인간의 삶에 큰 영향을 끼치는 Aspergillus, Penicillium 및 그들의 완전세대 속에 속하는 곰팡이의 국내 보고 종 목록을 작성하였다. 기존의 국가 생물종 목록집에는 Aspergillus 14종, Eurotium 4종, Neosartorya 8종, Penicillium 47종, Talaromyces 5종이 보고되었다. 본 논문에서는 국제조류 균류 식물명명규약(ICN)에 따른 일균일명 체계에 따라 Eurotium과 Neosartorya은 Aspergillus 속으로 합치고 Penicillium과 Talaromyces도 새로운 속 개념에 따라 정리하였다. 또한 기존의 국가 생물종 목록에 빠져 있던 77종을 추가하여 Aspergillus, Penicillium 및 그들의 완전세대에 속하는 곰팡이의 국내 보고 종 목록을 Aspergillus 55종, Penicillium 82종, Talaromyces 18종으로 정리하였다.

Four strains of Penicillium and Talaromyces species are described and illustrated in an inventory of fungal species belonging to Eurotiales. The strains, CNUFC-DDS17-1, CNUFC-DDS27-1, CNUFC-PTM72-1, and CNUFC-YJW3-31, were isolated from soil and freshwater samples from South Korea. Based on their morphological characteristics and sequence analyses by the combined b-tubulin and calmodulin gene, the CNUFC-DDS17-1, CNUFC-DDS27-1, CNUFC-PTM72-1, and CNUFC-YJW3-31 isolates were identified as Penicillium pasqualense, Penicillium sanguifluum, Talaromyces apiculatus, and Talaromyces liani, respectively. The designated strains were found to represent a previously undescribed species of Korean fungal biota. In this study, detailed morphological descriptions and phylogenetic relationships of these species are provided.

Talaromyces is a genus within the phylum Ascomycota (class Eurotiomycetes, order Eurotiales, family Trichocomaceae). Many species in this genus are known to produce diverse secondary metabolites with great potential for agricultural, medical, and pharmaceutical applications. During a survey on fungal diversity in the genus Talaromyces in Korea, six strains were isolated from soil, indoor air, and freshwater environments. Based on morphological, physiological, and multi-locus (ITS, BenA, CaM, and RPB2) phylogenetic analyses, we identified five previously unrecorded species in Korea (T. brevis, T. fusiformis, T. muroii, T. ruber, and T. soli) and a new species (T. echinulatus sp. nov.) belonging to section Talaromyces. Herein, detailed descriptions, illustrations, and phylogenetic tree are provided.

Two new fungal species of the genus Talaromyces, Talaromyces purpurogenus and Talaromyces trachyspermus from the Trichocomaceae family, were recovered during an investigation of fungal communities in soil collected from the Gangwon-do and Jeollanam-do provinces of Korea. These two species have not been previously officially reported from Korea. In this study, detailed descriptions of internal transcribed spacer rDNA and beta-tubulin gene regions of these two fungi are presented. Morphological features of the two fungi in five agar media, potato dextrose, oatmeal, malt extract, czapek yeast extract, and yeast extract sucrose, are also reported. The species were identified on the basis of molecular and morphological analysis, and herein we present data with detailed descriptions and figures.

Hepatitis B virus is the leading source of liver disorders and is a global health problem and needs advancements in its treatment against increasing problems. Recently five vanitaracin derivatives were isolated from the fungus Talaromyces species which have anti-Hepatitis B virus activity. Hence, in the present study, molecular docking was carried out with five vanitaracin derivatives isolated from Talaromyces species and three known inhibitors.The objective of this work is to study the interaction of newly isolated compounds and compare its interaction with known inhibitors. The docking results revealed that vanitaracin derivatives have good interactions and has better docking score with the Hepatitis B virus and suggest SER2, SER4 and ASP30 are important residues involved in interaction with the inhibitors. These result authenticates vanitaracin derivatives contributes to inhibitory activity of Hepatitis B virus to treat liver disorders.

In order to elucidate the fungal diversity and community structure in freshwater environments, numerous fungal strains were isolated from freshwater, submerged soils, twigs, dead insects, etc. Among them, the present study has focused specifically on Aspergillus, Penicillium, and Talaromyces species, which produce diverse useful metabolites in general. Twelve strains of Aspergillus isolated were identified as A. japonicus (n = 5), A. tubingensis (3), A. niger (2), and A. flavus (2), 10 strains of which belong to Aspergillus section Nigri, named black Aspergillus. Eight strains of Penicillium were identified as P. brasilianim (n = 3), P. oxalicum (2), P. crustosum (1), P. expansum (1), and P. piscarium (1). Two different strains of Talaromyces were identified as T. pinophilus and T. versatilis. Thus far, Penicillium piscarium and Talaromyces versatilis have been unrecorded in Korea, for which we provide detailed morphological and molecular characteristics.

Talaromyces halophytorum sp. nov. was isolated from the roots of halophyte Limonium tetragonum collected from Seocheon-gun, Korea in November 2015. It showed a slow growth on yeast extract sucrose agar at 25 ℃, no growth at 4 ℃ or 37 ℃ and produced smooth-walled and globose to sub-globose conidia. T. halophytorum is phylogenetically distinct from the other reported Talaromyces species of section Trachyspermi based on multi-locus sequence typing results using partial fragments of β-tubulin, calmodulin, ITS, and RNA polymerase II genes.

During fungal diversity surveys of the order Eurotiales in Korea, two fungal strains, EML-DG33-1 and EML-NCP50, were isolated from samples of rat dung and fig tree leaf collected at a garden located in Gwangju in 2014. To complete the National Species List of Korea, it is a prerequisite to verify whether many questionable species, which were previously recorded but not confirmed, indeed present in Korea. Herein, the isolates were confirmed as undescribed species, Paecilomyces variotii and Talaromyces amestolkiae based on the combination of morphological and phylogenetic analyses of multigenes including the rDNA internal transcribed spacer, ${\beta}-tubulin$, and RNA polymerase II subunit 2.

두가지 열처리법에 의한 균 분리방법을 사용하여, 보통균을 제외한 토양균의 분리와 그의 논토양중의 수직 및 계절별 분포를 파악하기 위하여 역곡동과 신원동의 논토양을 시료로 사용하였다. $42^{\circ}C$에서 2일간 배양후 $37^{\circ}C$로 배양하는 방법과 $70^{\circ}C$에서 15분간 열처리하는 방법을 사용하였다. $42^{\circ}C$ 배양법에서는 두 장소에서 분리된 토양균은 거의가 mesophile이었으며 thermotolerant fungi는 Asergillus fumigatus, thermophile로는 Sporotrichum thermophile과 Malbranchea pulchella var. sulfrea이었고, 이들 중 우점종은 Asergillus fumigatus이었다. 두 장소에서 9속, 14종이 분리동정되었으며 Sporotrichum thermophile, Talaromyces ucrainicus, Malbranchea pulchella var. sulfrea는 한국 미기록 종이다. $72^{\circ}C$ 열처리방법으로 분리한 경우 두 장소에서 10속, 20종이 분리동정되었으며, 분리된 균은 거의가 mesophile이었으며 thermotolerant fungi는 Asergillus fumigatus이었고, 우점종은 Talaromyces stipitatus이었다. 또한 Talaromyces helicus var. major, Emericella nidulans var. nidulans, Chaetomium subspirale, Neosartorya fishiri var. fischeri는 한국 미기록 종이다. 두가지 분리방법으로 분리된 토양균의 계절적 분포는 여름과 봄이 가을과 겨울보다 높았으며, 전체 균의 수와 우점종 균수, 그리고 나타나는 종의 빈도는 그 수직분포에 있어서 상층에서 가장 높았으나 하층으로 내려갈수록 감소하였다.
