Some like it on the rocks: mineral-weathering fungi with manifold protective pigments

  • The interface between materials and the environment is populated by microorganisms which organize on surfaces to form specially adapted and resistant microbial associations, so-called biofilms. Surface-bound biofilm growth is associated with substantial secretion of metabolic products that can significantly influence material corrosion. Here, a group of material-inhabiting fungi are presented, which colonize and weather air-exposed materials such as building façades, roofs and solar systems. A selected model fungus is used to carry out genetic and molecular biology experiments, which are microbiologically cutting-edge and allow for the development of novel time-saving techniques for material testing. The degree of material damage under the influence of this model fungus shows a measure of the aggressiveness of the biofilm under defined environmental conditions - and thus explores fundamental components of the interaction between material and biofilm.
