During a biodiversity survey of undiscovered taxa in Korea, two zygomycetous fungal strains were isolated. The first strain, EML-FSDY6-1 was isolated from a soil sample collected at Dokdo Island in the East Sea of Korea in 2013, and the second strain, EML-DG-NH3-1 was isolated from a rat dung sample collected at Chonnam National University garden, Gwangju, Korea in 2014. Based on the morphological characteristics and phylogenetic analysis of the internal transcribed spacer, 18S and 28S rDNA, actin and translation elongation $factor-1{\alpha}$ genes. EML-FSDY6-1 and EML-DG-NH3-1 isolates were confirmed as zygomycete species, Absidia pseudocylindrospora and Absidia glauca, respectively. Neither species has previously been described in Korea.

During a survey of fungal diversity of the order Mucorales, three zygomycete isolates, CNUFC-YR113-1, CNUFC-KNU16-7, and CNUFC-BS1-1 were isolated from freshwater and soil samples in Korea. The strains were analyzed both morphologically and phylogenetically based on internal transcribed spacer and 28S rDNA gene sequences. Based on their morphology and phylogeny, the CNUFC-YR113-1 and CNUFC-KNU16-7 isolates were identified as Actinomucor elegans, and CNUFC-BS1-1 was identified as Mucor minutus. To the best of our knowledge, the species A. elegans and M. minutus, belonging to an undiscovered taxon, have not been previously described in Korea.

In a survey of undiscovered taxa in Korea, three zygomycete fungal strains-EML-W31, EML-HGD1-1, and EML-RUS1-1-were isolated from freshwater, grasshopper fecal, and soil samples in Korea. On the basis of the morphological characteristics and phylogenetic analysis of internal transcribed spacer and 28S rDNA, the isolates of EML-W31, EML-HGD1-1, and EML-RUS1-1 were confirmed to be Cunninghamella bertholletiae, Cunninghamella echinulata, and Cunninghamella elegans, respectively. These species have not been previously described in Korea.

한국의 논에서 나타나는 토양균류상을 서울근방 두곳 즉 역곡동과 신월동에서 4계절을 통해 채취한 토양표본을 희석평판배지법에 의해 분리했다. 총 85개 순수배양균을 분리했고, 그중 13속, 30종을 동정했다. 동정된 30종중 6종은 불완전 균류로 한국에서 처음으로 이 논문에 기재하였다. 불완전균류중 논토양에 많이 분포되어 있는 것은 대부분이 Penicillium 속이다 그 중 한국에서 처음으로 나타난 종류로는 Penicillium funiculosum, P. piceum, P. roqueforti 그리고 P. verruculosum 등이었다. P. piceum의 경우는 가문비나무같은 상록수와 유사한 전형적인 원추형 분생자루가 현저한 특징을 나타낸다. P. roqueforti는 penicilli가 부정형으로, 빽백하게 분기된 metulae와 밀착 또는 분산상의 phialide를 가지며 stipes는 두텁고 많은 입자를 가진 벽을 형성하고 있다. 그외 Cladosporium cladosporioides, Paecilomyces variotii도 분리되었으며, Zygomycete 중에서는 Zygorhynchus moelleri가 가장 우세하게 분포되어 있는 종으로써 난형 Columella를 가지고 있는 아구형포자낭과 직경 $35\mu\textrm{m}$의 암색인 접합포자를 형성한다.

Filamentous fungi colonizing rice straw were collected from 11 different sites in Korea and were identified based on characterization of their morphology and molecular properties. The fungi were divided into 25 species belonging to 16 genera, including 14 ascomycetes, one zygomycete, and one basidiomycete. Fungal cellulolytic and xylanolytic enzymes were assessed through a two-step process, wherein highly active cellulase- and/or hemicellulase-producing fungi were selected in a first screening step followed by a second step to isolate the best enzyme-producer. Twenty-five fungal species were first screened for the production of total cellulase (TC), endo-${\beta}$-1,4 glucanase (EG), and endo-${\beta}$-1,4 xylanase (XYL) using solid-state fermentation with rice straw as substrate. From this screening, six species, namely, Aspergillus niger KUC5183, A. ochraceus KUC5204, A. versicolor KUC5201, Mucor circinelloides KUC6014, Trichoderma harzianum 1 KUC5182, and an unknown basidiomycete species, KUC8721, were selected. These six species were then incubated in liquid Mandels' media containing cellulose, glucose, rice straw, or xylan as the sole carbon source and the activities of six different enzymes were measured. Enzyme production was highly influenced by media conditions and in some cases significantly increased. Through this screening process, Trichoderma harzianum 1 KUC5182 was selected as the best enzyme producer. Rice straw and xylan were good carbon sources for the screening of cellulolytic and xylanolytic enzymes.
