Re-Identification of Aspergillus Subgenus Nidulantes Strains and Description of Three Unrecorded Species From Korea

Abstract

: Aspergillus subgenus Nidulantes with nine section forms the second largest subgenus of the fungi that comes under the genus Aspergillus. Species in this group of fungi are important as they are reported to play several important roles in the environment including influencing air quality in confined spaces, food spoilage, production of mycotoxins as well as in human pathogenicity. In the present study, 53 strains of Aspergillus subgenus Nidulantes (section: Nidulantes & Usti ) isolated from Korea and preserved at the Korean Agricultural Culture Collection (KACC) were subjected to re-identification by using a combined dataset of partial β-tubulin ( BenA ), Calmodulin ( CaM ) gene sequences as well as their morphological data. We confirmed 14 species from 53 isolates in Korea. Of them, eleven species were reported in Korea previously ( A. amoenus , A. baeticus , A. calidoustus , A. creber , A. insuetus , A. jensenii , A. nidulans , A. protuberus, A. sydowii , A. tabacinus and A. unguis ), and three species ( A. griseoaurantiacus , A. puulaauensis and A. sublatus ) were previously unreported from Korea. We detailed the characteristic features of these three species, that remain unexplored in Korea.

Comparative Bioremediation of Tetradecane, Cyclohexanone and Cyclohexane by Filamentous Fungi from Polluted Habitats in Kazakhstan

“…The genus Aspergillus, already described in 1729 [45], comprises more than 400 species. This number is constantly increasing, and the genus has been repeatedly taxonomically revised over the years [46][47][48][49][50][51][52][53][54], which also explains the variety of studies of this genus on the biodegradation of alkanes. Due to these facts, it is only possible to consider a selected part of this work in connection with our results on the strain Aspergillus sp.…”
