Cyanobacteria, green algae and diatoms are significant factors in the biodeterioration of
stone cultural heritage sites, and specifically fountain monuments, due to the constant presence of
water. In this study, samples were taken from di erent fountains in the Alhambra and Generalife,
which are among the Spanish monuments of greatest historical and artistic value and which together
were declared a World Heritage Site by UNESCO in 1984. The aim was to identify which species
of colonising microalgae are most frequent and to obtain monoalgal cultures from them. From a
conservation point of view, it is interesting to identify which algae are growing in these fountains and
how they behave in order to develop new methods to control their growth. The most abundant groups
of algae in our samples were green algae and cyanobacteria. The most common genera in the former
group were Bracteacoccus, Chlorosarcina, Chlorosarcinopsis, Apatococcus and Klebsormidium. As for
cyanobacteria, the most abundant genera were Phormidium, Calothrix, Leptolyngbya, Chamaesiphon,
Pleurocapsa and Chlorogloea. Using our collected samples, 10 genera of green algae and 13 genera of
cyanobacteria were isolated, thereby constituting the base samples for the creation of a reference
collection of living algae from the Alhambra and Generalife contexts, which can be used in subsequent
studies to develop new types of treatment against biodeterioration.
