To isolate antibiotic-producing microorganisms from Korean soils, microbes were isolated from the soil samples and screened for antibacterial activity. A strain which was isolated from the soil sample collected in Choong Chung Book Do had a high antibacterial activity against gram-positive bacteria. The examination of morphological and physiological characteristics of that strain according to the International Streptomyces Project methods showed that it was one of Streptomyces species. After the antibacterial constituent of the strain was produced in submerged culture method, it was isolated and purified by XAD-2 and CM-Sephadex column chromatography. And it was found to be one of quinone type antibiotics.

The effects of cultural conditions on the mycelial growth and fruit-body formation and the yield of Pleurotus sajor-caju grown in rice straw medium were examined. The change of content of chemical components of mushroom and the medium during the cultivation period was also examined. The growth of mycelium was best in the medium sterilized for 60 min at
with a moisture content of 60%. The optimum pH and temperature for mycelial growth were 6.0 and
, respectively, whereas the optimum pH and temperature for fruit-body formation ranged from 5.0 to 6.0 and from 20 to
, respectively. Rice bran and starch cake were better than the other additives used for both mycelial growth and fruit-body formation. The optimum concentration of rice bran in the medium was 10%. The total yield of mushroom was
, 66% of which was prouduced from the first and second cropping period. As the harvest proceeded, the crude fiber cotent increased in the mushroom, whereas it decreased in the medium. The content of free sugar and crude ash, on the other hand, decreased in the mushroom, whereas it increased in the medium. The content of the other chemical components examined decreased in both the mushroom and the medium.
Effect of Water Potential on Mycelial Growth, Reproduction and Spore Germination by Fusarium moniliforme

Hyphal growth by Fusarium moniliforme was best at -14 bars osmotic water potential. Hyphal growth was prevented at -94 bars. The production of microconidia was best at -14 bars osmotic potential and prevented at -84 bars regardless of Strain. In contrast, this fungus sporulated macroconidia best at -1.4 bars and progressively less with each increment drop in water potential below that of basal media. The rate of spore germination followed a similar pattern with all of the spores; uniformly maximal at about -1.4 bars and progressively slower as the water potential was lowered from -1.4 bars to -42 bars. Under the natural conditions, plants infected by F. moniliforme produce microconidia on the dead tissues instead of producing macroconidia. This phenomenon agrees well with the water potential experiment since the dead plant tissues have a lower water potential than the living plant.

Seven seed samples of corn obtained from Kangweon Provincial Office of Rural Development, Kerea were tested for seed-borne fungi, and found that all the samples tested were infected with Fusarium moniliforme to an extent of
. Severely infected seed samples showed poor germination on blotter. Seed component plating showed that the fungus present not only in tip caps, pericarps and endosperms, but also in embryos. Heavy infection of the fungus caused severe seed rot and seedling blight in soil, but the damage was not severe and many plants grew without any symptoms when the seeds with light infection were sown in soil. However the fungus was frequently detected from inside of the stems of healthy looking seedlings. The results indicate that the fungus transmit from seed to plant systemically. In inoculation experiments, the fungus produced stem rots on corn plants of 110 days old. The cultivar of Hwangok 3 was revealed more susceptible to the fungus than that of Suweon 19.
Studies on Distribution of the Mononucleotides in Ganoderma lucidum

The Korean Journal of Mycology, volume 12, issue 3, 1984, Pages 111~116
Ribonucleic acid contents and mononucleotides distribution from the mycelium and fruit bodies of Ganoderma lucidum were studied. P.E.I. cellulose TLC and HPLC were applied in this study. The obtained results are as follows; The levels of ribonucleic acids from the young basidiocarp mycelium were higher than those of mature basidiocarp. Guanosine 5'-monophosphate and xanthosine 5'-monophosphate were found in both young basidiocarp mycelium and mature basidiocarp. The levels of guanosine 5'-monophosphate and xanthosine 5'-monophosphate from the young basidiocarp were higher than those of the mature basidiocarp. However, inosine 5'-monophosphate was not detected.
Studies on Constituents of the Higher Fungi of Korea(XLVIII) -Nematoxin of Naematoloma fasciculare-
Kim, Byong-Kak ; Shim, Mi-Ja ;
The Korean Journal of Mycology, volume 12, issue 3, 1984, Pages 117~119
To find toxic components in Korean higher fungi, the carpophores of Naematoloma fasciculare which had caused several cases of lethal intoxication were examined for toxicity. The components of high molecular weight were separated by ethanol precipitation and dialysis from the aqueous extract of the carpophores. After the components were freeze-dried, a brown powder was obtained. When a dose of 60mg/kg of this macromolecular fraction was intraperitoneally injected into mice, the mice began to die in six days and a half of them died within seven days. This toxic component was named nematoxin after the genus name of the mushroom.
