Three species of Ellobiid molluscs collected from Korea were identified as Auriculastra duplicata (Pfeffer, 1854), Laemodonta siamensis (Morelete, 1875) and Melampus (Pira) flavus (Gmelin, 1791). This is the first record from the Korea, providing a description of the species with illustration for the shell morphology. Including the new recorded in this study, the family Ellobiidae contained six genera and 13 species in the Korea.

Based on the taxonomic survey to uncover the ciliate diversity in the eastern Kangwon-province, twenty-six species were identified from moss-covered soils and assigned to 5 classes, 9 orders, 12 families, and 15 genera. Of these, fifteen species are first records from Korea, and brief remarks with photographs were provided.

More than five hundreds of yeast species (including 9 variants) encompassing 142 genera and 48 classes of 2 phyla exist in Korea. However, only 173 species have been cataloged in the National Species List of Korea (NSLK), the backbone reference to claim sovereign rights over biological resources, as of December 2021, due to the lack of taxonomic descriptions, although some of these species are extensively used in industry. The present pilot study investigated the taxonomy of strains belonging to the six most widely used or frequently isolated yeast species (Meyeromyma guilliermondii, Saccharomyces cerevisiae, Saccharomycopsis fibuligera, Wickerhamomyces anomalus, Candida tropicalis, and Papiliotrema flavescens) to include these species in the NSLK. Strains with diverse habitats and geographic origins were retrieved from the National Institute of Biological Resources culture collection. These strains clustered in the same clade as the type strains of the designated species according to phylogenetic analysis of the D1/D2 sequences. Moreover, we described the cell morphology and physiological characteristics of representative strains of each species. This study suggests that these six species are indigenous to Korea and can be accordingly listed in the NSLK.

Penicillium, the most common genus plays an important ecological role in various terrestrial and marine environments. However, only a few species have been reported from rhizosphere soil. As part of a project to excavate Korean indigenous fungi, we investigated rhizosphere soil of six plants in the forest (terrestrial habitat) and sand dunes (coastal habitat) and focused on discovering Penicillium species. A total of 64 strains were isolated and identified as 26 Penicillium species in nine sections based on morphological characteristics and the sequence analysis of β-tubulin and calmodulin. Although this is a small-scale study in a limited rhizosphere soil, eight unrecorded species and four potential new species have been identified. In addition, most Penicillium species from rhizosphere soil were unique to each plant. Penicillium halotolerans, P. scabrosum, P. samsonianum, P. jejuense, and P. janczewskii were commonly isolated from rhizosphere soil. Eight Penicillium species, P. aurantioviolaceum, P. bissettii, P. cairnsense, P. halotolerans, P. kananaskense, P. ortum, P. radiatolobatum, and P. verhagenii were recorded for the first time in Korea. Here, we provide the detailed morphological description of these unrecorded species.

In July 2018, solar saltern samples were collected from Siheung, Gyeonggi-do Province to obtain unrecorded haloarchaea in Korea. The samples were suspended in a 20% NaCl (w/v) solution, and serial dilution was performed in fresh DB Characterization media No. 2. The strains isolated in this study showed at least 98.7% sequence similarity or more compared to the previously reported. Finally, 16 haloarchaeal strains, which were not reported in Korea but validly published under the International Code of Nomenclature of Prokaryotes (ICNP), were obtained from a solar saltern in Siheung. These 16 isolates were allocated to the orders Halobacteriales and Haloferacales. The 10 Halobacteriales strains were classified into the family Halobacteriaceae and Haloarculaceae. Each family belonged to three genera, respectively. The other six Haloferacales belonged to the families Haloferacaceae and Halorubraceae. Each family belonged to genus genus, respectively. Collectively, the unrecorded haloarchaeal strains belonged to two orders, four families, and eight genera. During the research, the possibility of discovering previously unknown species in domestic solar saltern was established. Gram-staining, cell morphology, physiological and basic biochemical parameters, and phylogenetic analysis were all performed in this study and are described in detail for each strain.

We report Najas orientalis Triest & P. Uotila and N. oguraensis Miki as unrecorded species from the Korean flora. N. orientalis is distinct from other Najas species in having rounded leaf sheaths and raised testa in the cell walls, and in that this species occurs in the southern region of Korea (Gimhae, Gangjin). N. oguraensis is close to N. minor, but is distinct from this species by having larger male flowers and 4-celled anthers. This species is distributed in the southern region of Korea (Changwon, Jangheung). We also give a new Korean common name for N. gracillima (A. Braun ex Engelm.) Magnus, which is widely distributed in South Korea. A taxonomic key to the six species of Najas is given.

Three species of endosymbiotic dinoflagellates, zooxanthellae, are investigated from six host species of anthozoans from Korea. Three unrecorded endosymbionts species are Symbiodinium kawagutii, Symbiodinium microadriaticum, and Symbiodinium sp. Symbiodinium kawagutii Is associated with Alveopora japonica, Anthopleura japonica and Parasicyonis actinostoloides. Symbiodinium microadiraticum is found in Anthopleura kurogane and Parasicyonis sp. Unlike the former two symbionts, Symbiodinium sp. is associated with Anthopleura midori.

Ten species of paramecia have been recorded up to the present , but there has been no report on paramecium in Korea. With the purpose of taxonomical study, paramecia were collected as materials at the several areas(ponds and streams) in Seoul from the first of March to the late of October , 1962. From the characteristics of the body-shape and the type and number of micronuclei, the six unrecorded species are identified on this paper as follows : Paramecium caudatum P.aurelia P.multimicromucleaturm P.bursaria P.trichium P.calkinsi

The fungi play important roles in maintaining the balance and homeostasis of natural ecosystems. We investigated fungal specimens indigenous to the Gayasan National Park located in the deep inlands of southeastern Korea from 2017-2020. Six fungal species in the Korean macromycota-Chiua olivaceoreticulata, Entoloma conchatum, Galerina sulciceps, Hebeloma radicosoides, Spongiporus gloeoporus, and Tricholoma sinoacerbum-were identified based on morphological characteristics and rDNA sequences. The six fungal speices were newly revealed on the Korean Peninsula, and it supports that the continuous investigaton is the best way to realize the mycosis.

In 2020, 24 bacterial strains were isolated from algae, kudzu leaf, mud, pine cone, seashore sand, sea water, soil, tidal flat, and wetland from the Republic of Korea. Isolated bacterial strains were identified based on 16S rRNA gene sequences, and those exhibiting at least 98.7% sequence similarity with known bacterial species, but not reported in Korea, were highlighted as unrecorded species. These isolates were allocated to the phyla Bacteroidetes and Proteobacteria as unrecorded species in Korea. The four Bacteroidetes strains were classified into the families Chitinophagaceae, Flavobacteriaceae, and Sphingobacteriaceae (of the orders Chitinophagales, Flavobacteriales, and Sphingobacteriales, respectively). The 20 Proteobacteria strains belonged to the Aeromonadaceae, Marinobacter, Microbulbiferaceae, Enterobacteriaceae, Erwiniaceae, Morganellaceae, Yersiniaceae, Lysobacteraceae, Halomonadaceae, Moraxellaceae, Pseudomonadaceae, Steroidobacteraceae, Xanthomonadaceae, and Myxococcaceae (of the orders Aeromonadales, Alteromonadales, Cellvibrionales, Enterobacterales, Lysobacterales, Oceanospirillales, Pseudomonadales, Steroidobacter, Xanthomonadales, and Myxococcales). This study focused on the description of 24 unreported bacterial species in Korea in the phyla Bacteroidetes and Proteobacteria belonging to six classes.
