Cho, Duck-Hyun ; Park, Seong-Sick ;
The Korean Journal of Mycology, volume 19, issue 4, 1991, Pages 241~249
Eight species of genus Entoloma were collected from the areas of Mt. Naejang National Park, Mt. Jangan Provincial Park and Mt. Manduck and newly identified in Korea: Entoloma squamodiscum, E. nigroviolacem var. nigroviolacem, E. subrhombisporum, E. spadix, E. fumosialbum, E. peckianum, E. strictius var. strictius and E. albatum.

Four species of the Myxomycetes (Order Liceales) collected from Bendel State, Nigeria, and newly described; Licea kleistobolus, L. pusilla, Cribraria lepida and Dictydium cancellatum. All of them are new records for Nigeria.
Analyses of cellular carbohydrates in Leucosporidium scottii and its related texa of basidiomycetous yeasts by the high performance liquid chromatography
Joo, Woo-Hong ;
The Korean Journal of Mycology, volume 19, issue 4, 1991, Pages 253~257
Cellular carbohydrates were hydrolysed and analyzed in the strains of Leucosporidium scottii and its related species of basidiomycetous yeasts by HPLC methods without any derivatization. Xylose was detected from the hydrolyses of the cellular carbohydrates of L. lari-marini, but not from those of three strains of L. antarcticum, L. fellii, and Rhodosporidium fluviales. not also from those of six strains of L. scottii contrary to other data reported. L. antarcticum and L. lari-marini were considered to be placed on the different genus of Cystofilobasidium or Mrakia, as based on the numerical analyses.
Ubiquinone compounds of the strains in Leucosporidium scottii and its related taxa
Joo, Woo-Hong ;
The Korean Journal of Mycology, volume 19, issue 4, 1991, Pages 258~265
Ubiquinone compounds of strains in Leucosporidium scottii, Leucosporidium fellii, Leucosporidium lari-marini, and Rhodosporidium fluviale were analyzed by the high performance liquid chromatography. The Q-9 or Q-l0 compounds, independent on mating or self-sporulating type, were determined in the analyses of Leucosporidium scottii strains. Particularly, there is heterogenous in the quinone compounds in the same strain of L. scottii. These results showed reassessment of the quinone compounds as a taxonomic criterion; L. fellii had the Q-9 compound, L. lari-marini the Q-8 compound, and R. fluviale the Q-10 compound, Taxonomic position of L. lari-marini should be elucidated on the basis of analysis of Q-compound with other aspects.

The gene CDC70 encoding the
of G protein has been known to be a component involved in mating pheromone signalling in the yeast, Saccharomyces cerevisiae. To isolate mutations of the genes involved in the signal transduction, Saccharomyces cerevisiae the strain bearing the cdc70-5 mutation was mutagenized to be forced to recover the ability of colony-formation at restrictive temperature, which means the new mutation can suppress the temperature sensitivity of the cdc70-5 phenotypes. Among these suppressors,
mutations are excluded because of no relationship to signal transducer. And the selected suppressors were analyzed for the linkage relationships by the tetrad analysis. Out of fifteen suppressors isolated, twelve were classified into four linkage groups, designated as sga1, sga2, sga3, sga4 by the tetrad analysis. The other three genes were determined for the linkage.
Comparative studies on xylose utilization and fermentation by Pachysolen tannophilus fusants and auxotrophs

The Korean Journal of Mycology, volume 19, issue 4, 1991, Pages 276~281
Auxotrophs induced by UV irradiation were Iysine, arginine, methionine, and cysteine requirement. The optimal protoplast-producing conditions of Pachysolen tannophilus were obtained in 1 hr incubation treated zymolyase 0.5 mg/ml at
(pH 6.5-8.5 with 0.6 M KCI as osmotic stabilizer. Cell volumn of fusants were counted in about 4 times of parents and their morphological characteristics were similar to parents which were global or egg-shaped, though in fusant, pseudohypha were observed frequently. Ethanol production of fusants were similar to parents, but arginine and methionine auxotrophs were showed increased ethanol production respectively 1.6 times and 1.25 times more than parents.
Preventive Effect of Lysis in the Cadmium-Tolerant Hansenula anomala B-7 Cells by Metal Ions
Song, Hyung-Ik ; Yu, Tae-Shick ;
The Korean Journal of Mycology, volume 19, issue 4, 1991, Pages 282~284
The yeast, Hansenula anomala B-7, isolated from the
rich soils and determined to be tolerant in the high concentration of
were employed in this work. Its intact cells grown in high concentration of
were observed to be Iysed at the early stage when transferred to a cadmium deficient broth. Its intact cells found to be not Iysed and grow well under the high concentration of
. The Iysis of the intact cells grown at the high concentration of
ion was not found when the metal ions were replaced with
ion in the same concentration. This result indicated that Iysis of yeast cells, at least in this isolate, would be related to cell osmosis with the mineral ions added.
Effect of Sulfur Dioxide on Oyster Mushroom in Yeochun Industrial Complex Area
Shin, Kwan-Chull ; Oh, Man-Jin ;
The Korean Journal of Mycology, volume 19, issue 4, 1991, Pages 285~291
Sulfur dioxide discharged from the factories in Yeochun industrial complex severely damaged to the growth of oyster mushrooms. The continuous monitoring indicated that high concentration of sulfur dioxide was repeatedly detected in Kwang-Yang and Seung-Ju. The first injury symptoms on the mushroom fruit bodies were observed a day later when sulfur dioxide was detected over 300 ppb. Under the high concentration of sulfur dioxide exposure, the young fruit bodies showed blight and sudden death and the mature fruit bodies turned to blue-brown and frequently progressed to blight. The symptoms at Spring cropping were more severe than those at Autumn cropping. The severity was associated with the frequency of sulfur dioxide monitored. However, sulfur content in the mushroom fruit bodies and culture media did not show clear differences between the injured mushroom from Yeochun industrial complex areas and normal ones from no damaged areas.
Changes of Volatile Components of Pleurotus sajor-caju During Storage
Jung, Soon-Taek ; Hong, Jai-Sik ;
The Korean Journal of Mycology, volume 19, issue 4, 1991, Pages 292~298
Volatile aroma concentrates of Pleurotus sajor-caju which stored at
incubator and cold room were obtained by simultaneous distillation-extraction method. The volatile components were identified by combined capillary gas chromatography-mass spectrometry and comparison of retention data on GC of those authentic compounds. Storage at room temperature resulted in significant decreased in their total aroma contents, whereas little changes at cold storage foured, even though appreciable changes were observed in GC pattern between the control and stored samples. Of 38 components identified,
increased while rest of the volatiles decreased rapidly during storage at room temperature, but at cold storage 2-methyl butanal, 1-octen-3-ol, cis,cis-1,5-octadien-3-ol and pentadecanoic acid decreased while 3-octanone, 1-octen-3-one, 3-octanol and 5-undecanol increased with the storage time. The weight losses and organoleptic properties changed extremely by the storage under room temperature, on the other hand, slight changes were found in cold storage.

The Korean Journal of Mycology, volume 19, issue 4, 1991, Pages 299~305
Volatile aroma concentrates of four oyster mushrooms cultivated in Korea were obtained by the simultaneous distillation-extraction method. The volatile components were identified by the combined capillary gas chromatography-mass spectrometry and compared with the of retention data on GC of those authentic compounds. About 54 volatile compounds were identified in each of the four edible oyster mushrooms. The main compounds in Pleurotus ostreatus ASI 201 were 1-octen-3-ol, 3-octanone, 3-octanol, in Pleurotus sajor-caju, 1-octen-3-ol, 3-octanone, 1,5-octadien-3-one, 3-octanol, in Pleurotus florida-ostreatus-ostreatus, 1-octen-3-ol, n-hexanol, 3-octanone, 3-octanol, phenol, and in Pleurotus ostreatus (Ae-Neutari), 1-octen-3-ol, n-pentanal, n-hexanol, n-pentanol, 3-octanone, 3-octanol, 1,5-octadien-3-one, respectively. The mushrooms worked were rich in an alcohols and carbonyl compounds containing
compounds. The peak area ratio of
compounds in aroma concentrates were 56.60% in Pleurotus ostreatus ASI 201, 72.46% in Pleurotus sajor-caju, 54.84% in Pleurotus florida-ostreatus-ostreatus and 35.85% in Pleurotus ostreatus (Ae-Neutari ), respectively.
