AbstractTerrestrial and aquatic environments are inhabited by phototrophic microorganisms that include cyanobacteria, green algae and diatoms. These microorganisms have a global significance in the deterioration of cultural heritage stone materials emphasized by their photoautotrophic nature, which permits them to be primary colonizers of lithobiontic ecological niche (Golubic et al. 1981). They develop forming phototrophic biofilms which can be described as surface attached microbial communities driven by light energy with a clearly present photosynthesizing component (Roeselers et al. 2008). In such biofilms, microorganisms use structural irregularities of the stone material for their ATTACHMENT, modifying the stone surface structure.
