Identification and Characterization of Five Previously Unrecorded Penicillium Species of Subgenus Aspergilloides Isolated in Korea

Summary

Researchers in Korea discovered one new Penicillium fungal species and four species that had not been previously recorded in the country. These fungi were found in freshwater and soil samples from five Korean provinces. By analyzing the fungi’s genetic material and physical characteristics, scientists confirmed their identities and added them to Korea’s catalog of fungal species. This research helps create a valuable collection of domestic fungal resources that may have future applications in agriculture and biotechnology.

Background

Penicillium species are widely distributed across various substrates including soil, aquatic habitats, and food products. Korea has reported 160 Penicillium species, highlighting the region’s fungal diversity. However, uncharacterized native species remain to be explored.

Objective

This study aimed to expand the catalog of Penicillium species in Korea’s soils by isolating and identifying fungal strains from freshwater and near-freshwater substrates across five Korean provinces. The research established a valuable resource for future mycological research and biotechnological applications.

Results

One novel species (Penicillium retrofuscum sp. nov.) and four species newly recorded in Korea were identified. Strains were classified as P. ellipsoideum, P. skrjabinii, P. yezoense, and P. pancosmium based on phylogenetic and morphological comparisons with reference strains.

Conclusion

The identification of these Penicillium species enriches Korea’s fungal inventory and provides a basis for valuable future resource development. The findings highlight the need for continued exploration of underrepresented freshwater environments for fungal diversity.
