Culturable fungi associated with urban stone surfaces in Mexico City
Background: Urban surface stones in Mexico City are exposed to a
temperate climate and a range of atmospheric conditions ranging from
mildly impacted to heavily polluted areas. In this study, we focused on
the characterization of the cultivable fungal component of selected
biological patinas in the surrounding area of Chapultepec castle, a
historic monument in Mexico City. Thirty four representative fungal
isolates selected based on distinctive differential macroscopic
characteristics out of a total of 300 fungi, were characterized using
morphological and molecular approaches. Results: This identification
strategy based on the combination of phenotypic- and molecular-based
methodologies allowed us to discriminate the fungal community in some
cases down to the species level. Conclusions: The characterization of
this mycoflora revealed the presence of a complex fungal community
mainly represented by filamentous fungi belonging to the genera
Fusarium , Trichoderma , Aspergillus , Cladosporium , Alternaria ,
Mucor , Penicillium , Pestalotiopsis , and the dimorphic fungus
Aureobasidium , along with the yeast Rhodotorula . A specific
distribution of fungi could be observed based on the type of biological
patina analyzed
