Towards understanding the link between the deterioration of building materials and the nature of aerophytic green algae.

The gradual degradation of technical materials by bacteria, cyanobacteria and fungi, is of great economic and social significance. In temperate climates, microbial colonization is associated with phototrophic eukaryotes, predominantly aerial green algae. However, these phototrophs are able to colonize most substrates in all terrestrial environments, regardless he geographical area.
