摘　　要：通过对敦煌莫高窟6个洞窟中的51个典型变色颜料样品的微生物检测，发现其中的细菌有6个属，优势菌为芽孢杆菌属和产碱菌属；霉菌有5个属，优势菌为青霉属。将分离得到的菌种，通过模拟试验证明，枝孢霉、黑曲霉和2种特殊细菌对壁画红色颜料变色和胶结材料的老化均起着重要作用。Microbial strains were isolated from 51 typical color changed samples ofmural in 6 grottos of Dunhuang Mogao Gretto. After identification, it is proved thatbelong to 6 genera of bacteria and 5 genera of mould. Bacillus, Alcaligenes andPenicillium were dominant species in all of them. In the imutative experiment it isfound that Cladosporium sp., A. niger and two strains of bacteria have a great effecton the color change of red pigment of mural and aging of sizing agent.
