“…It is a pioneer organism because of its capacity to grow diazotrophically (Gallon et al, 1991). Moreover, as other members of Oscillatoriales, it is well adapted to extremely low irradiance compared to other filamentous Cyanophyta (Albertano et al, 2000). The presence of Synechococcus and of the closely related Cyanobium bacillare in sampling points 1 and 2 of SC confirms that the average temperature of SC during the year is not particularly low, since this species does not thrive in cold environments (Sakamoto and Bryant, 1999).…”

Campi Flegrei is a large volcanic area situated northwest of Naples, Italy. Two archeological sites, the Sybil's Cave and the Piscina Mirabilis, are artificial caves dug in the yellow tuff and used during antiquity for various purposes. This paper describes for the first time the algal biodiversity of these caves and determines whether environmental factors such as light intensity and humidity are influential in species distribution. A total of twenty-two algal species were identified by molecular methods (18S rDNA); the largest group was Cyanobacteria (eleven species), followed by algae Chlorophyta (six), Rhodophyta (two) and Bacillariophyta (two). Cluster analysis of algal distribution in the caves in relation to light and humidity showed no relevant differences in algal distribution between the two caves. Three different algal groups were identified. The first one includes strains strictly dependent on low humidity, a second cluster was mainly associated with sites where humidity is not a severe constraint, and a third group, mainly represented by filamentous cyanobacteria, is probably dependent on high humidity, since it was detected only at Piscina Mirabilis.

“…Detailed studies carried out on stone surface, mural paintings in rocky indoor environments and subterranean archeological sites (Albertano et al, 2000;Hoffmann, 2002;Albertano & Bruno, 2003;Urzi et al, 2010;Albertano, 2012) also show light as the limiting factor for the growth of these phototrophic biofilms and the only parameter that can be controlled in situ. In this case, it has also been proven that the presence of artificial light with very low intensity provides a suitable environment for the development of phototrophic microorganisms (Albertano, 2012;Bruno & Valle, 2017).…”

The artificial lighting of caves adapted for touristic visits, leads to the appearance and propagation of a complex community of phototrophic organisms known as "lampenflora". Formed mainly by algae and cyanobacteria, they produce the degradation of the colonized substrates and decrease the show value of the caves. This phenomenon became famous worldwide in the 1960s due to the damage caused to the paintings in the Lascaux Cave (France). Since then it has become an issue of serious concern to both managers of show caves and to the international scientific community. Over time, the problem has been approached following two complementary strategies: preventing colonization by the invading organisms or eliminating them once they have become established through the use of chemical products, mainly biocides and strong oxidants. This kind of treatment generates pollutant effluents that can move the problem from the walls of the caves to the groundwater. This paper presents a critical literature review of the problem and the proposed solutions, and emphasizes the need for further study of the optimal doses of treatment chemicals and to develop quantitative methods to determine their effectiveness. .

“…Bacteria and fungi forming the biofilm produce acidic organic compounds as final products, leading to the corrosion of the colonised substrate (Albertano & Urzì, 1999). Value of pH increases as a consequence of photosynthetic activities, inducing a change in the solubility of the mineral substrate and leading to the corrosion of the surface (Albertano et al, 2000).…”
