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.
