动。
