  • Fungal species belonging to the genus Penicillium are indigenous to a wide range of natural environments. Since the first published reports detailing the discovery of Penicillium, new species have been identified in various countries, including Korea. We present here a full characterization of five species of Penicillium that were previously unreported in Korea. Based on the morphologic characteristics and sequences of genes encoding fungal ��-tubulin and calmodulin, we identified five Penicillium species, including P. hetheringtonii, P. sublectaticum, and P. jacksonii, which have been unrecorded in Korea, and confirming P. maximae and P. cremeogriseum, as the endophytic fungi isolated in Gyeongsang province, Korea. In this article, we provide detailed morphological descriptions of these fungal species.

  • The purpose of this study was to isolate and identify wild yeasts from soil collected in Daegu City and Cheongyang County, Republic of Korea. Among 11 strains isolated in this study, nine strains were previously reported and two strains were unreported in Republic of Korea. To identify wild yeast strains, pairwise sequence comparisons of the D1/D2 region of the 26S rRNA gene sequence were done using Basic Local Alignment Search Tool (BLAST). The cell morphologies were observed by phase contrast microscope and assimilation test are done using API 20C AUX kit. All strains were assigned to the phylum Basidiomycota. Of the two unrecorded yeast strains, CY-9-10C belongs to the genus Mrakia (family Mrakiaceae, order Cystofilobasidiales, class Tremellomycetes) and PG3-4-10C belongs to the genus Slooffia (family Chrysozymaceae, order Microbotryomycetes incertae sedis, class Microbotryomycetes). Both strains had oval-shaped and polar budding cells. This research described the morphological and biochemical properties of the two unreported yeast species that had not officially reported in Korea.

  • The purpose of this study was to isolate and identify wild yeasts from soil samples collected in Daegu and Cheongju city, Republic of Korea. To identify the wild yeast strains, pairwise sequence comparisons of D1/D2 region of the 26S rRNA gene sequence were done using Basic Local Alignment Search Tool (BLAST). The cell morphologies were observed by phase contrast microscope and assimilation test are done using API 20C AUX kit. All strains were assigned to the phylum Basidiomycota. Among 13 strains, 11 strains were previously reported, but two strains were unreported from the Republic of Korea. The two unrecorded yeast strains, GW1-3 and PG1-1-10C, belong to the genus Solicoccozyma (family Piskurozymaceae, order Filobasidiales, class Tremellomycetes). The two strains had oval-shaped and polar budding cells. This research showed the morphological and biochemical properties of the two unreported yeast species that had not officially reported in Korea.

  • As a result of the research project 'Survey and excavation of Korean indigenous species' to secure unrecorded species in Korea, a total of 14 unreported bacterial strains assigned to the phyla Deinococcus-Thermus and Bacteroidetes were isolated from various environmental habitats all around Korea. On the basis of 16S rRNA gene sequence similarity and affiliation to the clade with the closest species, it was concluded that the isolates represent deep groups of the phyla Deinococcus-Thermus and Bacteroidetes. There have been no records about these 14 unreported species in Korea; therefore 2 species of 2 genera in the class Deinococci within the phylum Deinococcus-Thermus, and 11 species of 9 genera in the class Flavobacteriia and one species in one genus in the class Sphigobacteriia within the phylum Bacteroidetes are described as unreported species found in Korea. Gram staining reaction, morphological and other biochemical characteristics are described in the species description section.

  • A total of 34 species belonging to 11 families and 21 genera in the Order Mestostigmata are reported from the Korean Peninsula, of which 20/34 species are new for the fauna of the Korean Peninsula (Lasioseius furcisetus Athias-Henriot, 1959, Cheiroseius nepalensis Evans & Hyatt, 1960, Cheiroseius curtipes (Halbert, 1923), Hypoaspis imitatus Reitblat, 1963, Hypoaspis presternalis Willmann, 1949, Hypoaspis kargi Costa, 1968, Pseudoparasitus placentulus (Berlese, 1887), Gamasiphis novipulchellus Ma & Yin, 1998, Parholaspulus bregetovaae Alexandrov, 1965, Parholaspulus paradichaetes Petrova, 1967, Neparholaspis arcuatus Petrova, 1977, Neparholaspus simplex Evans, 1956, Parholaspulus excentricus Petrova, 1967, Gamasholapis asiaticus Petrova, 1967, Veigaia carpillaris Tseng, 1994, Veigaia anmashanensis Tseng, 1994, Leptogamasus bicorniger Witalinski, 1977, Neogamasus insignis (Holzman, 1969), Iphidinychus kakumeiensis Hiramatsu & Hirschmann, 1992, Trigonuropoda sanguinea Hirschmann & Hiramatsu, 1977). A total of 19 of the previously unreported species were collected in soil samples from the Democratic People's Republic of Korea (DPRK), while 13 species were collected from soil samples from the Republic of Korea (ROK). Only two species were found in both the DPRK and the ROK. Illustrations and short descriptions for previously unreported species provided.

  • In 2019, as a subset study to discover indigenous yeast species in Korea, a total of 20 yeast species were isolated from soil samples collected in Pochoen-si. Among them, eight strains were unreported species. From the high 26S rRNA gene sequence similarity and formation of a robust phylogenetic clade with the closest species, it was determined that each strain belonged to independent and predefined yeast species. The 20 strains were assigned to the genera Aureobasidium (1 strain) and Meyerozyma (1 strain) of the phylum Ascomycota and Cystofilobasidium (2 strains), Filobasidium (1 strain), Naganishia (2 strains), Bullera (3 strains), Leucosporidium (9 strains) and Sampaiozyma (1 strain) of the phylum Basidiomycota. There is no official report of the following species in Korea: Leucosporidium creatinivorum (4 strains), Leucosporidium escuderoi(2 strains), Leucosporidium golubevii(1 strain) and Leucosporidium intermedium (2 strains). Basic biochemical characteristics, colony and cell morphology are also described in the species description section.
