“…This moisture-controlling function of lichens was confirmed in a study carried out on the microflora colonizing the stone of Angkor Wat and other Cambodian temples [30,113]. The biodeterioration effects on minerals were demonstrated, nevertheless, the measurements of the capillary water uptake showed that lichens protect stone from rapid water uptake whereas cyanobacterial biofilm increases it.…”

This review elucidates current knowledge on the significant role of fungi and lichens in the biodeterioration of stone monuments. The effect caused by many epilithic lichen species in the deterioration of different types of stone has been extensively investigated and demonstrated. Nonetheless, many aspects of the deterioration mechanisms of microcolonial fungi (MFC) and endolithic lichens are still to be proved. An interesting hypothesis has recently been put forward involving the secretion of siderophores like compounds. Lichens can provide bioprotection for stone surfaces, acting as a barrier against weathering, retaining moisture, increasing waterproofing, reducing thermal stress and erosion, and absorbing pollutants. Nevertheless, the evaluation of biodeterioration vs. bioprotection cannot be generalised, since it can vary according to the behaviour of different species, as well as being affected by both the lithotype and the environment. In addition to the laboratory studies, more field studies of biological communities are required, to analyse their establishment and succession in natural conditions and after conservation treatments. In order to guarantee the best decision for stone conservation, cleaning operations should not be based on a generalised approach, but should rather be based on a careful evaluation of different aspects concerning biodeterioration and bioprotection.

“…With regard to the conservation of the Khmer temples, some authors [21][22][23][24], however underlines the positive effects of forest cover and of the biological colonization in stabilizing the microclimate, preventing the negative effects of overheating and ventilation, and regulating moisture on the sandstone. The importance of a better knowledge of the relations among forest canopy and biodeterioration pattern was emphasized in a previous contribution [25].…”
