Ecological Study on Arbuscular Mycorrhizal Fungi in the Soils around Leguminous Plants in Korea
Ahn, Tae-Kun ; Lee, Min-Woog ; Lee, Sang-Sun ;
The Korean Journal of Mycology, volume 20, issue 3, 1992, Pages 204~215
From 12 August to 21 November in 1991, 65 soil specimens were collected from nineteen leguminous plant roots throughout nine locations of four provinces. They were sieved to collect and identify the arbuscular mycorrhizal spores (four genera, 21 species). The species of Glomus were most commonly (47.6% of all observations) found, but the species of Gigaspora (about 4.8% of all observations) occurred infrequently or rarely rather than the species of the other genera. The most common arbuscular mycorrhizal species at nine locations were Acaulospora laevis and Glomus laminated spores cf. macrocarpus var. macrocarpus. All of nineteen legume plant species collected were found to be associated with the arbuscular mycorrhizal fungi . Cassia mimosoides var. nomame and Kummerowia striata in legume plants had the great frequency of arbuscular mycorrhizal fungi associated with their roots. The number of isolated spores were ranged from 0.3 to 10.0 spores per 10g of soil. The species diversity of arbuscular mycorrhizal spores at the disturbed areas were calculated to be bigger than those in the natural vegetation areas.

Byun, Myung-Ok ; Cha, Dong-Yeul ;
The Korean Journal of Mycology, volume 20, issue 3, 1992, Pages 216~221
Aerial crystalline filaments emerged from dense type of mycelia on some monokaryotic transformants of Pleurotus florida, P. ostreatus and P. sajorcaju. Cytstals were not dissolved in water but soluble in ethanol or at the temperature of higher than
. Crystals were detected in the mycelia grown on the mushroom minimal medium as well as the mushroom complete medium. They were produced on both liquid media and agar plate. Although the mycelia incubated at
, produced crystals, the mycelia incubated at
did not. Furthermore, crystal forming mycelia were obtained from monokaryotic basidiospore of P. ostreatus and P. sajor-caju by mutations (UV irradiation).

Byun, Myung-Ok ; Kim, Kyung-Soo ; Cha, Dong-Yeol ;
The Korean Journal of Mycology, volume 20, issue 3, 1992, Pages 222~228
Pleurotus florida was transformed by complementation of auxotrophic mutant using chimeric plasmid containing Flammulina velutipes leu 2 gene and pBR 322 replicon. Mycelial morphology of transformants was grown and compared on mushroom complete and minimal medium. Transformants were mated with monokaryon and their genetic recombination was investigated for the morphology of fruitbody and spore analysis.
transformant showed same mating type of
as to the untransformed mutant. The transformant and the untransformed mutant were mated with monokaryon of which mating type is
, respectively. Although fruitbody of the untransformed mutant was not produced,
transformant produced fruitbody. Spore analysis showed that leucine requiring spores from fruitbody of
transformant were diminished when compared with those of untransformed mutant.

Go, Seung-Joo ; Cha, Dong-Yuel ; Wessels, J.G.H. ;
The Korean Journal of Mycology, volume 20, issue 3, 1992, Pages 229~233
Although there were differences depending on strains and environmental conditions, virus infected oyster mushroom, Pleurotus florida showed slow growth on sawdust and rice straw substrates. Many harmful microorganisms occurred on the cultural bed of virus infected isolates. Pinhead formed too densely or too rarely sometimes. Stipes of the mushrooms were long slightly bent with small cap. The virus infected mushrooms formed branch on their stipes. The first pinheading days of the infeeted mushroom were later than that of healthy culture. The loss of fruit body yield was about 30% compared with that of virus free culture. Spores which contaminated by viruses damaged more seriously than the other source. The authors would like to call these symptoms as a new disease in oyster mushroom culture in the world.
Molecular Analysis of double-stranded RNA in Abnormal Growing Oyster-Mushrooms, Pleurotos florida and P. ostreatus due to Virus Infection
Go, Seung-Joo ; Park, Yong-Hwan ; Shin, Gwan-Chull ; Wessels, Josep G.H. ;
The Korean Journal of Mycology, volume 20, issue 3, 1992, Pages 234~239
The experiment was performed to find out the possibilities to detect virus infection in oyster mushrooms, Pleurotus species by analysis of doublestranded ribonucleic acid (ds RNA). Ds RNA segments were extracted from virus infected isolates which grew abnormally. But virus free isolates didn't show any ds RNA segments. The ds RNA was consisted of one large segment of 8100 base pairs (bp) and 4 smaller segments with 2170, 2120, 1980 and 1984 bp. Whereas, cell free virus particles showed only one larger ds RNA segment. The ds RNA was dissolved by RNase A in low salt, 0.1 M SSC and melted at
. It was possible to use the ds RNA analysis for detecting virus infection directly from the host cells.

The Korean Journal of Mycology, volume 20, issue 3, 1992, Pages 240~251
To find antitumor components from higher fungi, the cultured mycelia of Paxillus atrotomentosus were extracted with hot water. The water soluble fraction was purified and separated by DEAE-cellulose ion exchange chromatography and Sepharose CL-4B gel filtration method. The separated fractions(Fr.) were designated CR A, B, C and D. Fr. A showed the highest inhibition ratio of 68.51% among the five tractions at a dose of 20 mg/kg/day. When Fr. A was examined for immunopotentiation activity, it increased the amount of the superoxide anion from activated macrophages to 1.1 fold and the number of plaques in hemolytic plaque assay to 2.3 fold, respectively. Otherwise, it did not show direct cytotoxity in sarcoma 180. Delayed type hypersensitiyity reaction showed that the decreased footpad swelling of tumor-hearing was restored to the normal. These results indicate that antitumor activity was exerted through immunopotentiation. Its chemical analysis showed 86.36% polysaccharide, 1.52% protein and 1.64% hexosamine. The polysaccharide consisted of fucose, galactose, glucose, mannose and xylose. This component was named paxillan.

Zohri, A.A. ; Khayria, M. ; Gawad, Abd. El. ;
The Korean Journal of Mycology, volume 20, issue 3, 1992, Pages 252~258
Thirty three species and two species varieties belonging to 14 genera of fungi were collected from 20 cowpea cultivars on glucose Czapek's agar (11 genera and 25 species+1 var.) and glucose-Czapek's agar supplemented with 10% NaCl (7 genera and 18 species+2 var.) at
. The total count of fungi were 6716 colonies/g in all cowpea cultivars. On glucose-Czapek's agar and identified; Aspergillus flavus, A. niger, A. sydowii, A. flavus var. columnaris, A. terreus, Penicillium chrysogenum, Emericella nidutans and Rhizopus stolonifer. The total count of halotolerant or halophilic fungi was 3515 colonies/g on 10% NaCl-glueose-Czapek's agar and identified; the most common species were: A. flavus, A. sydowii, A. tamarii A. flavipes, A. niger, A. flavus var. columnaris, A. ochraceus, A. oryzae and P. chrvsogenusm. Thin layer chrormatographic analysis of chloroform extracts of the different seed samples revealed that four cultivars were naturally contaminated with aflatoxins
Isolation of Antibiotic-Producing Actinomycetes Antagonistic to Phytophthora capsici from Pepper-Growing Soils
Ahn, Sang-Joon ; Hwang, Byung-Kook ;
The Korean Journal of Mycology, volume 20, issue 3, 1992, Pages 259~268
Fifty-three actinomycetes antagonistic to Phytophthora capsici and Magnaporthe grisea were isolated from rhizosphere soils in six pepper-growing areas and ashore soils. Thirty-two antagonistic actinomycetes, showing inhibition zone larger than 5 mm, were classified into 20 groups according to their colony morphology and color. The antagonistic activity against P. capsici greatly varied, which showed inhibition zone sizes in the ranges from 5.7 to 17.5 mm on V-8 juice agar and from 2.5 to 17 mm on tryptic soy agar. The antagonistic activity of some actinomycetes tested was remarkably different between the two test media. The antagonists showed a relatively broad antifungal spectrum, but their antibacterial activity was negligible, except for Pseudomonas solanacearum. Butanol extracts of culture filtrates from antagonistic actinomycetes inhibited mycelial growth of P. capsici and M. grisea, thereby confirming strongly antibiotic production in culture. Culture filtrates of some antagonistic actinomycetes completely inhibited Phytophthora blight in pepper plants.
A Survey of Yeasts Found in the Air of El-Minia City, Egypt
Haridy, Mamdouh S.A. ;
The Korean Journal of Mycology, volume 20, issue 3, 1992, Pages 269~272
208 yeast strains were isolated from air at El-Minia city, Egypt. Using 22 morphologi cal and physiological merkmals, these strains were identified and assignned to eight species belonging to seven genera. Rhodotorula mucilaginosa and Cryptococcus albidus were the most dominant species followed by Debaryomyces hansenii. These yeast species occurred regularly, whereas other species appeared sporadically. Rh. rubra, Saccharomyces kluyveri and Rh. aurantiaca were also isolated from the sampled air. The results of this study showed that time, hight and area of air sampling affect composition and total counts of yeast microflora in the air.

Armillaria mellea mushrooms were cultivated on the sawdust media, Quercus sawdust; rice bran=80:20 in polypropylene bags. The isolate of Armillaria mellea used was ARM69002F collected from a Korean pine plantation in Hongcheon district. The length of time between spawning and fruiting was required for 90 to 100 days. The number of fruiting bodies produced in a bags with a kg substrate were approxinately 31 (range of 18 to 62), and the total fresh weight 158g (61 to 207g), converted to 13 to 15% of fresh weight. The pilei of fruiting bodies were average 4.0 cm (2.5 to 7.6 cm)wide, and their stipes 8.2 cm long and 0.6 cm-thick at the upper part and 1.2 cm at the base.
