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.
