| Research Abstract |
This study aimed to investigate the microbial diversity which was involved in the biodeterioration of murals in the Takamatsuzuka Tumulus. To elucidate the cause of biodeterioration, we carefully identified using an integrated analysis of phenotypic and genotypic characters. The major bacterial isolates were also identified at the generic level using the same methodology. As a result, the major fungal taxa relating to biodeterioration of murals were assignable to Fusarium solani species complex, some Trichoderma spp., Acremonium (sect. Gliomastix) masseei and Penicillium paneum. Some Candida and Pichia and bacterial species in addition to molds species were involved in the formation of biofilms on plaster walls. The selected isolates and their DNA sequences determined in this study were deposited in the public culture collection and public gene bank, respectively.
