Abstract:

Microbial diversity in lichen (LI) and moss habitats on Leshan Giant Buddha was analysed using high-throughput sequencing to determine the major microorganisms responsible for the biodeterioration of this monument. Bacterial and fungal communities were clustered in the LI, live moss (LM), and dead moss residue (DM) groups. The communities could be distinguished among the three groups. The bacterial communities in LI and LM groups were similar, with the families Cyanobacteria and Acetobacteraceae predominating. The order Capnodiales was the dominant fungal order in the LI group, but it was less abundant in the LM group. Ascomycota was the dominant fungal phylum in the LM group. The relative abundance ranged from 7.47% to 52.6% in the LI and DM groups. The archaeal community markedly differed among LI, LM, and DM groups. The soil Crenarchaeotic group (SCG) related to nitrogen transformation was the most abundant. In addition, large numbers of unclassified-k-norank species were observed across all groups.

Key words: rock heritage, biodeterioration, living moss(LM), lichen(LI), dead moss residue(DM), microorganism, biological treatment
