|Abstract: ||The microbiota present in public buildings - fungal, algae and fungi that thrive in
buildings and in their construction materials - influence the structural condition as well
as, potentially, the health of those who live, work, or visit them. These organisms can
colonise and deteriorate all kinds of construction materials such as stone, wood, bricks,
glass, steal and metals, concrete, ceramics, tiles, among others. One of the vehicles that
helps to spread and therefore contributes to this biological contamination is the air and
its microbiome in such environments.
In this work we analysed the fungal air burden existing in the cloister of the Old
Cathedral of Coimbra, in four chapels and the central square of this cloister, in two
differentseasons. This allowed relating the fungal air burden with the established fungal
communities (mycobiota) that were present in biodeteriorated spots on the walls of the
studied chapels, in the context of a previous work from our research team.
The fungal air burden was higher in the summer, although with lower diversity. Patterns
of distribution varied between sites, but in general, the most abundant species were
found present in both the central square and chapels, suggesting that the air flows
between these places are likely to vector the exchange of fungal propagules. Moreover,
some less frequent species were found specific to particular chapels, and were not found
in the air samples from the central square.
These findings support the idea of the specificity and environmental requirements of
most retrieved isolates, while showing that the chapels have the potential to host a large
set of organisms that are not present elsewhere. Many of these fungi are linked to
biodeterioration phenomena of the walls and/or are associated to pathogenic and
toxigenic effects in humans.
This study highlights the relevance of assessing the microbiota that thrive in such
settings, and how the design and architecture can influence the composition of the
