The Flora of Higher Fungi in Mt. Jiri Areas (I)
Park, Seong-Sick ; Cho, Duck-Hyun ; Lee, Ji-Yul ;
The Korean Journal of Mycology, volume 14, issue 4, 1986, Pages 247~252
More than 300 specimens of higher fungi were collected in Mt. Jiri National Park areas from June, 1984 to September, 1985. These higher fungi were identified. As the resulting, Clitocybe flaccida (Fr.) Kummer, Tricoloma sejuctum (Fr.)
, Melanoleuca melaleuca (Fr.) Murr., Amanita rubrovolvata Imai, Rhodophyllus lazulinus (Fr.) ,
Paxillus involutus (Fr.) Fr., and Lactarius campholatus Fr. were new to be Korea.
Chromosomal Studies on the Genus Fusarium(I)
Min, Byung-Re ;
The Korean Journal of Mycology, volume 14, issue 4, 1986, Pages 253~256
Chromosome numbers were studied for three species of the genus Fusarium from observation of vegetative nuclear division in hyphae with aid of Giemsa-HCl techniques. It was confirmed that observation on the nuclear division could best be made at the growing hyphal tip and near the cells. The general shape of chromosome was dot-like form. The results confirmed that the chromsome number in n=8 in F. solani and F. moniliforme, and n=6 in F. cocophilum.

So as to clarify the biodegradation mechanism of lignin, lignin biodegradability among four white-rot fungi, Pleurotus ostreatus 1,2,3, and Polyporus versicolor were compared each other by simple plate test method, so that P. ostreatus 2 and P. versicolor exhibited the most wide clear zone. And to investigate the degree of lignin depolymerization, they were grown in ligninmedia where various carbohydrates were added, then that was analyzed through column chromatography. In consequence, P. ostreatus 2 and 3 showed more excellent effect of lignin depolymerization among those 4 white-rot fungi, and also in culture media in which glucose, cellobiose and xylose were added. When culture filtrates of the same media were scanned at UV range, there were no peak at 280 nm in the culture filtrate of P. ostreatus 2 and 3 where glucose, cellobiose and xylose were added. At the same time, culture filtrate, in which lignin was only contained as a carbon source, showed browning in color, whereas culture media with glucose, cellobiose and xylose in addition to lignin became yellowish (that is, decolorization). From above results, it might be assumed that polymerization and browning of lignin were decreased and lignin biodegradability was increased, when grown in lignin media where various carbohydrates were added.
Studies on Constituents of the Higher Fungi of Korea(LIV) -Studies on Toxic Component of Auricularia polytricha-

To screen biologically active components of the higher fungi of Korea, the dried carpophores of Auricularia polytricha were extracted with water. The extract was examined for acute toxicity in ICR mice. A low molecular weight toxin of this fungus was purified by a acetone precipitation followed by cellulose, silica gel and Sephadex LH-20 column chromatography. Major symptoms of this toxin were decreasing of normal motility, eye extrusion, hair erection, shivering, trembling of head, paralysis, rapid running or moving before death and depression of respiration. The median lethal doses of the total extract were 1. 28 g/kg and 4. 31 g/kg by i.p. and p.o. administrations, respectively. The amounts of one mouse lethal unit of the total extract and final fraction that killed a 20 g mouse within 30 minutes were 28.5 and 12.0 mg/mouse, respectively.
Characteristics of Protoplast Induction by Autolytic Enzyme of Rhizopus oryzae
Rhee, Young-Ha ; Choi, Yong-Keel ;
The Korean Journal of Mycology, volume 14, issue 4, 1986, Pages 273~280
The degree of autolysis and lytic enzyme production in the culture filtrate of Rhizopus oryzae was investigated. The formation of protoplast by using autolytic enzymes from Rh. oryzae was also attempted. Protoplasts were liberated from Rh. oryzae mycelium by lytic enzymes present in autolytic-phase culture filtrate. Maximum release of chitosanase and proteolytic enzyme into culture filtrate during autolysis was corresponded to maximum protoplast-liberating activity. High yields of protoplasts were obtained from 10 hr-age of Rh. oryzae mycelium with 0.5 M mannitol as osmotic stabilizer. The optimum temperature and pH for mycelium digestion were
respectively. The mycelium of the 18 hours cultures were treated with autolytic enzyme in same volume of osmotic stabilizer at
for 5 hours and then it was confirmed by scanning electoron microscope that protoplast were produced beside the digesting cell wall of the fungi.
