The changes of pH, titrable acidity, nitrite and dimethylamine(DAM) content in the various different kinds of the rice wine staters during the fermentation were studied, and the changes of nitrosodimethymaine(NDMA) contents were also determined by High Pressure Liquid Chromatography. After 24hrs, fermentation rice wine starter, pH was generally decreased to below 5 and after full fermentation the acidities were from 0.51 to 0.89 as succinic acid. After 12hrs, fermentation nitrate contents were rapidly decreased. The large amount of nitrite was formed in the beginning of the fermentation. But by the increase in the acidity due to the further fermentation nitrite contents were gradually disappeared. Generally the DMA contents of each rice wine starter were kept unchanged. On completion of fermentation, NDMA contents of starter added with nitrite and DMA were 472.1 ppb. The starter added with DMA was 329.0 ppb, whereas the other added with nitrite was 229.0 ppb, and control without addition of nitrite and DMA was 24.4 ppb. But the rice wine sold in market was not detected any NDMA at all.

Okhuoya, J.A. ; Ajerio, C. ;
The Korean Journal of Mycology, volume 16, issue 4, 1988, Pages 204~206
Chemical analysis of both sclerotia and the fruits of Pleurotus tuber-regium showed higher values for such elements as calcium(Ca), iron(Fe), zine(Zn) in the fruits than in the sclerotia. On the contrary magnessium(Mg) was found to be higher in sclerotia than in the fruits. protein and carbohydrate were also found to be more in the fruits. There was no significant difference between the chemical values of old(1 year) and fresh sclerotia. Oil palm fruit fibre substrate produced sporophores with higher values for the minerals, protein and carbohydrate than those on riversand substrate.
Sporocarp development of Pleurotus tuber-regium Fr. under different watering systems
Okhuoya, J.A. ; Ajerio, C. ;
The Korean Journal of Mycology, volume 16, issue 4, 1988, Pages 207~209
Sporocarps of Pleurotus tuber-regium Fr. were subjected to aerial and substrate(soil) watering sytems. Although aerial watering enhanced quick enlargment of pilei, those watered indirectly through the soil developed more naturally pigmented sporophores and with higher overall yield. Thus, substrate(soil) watering after emergence is preferred to direct watering of fruits.

Several reversion colonies were obtained after induced transfer of the isolated nuclei from P. sapidus into protoplast of P. ostreatus
. These colonies showed three distinct cultural characteristics, type 1 produced spontaneous segregants of both parental types, type 2 showed segregants of non parental types, and type 3 gave rise to homogeneous colonies. Isozyme patterns of esterase, malate dehydrogenase and superoxide dismutase showed substantial differences between parents and nuclei transferred strains. This observation supported that the isolated nuclei of P. sapidus were transferred into protoplast of P. ostreatus and expressed in recipient cell.

The Korean Journal of Mycology, volume 16, issue 4, 1988, Pages 214~219
Factors affecting protoplast formation and reversion were investigated in Pleurotus sapidus kalchbr. For release of protoplast, enzyme mixture of Novozyme 234,
was most effective, when mycelium of 0.6 M sucrose solution as osmotic stabilizer without addition of buffer solution. The yield of protoplast was highest with mycelium cultured for 4 days on mushroom complete agar medium at
. Protoplasts of Pleurotus sapidus were reverted to normal hyphal growth with maximum reversion frequency of 2% on Mushroom complete agar medium stabilized with 0.6 M sucrose solution and covered by 0.75% agar layer.

This study was carried out to investigate the effect on the system of crop rotation of sesame(Sesamum indicum L). The results of infected plant percentage and yield of sesame wilting disease, fluctuation of density of Fusarium oxysporum and Actinomycetes, and their pathogenicity test on Fusarium spp isolated from sesame cultural soil were investigated. Density of F. oxysporum was the highest in a sesame continuous cropping soil but that of Actinomycetes was the lowest in that soil. And that of F. oxysporum and Actinomycetes according to investigation date was the highest at June. 30 and July. 30, respectively. Their pathogenicity of F. oxysporum and F. solani isolated from sesame cultural soil to sesame, peanut and green gram were recognized to all isolates except one isolate among F. oxysporum 8 isolates and one isolate to sesame, 2 isolates to peanut and all isolates to green gram among F. solani 4 isolates. F. oxysporum density and infected plant of wilting disease were increased as a result of replanted cultivation of sesame, and yield of that was prominantly reduced. Relation between density of F. oxysporum in cultural soil and infected plant percentage showed positive correlation and yield index highly negative. There was little difference between sesame-upland rice and sesame-peanut in the system of crop rotation.

More than one-hundred-twenty specimens of Basidiomycetes, Ascomycetes and slime molds were collected in Seoul National Polytechnic University Campus during the priod from June 1984 to November 1987 and examined for identity. They were classified into 25 families, 53 genera and 81 species. Among them, one genus and 2 species were confirmed as unrecorded taxa in Korea. The unrecorded genus was genus Hapalopilus and was named 'Band Dal Busut' in vernacular. The unrecorded 2 species were Hapalopilus rutilans and Hygrophorus nitratus. They were named 'No Lan Ban Dal Busut' and 'Jil San Beot Geot Busut,' respectively and their characteristics were here reported.

Ganoderma lucidum, a divine mushroom, beared the nonbasidiocarpus basidiospore without the normal basidiocarp. The fungus formed the basidial stroma from the aerial mycelium on agar media, and the basidium was developed from apical cells of the mycelium on the surface of the basidial stroma. One to four basidiospores were observed on a basidium. The nonbasidiocarpous basidiospores formed on the basidial stroma were similar to the normal basidiospores in morphology, although the nonbasidiocarpus basidiospores were slightly smaller in size. However, the number of hollow on the spore surface was remarkably smaller than that of the normal spore. The formation of nonbasidiocarpous basidiosproes was influenced by the genetic factor and the environmental factors such as light, temperature and ventilation.

This study was carried out to investigate some morphological characters of fruit bodies of Ganoderma lucidum and to classify the fungus on the bases of the genetic character. Some of the isolates of the fungus which originally have the kidney-shaped fruit bodies produced the antler-shaped fruit bodies on artificial media and the latter characters were inherited. Pattern of the pileus surface and thickness of the pileus of the fruit bodies were also considered to be hereditary. Although morphology of the pileus margin and fruiting mode of the fungus were variable among the isolates, they were greatly influenced by environment conditions. Ganoderma lucidum could be classified into two groups and four strains according to the morphology of the fruit bodies on artificial cultivation media. Electrophoretic patterns of esterase, peroxidase, leucine aminopeptidase(LAP) and proteins of fruit bodies and mycelia of Ganoderma lucidum showed high genetic variation. Isozyme patterns of esterase of the mushroom mycelia were applicable for the classification of strains of the fungus. Patterns of proteins, leucine aminopeptidase and peroxidase did not indicate any genetic relation among the fungus strains.
Studies on Inorganic Components of Korean Mushrooms(I) - Inorganic Components of Laccaria laccata, Laccaria amethystina, Laccaria tortilis and Laccaria vinaceoavellanea -
Park, Wan-Hee ;
The Korean Journal of Mycology, volume 16, issue 4, 1988, Pages 242~246
To determine contents of inorganic elements of Laccaria, the carpophores of Laccaria laccata(Fr.) Berk. et Br., Laccaria amethystina(Fr.) Berk. et Br., Laccaria tortilis(S.P. Gray) Cooke and Laccaria vinaceoavellanea Hongo were incinerated and analyzed by atomic absorption spectrophotometer. Total contents of determined inorganic elements(except Cd) were highst in Laccaria tortilis than the other three mushrooms, and Laccaria vinaceoavellanea, Laccaria laccata and Laccaria amethystina in that order. The four species mushrooms contained potassium, iron, zinc, sodium, copper, manganese, and calsium in that order, and the content of potassium was the highst than the other inorganic components. The content of cadmium was Laccaria tortilis, Laccaria laccata, Laccaria vinaceoavellanea and Laccaria amethystina in that order.

The uptake of isolated Lyophyllum ulmarium chromosomes by Ganoderma applanatum protoplasts was induced with polyethylen
. Uptake products of chromosomes by protoplasts showed micro-and macrotransgenome type. The former was slowly growing and unstable, the latter was outgrowing and stable mycelial colonies which made thick hyphae of width and segregation of mycelial colony on GCM containing benomyl. A comparison of macrotransgenome type was using isozyme analysis of esterase. The enzyme pattern of two transformants was distinct in position and quantity compared with parents.
