Abstract

Eighty-seven strains of Aspergillus section Restricti were isolated from five storage rooms (50 strains) and 21 houses (37 strains) between 2014 and 2020. Eleven species were identified based on their morphological characteristics and molecular phylogeny using the rRNA internal transcribed spacer (ITS) region, calmodulin (CaM), β-tubulin (benA), and RNA polymerase II second largest subunit (RPB2) sequences. A. penicillioides, which was known to cause the deterioration of cultural assets, was isolated at high frequency (73%) from the surfaces of 11 cultural assets in the storage rooms; A. clavatophorus and A. magnivesiculatus, which are closely related to A. penicillioides, were also isolated frequently (45 and 64%, respectively). Five species [A. clavatophorus (42.8%), A. penicillioides (42.8%), A. magnivesiculatus (14.3%), A. reticulatus (28.6%), and A. vitricola (28.6%)] were isolated from dust on the carpets in seven houses. Five species [A. clavatophorus (33.3%), A. penicillioides (55.5%), A. magnivesiculatus (44.4%), A. restrictus (44.4%), and A. gracilis (11.1%)] were isolated from dust on the bedding in nine houses. Using the taxonomic system described by Sklenář et al. (2017), five species (A. clavatophorus, A. magnivesiculatus, A. hordei, A. reticulatus, and A. glabripes) previously identified as A. penicillioides were confirmed as new to Japan.

基于日本仓库和房屋分离的干燥曲霉切片修订系统分类的物种多样性。
2014 - 2020年,从5间储藏室(50株)和21间房屋(37株)中分离出限制性曲霉87株。利用rRNA内部转录间隔区(ITS)、钙调蛋白(CaM)、β-微管蛋白(benA)和RNA聚合酶II第二大亚基(RPB2)序列,根据形态特征和分子系统发育鉴定了11个物种。已知会导致文物变质的盘尼西林霉菌(A. penicillioides),从储藏室的11件文物表面以高频率(73%)分离出来;与青霉菌类群亲缘关系较近的A. clavatophorus和A. magnivesiculatus的分离率也较高(分别为45%和64%)。五种[A];从7户住宅地毯灰尘中分离出锁骨螨(42.8%)、盘青霉螨(42.8%)、大斑螨(14.3%)、网状螨(28.6%)和vitricola螨(28.6%)。五种[A];9间房屋床上灰尘中分别检出击蝽(33.3%)、盘尼青霉蠓(55.5%)、magnivesiculatus(44.4%)、限制蠓(44.4%)和细纹蠓(11.1%)。利用Sklenář et al.(2017)描述的分类系统,先前鉴定为青霉菌属的5种(A. clavatophorus、A. magnivesiculatus、A. hordei、A. reticulatus和A. glabripes)被确认为日本的新物种。
