Fungi and Stone Heritage Conservation: Friend, Foe, or a Bit of Both [PDF]
Journal of FungiThe presence of lithobionts has historically been associated with biodeterioration, posing significant challenges to the conservation of culturally and historically significant stone heritage. This perception stems from abundant evidence of their role in

Phosphate-based treatments for conservation of stone
RILEM Technical Letters, 2017 To overcome the limitations of currently available protectives and consolidants for carbonate stones (such as marble and limestone), in 2011 the use of calcium phosphate was proposed. The idea is forming calcium phosphates (ideally hydroxyapatite) as the
