【摘要】：本研究利用FA-I型便携式空气微生物采样器和分子技术,对魏晋五号壁画墓保存环境空气中可培养细菌和真菌的浓度、粒径分布、群落组成进行了监测和分析。结果表明:墓室内外空气中细菌、真菌微粒浓度差异极显著。分子鉴定与系统发生分析显示,墓室内外主要细菌类群组成相似,而真菌类群组成具有较大差异。放线菌、枝孢属、青霉属和链格孢属等大量存在于墓室空气中,成为威胁砖壁画保存的重要污染源。墓室内长期较高的相对湿度和较为封闭的保存环境,是引起小粒径微生物增殖的关键因素。建议阶段性地打开展览厅大门,增加墓室内外的空气交流。
[Abstract]:In this study, FA-I portable air microorganism sampler and molecular technique were used to monitor and analyze the concentration, particle size distribution and community composition of culturable bacteria and fungi in the air of the tomb of Wei Jin 5 fresco.The results showed that the concentration of bacteria and fungal particles in the air inside and outside the tomb was significantly different.Molecular identification and phylogenetic analysis showed that the composition of the main bacterial groups in and out of the tomb was similar, but the composition of fungal groups was different.Actinomycetes, Schizosporium, Penicillium and Alternaria are found in the air of tombs, and have become an important source of pollution that threatens the preservation of brick murals.High relative humidity and closed preservation environment are the key factors of microorganism proliferation.It is suggested to open the exhibition hall door in phases to increase the air exchange inside and outside the tomb.
