A Study of Antifungal Activity with Polygonum aviculare Linne
Kim, Hong-Sik ; Cho, Kwan-Hyun ;
The Korean Journal of Mycology, volume 8, issue 1, 1980, Pages 1~5
This study was undertaken to investigate the activity or the water extract of Polygonum aviculare Linne in vitro. Some of the purely isolated strains or dermatophytes were inoculated on Sabouraud's dextrose agar medium containing different concentrations of the Polygonum extracts and their growth was observed for about two weeks at room temperature. Then we measured the sizes of fungal colony grown in various conditions and compared them with those of Sabouraud's medium as control to determine fungistatic effectiveness of the extract. For additional study, slide cultures on Sabouraud's dextrose medium and Sabouraud's media containing 3ml/10ml extract were performed with Epidermophyton floccosum to observe the growth of hyphae, sporulation and other mycological findings. 1. The growth of Epidermo-phyton floccosum was completely inhibited in the media containing 3ml/l0ml Polygonum extract. 2. Trichophyton rubrum, Trichophyton mentagrophytes and microsporum canis were completely inhibited in several strains of each specimen and a moderate inhibitory effect was observed in all of another strains in the media containing the 3ml/10ml extract. 3. In the slide culture of Epidormophyton floccosum the hypha was thin and more desiccated. The characteristic macroco-nidia formation was not observed on the media containing 3ml/10ml Polygonum extract as compared with those findings of Sabouraud's dextrose control medium.

To increase production of Tricholoma matsutake, experiments were carried out in a mountain located in Keumma 2-ri, Joocheon-myun, Yongwol-gun, Kangwon-do, Korea during the period from April to November 1979. The area of the experiment showed pH 6.55 of soil acidity and the rock was found to be granite. Among its vegetation, the major growths were Pinus densiflora Siebold et Zuccarini, Rhododendron mucronulatum Turcz., Rhododendron schlippenhachii Max., Lespedeza bicolor and Pteridium aquilinum (Linne) Kuhn var. japonicum Nakai. Of two equally divided areas of A and B in which pine mushrooms grew, artificial methods such as thinning the upper portion of land raking and water-spraying were applied to area B only, where 21% increase of the production was obtained as compared with the control area A.

The Korean Journal of Mycology, volume 8, issue 1, 1980, Pages 13~19
To investigate constituents of Russula pseudodelica Lange and Microporus affinis(Blume et Nees) Kuntze, quantitative analyses of free and total amino acids were carried out with G. L.C. and an amino acid autoanalyzer. Polysaccharides of the two mushrooms were extracted with hot water and the filtrate was concentrated. The addition of three volumes of ethanol to the concentrate formed precipitation of crude polysaccharides which were analyzed by G.L.C. and H.P.L.C. Sixteen amino acids and four monosaccharides were identified in the protein-bound polysaccharides of the two mushrooms. The polysaccharides of M. affinis showed antineoplastic activity against sarcoma 180 implanted in mice.

To investigate constituents of Lentinus edodes grown on various, quantitative analyses of ash, crude protein, crude fiber, crude fat, water, nonsoluble nitrogen of the mushrooms were carried out by ordinary methods. The crude fat of the mushroom grown on chestnut tree(1.82%) was greater than that grown on oak (0.76%) or alder (1.17%) tree. The crude fiber of the mushroom grown on oak tree (12.50%) was greater than those grown on alder and chestnut trees, 9.85% and 8.52%, respectively. The crude protein, ash, nonsoluble nitrogen and water contents of the mushrooms grown on the three different trees were similar.

The Korean Journal of Mycology, volume 8, issue 1, 1980, Pages 33~43
Thirteen strains or crosses of Lentinus edodes obtained from home and abroad were compared for their mycelial characteristics on artificial media. Eleven of them were selected and inoculated on logs in order to study for their productivity, and the morphological characteristics of the mushrooms were investigated. 1) Seven strains, i. e., 11001, 12001, 13005, 13012, 13015, 12004 and 20101 were grown well on the sawdust medium. 2) The best mycelial growth and establishment of infection on logs were obtained from strains 20101 and 11001. 3) The highest yield of the mushrooms on logs during the six year periods were obtained from strains 11001, 12001 and 20101. 4) The highest yield of the mushrooms usually was obtained on the fourth year after inoculation. 5) The fruit body productivity in terms of dry weight recovery was the highest in strains 13005 and 20101. 6) The most productive period of the mushrooms during the years depended on strains. Most prevalent types of the strains were summer and autumn growing types, and more mushrooms were produced during these periods. 7) Morphological characteristics of the mushroom were more or less dependent on environmental conditions. 8) Thicker fruit bodies and relatively uniform shapes of the mushroom were produced by strain 20101.

This study was carried out from May, 1977 to July, 1979 in Phyllostachys reticulata forests located in both Yesan area (A) and Kwangsan area (B). The fungi isolated from these areas were purely cultured, identified and described. The results showed that 55 species of the fungi were recognized.
An Investigation of Undescribed Black Root Rot Disease of Soybean Caused by Cylindrocladium(Calonectria) crotalariae in Korea
Sung, Jae-Mo ;
The Korean Journal of Mycology, volume 8, issue 1, 1980, Pages 53~57
An undescribed black root rot of soybean, caused by Cylindrocladium crotalariae, was observed in Suweon area. The diseased plants showed yellowing at the top and dry rot at the root. Lesions of roots and stems in the soil were red to brown and main roots were cracked. Although not observed the disease in the field, leaves of inoculated test plants in the greenhouse exhibited circular, brown lesion surrounded by chloratic halos. The fungus was recovered in culture from the infected stem and root, and the perithecia of Calonectria crotalariae were demonstrated to be present as well as the cylindrocladium state. The fungus was pathogenic to the root, stem, petioles and leaves of soybean. The probable source of primary inoculum was microsclerotia formed in infected soybean root and stem from the previous season's soybean debris. Black root rot by this fungus was considered to be one of detrimental factors to the maximum yield of soybean. From the morphological and physiological characteristics and pathogenic behaviors, this fungus was identified as Cylindrocladium(Calonectria) crotalariae.

The Korean Journal of Mycology, volume 8, issue 1, 1980, Pages 59~62
Investigation on modification of aflatoxin structures by Pseudomonads was attempted as a biological detoxifiying process of mycotoxins. Firstly, when any variation of aflatoxin yield of Aspergillus parasiticus in a mixed culture with Pseudomonas aeruginosa was examined, there was no noticible effect by growth of Pseudomonads on aflatoxin yield of Asperillus sp. Secondly, when capacity of Pseudomonas aeruginosa utilizing aflatoxin as a carbon source for its growth was tested, there was some indication that aflatoxin might be used for growth of Pseudomonads. It was also noticed that the residual aflatoxin showed different migrating pattern compared with that of the intact aflatoxin by thin layer chromatography. Thirdly, the cell-free extract prepared from Pseudomonas aeruginosa grown in a glucose minimal medium supplemented with aflatoxin and the intact aflatoxins were incubated in the presence of
. After a certain length of incubation period, the reaction mixtures were applied on TLC plates. As a result, aflatoxins in the reaction mixture migrated differently as the control did. Such results may indicate that some changes of aflatoxin properties were induced by Pseudomonads.

was isolated from the culture filtrate of the penicillin producing strain, Penicillium chrysogenum Q176. When the pH of the medium was adjusted to 5.0 at the start of culture, a rapid increase in pH accompanied by the synthesis of penicillin was observed in the first
days. When the pH of medium was brought to 6.0 or 7.0 the opposite was observed: high yield of the enzyme and little of the antibiotics in the medium. The optimum enzyme activity was at a temperature of
and around pH 7.0. A partially purified enzyme was assayed on several different substrates including penicillins V and G, 6-aminopenicillanic acid, cephalosporin C. The V max values calculated were 24.5, 20.4, 7.6, and 6.1 mmoles/hour, and the
, values were 16.4, 12.6, 7.5, and 6.9 mM in the order given.

To establish a competent method of microbiological assay for bacampicillin, one of new semi-synthetic derivatives of
antibiotics, a comparison was carried out between different conditions for hydrolysis of bacampicillin into ampicillin which was then subjected to cylinder plate method. The results showed that the use of carboxylic ester hydrolase in vitro as a pretreatment of it in either pH value 6 or 8 was feasible and that the cylinder plate method with Sarcina lutea was adequate for potency estimation.
