Figure S1 Photographic view of Mogao Grottoes and damaged paintings. A) taken by Charles Nouette of Paul Pelliot Archaeological Expedition in 1908; B) by Zhijun Sun of Dunhuang Academy in 2009; C) and D) exhibited the darkened and microbial contaminated paintings(provide by Dunhuang Academy). Figure S2 Phylogenetic tree of bacterial 16S rDNA sequences derived from the samples of the Mogao Grottoes. Bootstrap values represent 1000 replicates, and only values greater than 50% arereported.The scale bar represents 0.05 substitutions per base position. Figure S3 Phylogenetic tree of fungal ITS sequences derived from the samples of the Mogao Grottoes. Table S1 The culturable bacteria community under different temperatures and their origins. Table S2 The culturable bacteria community under different pH values and their origins. Table S3 The culturable bacteria community under different salinities and their origins.
