“…), were able to dissolve CaCO 3 , which found to be the base material of the Lan Na’s mural painting in this study. The dissolution of this calcium compound may result from secondary metabolite secreting from the microorganism which could cause severe damage to the paint layers ( Čukovska et al, 2017 ). We further found that isolate SK1, Trichaptum sp., was able to form calcium crystals which could further crack the paint layer and deteriorate the painting.…”

“…Biomineralization is the process by which living organisms influence the precipitation of mineral materials ( Skinner and Ehrlich, 2014 ). The formation of salt or calcium compound can also lead to the deconstruction of the painting’s layer, as it could increase the pressure on the mural materials and crack the artwork ( Pérez-Alonso et al, 2004 ; Piñar and Sterflinger, 2009 ; Čukovska et al, 2017 ; Suphaphimol et al, 2022 ). Due to the ability of microorganisms to cause mural deterioration, as described above, it is of utmost importance to observe and investigate the possible threats that these organisms pose to a mural painting.…”

Diverse microorganisms from the three domains of life (Archaea, Bacteria, and Eukaryota) cause deterioration in mural paintings worldwide; however, few studies have simultaneously targeted these three domains. This study aims to survey the microbiome and its potential for biodeterioration on unpreserved Lan Na mural paintings in Sean Khan temple, Chiang Mai, Thailand. The overview of the archaeal, bacterial, and fungal communities was reported by Illumina sequencing, whereas the potential for deterioration was revealed by culturable techniques and a literature search. The abundant microbes reported in this study were also found in other ancient mural paintings worldwide. Halococcus, a salt-tolerant archaeon, as well as the eubacterial genus Crossiella dominated the prokaryotic community. On the other hand, the main fungal group was the genus Candida (Ascomycota). However, a low number of fungi and bacteria were isolated. Most of the isolates showed the ability to survive in the drought conditions of mural paintings but could not perform discoloration activities. The deterioration activity mainly affected calcium compounds, which are the main components of painting substrates. Aspergillus and several bacterial isolates could dissolve calcium compounds, but only Trichaptum species could induce crystal formation. These results suggest that deterioration of painting substrate should be taken into consideration in addition to deterioration of color in mural paintings. For the Lan Na painting in Sean Khan temple, the plaster is the prime target for biodeterioration, and thus we suggest that the preservation effort should focus on this component of the mural painting.
