To find antitumor components with low toxicity from natural resources, antitumor test of the water extract of the carpophores of Trametes sanguinea (L. ex Fr.) Lloyd. was undertaken. The carpophores of this fungus were collected in Gyeong Gi Province and extracted with hot water. The extract was purified by dialyzing through Visking tube and a protein-bound polysaccharide fraction was obtained. The fraction was tested for antitumor activity against sarcoma 180 implanted in mice. The tumor inhibition ratio of the fraction against the tumor was 72.4% at the dose of 10mg/kg/day for the period of ten days. The tumor in one of the eight mice was completely regressed. The antitumor components were found to be a polysaccharide and a protein. The hydrolysis of the polysaccharide moiety yielded three monosaccharides, and from the hydrolysate of the protein moiety 13 amino acids were identified.

To find antitumor components, a protein-bound polysaccharide fraction was obtained by extracting with hot water and precipitating with ethanol from the carpophores and the cultured mycelia of Laccaria laccata. The fraction was examined for antitumor activity against sarcoma 180 implanted in mice. The component extracted from the carpophores showed 75% and 65% tumor inhibition ratios in the doses of 20 mg and 50 mg/kg/day, respectively. The protein bound polysaccharide fraction of the cultured mycelia of L. laccata also showed 57.8% tumor inhibition ratio in the dose of 20 mg/kg/day. The chemical analysis of the protein-bound polysaccharide fraction showed that it contained a polysaccharide and a protein. The hydrolysates of the polysaccharide moiety contained six and one unknown monosaccharides. Fourteen amino acids were identified in the hydrolysates of the protein moiety.

To investigate antitumor components of Korean higher fungi, the carpophores of Ramaria formosa
. were collected in Gang Won Province and extracted with hot water. The extract was concentrated and precipitated by four volumes of ethanol. The precipitate was centrifugated and purified by dialyzing through Visking tube and a protein-bound polysaccharide fraction was obtained. The fraction was tested for antitumor activity against sarcoma 180 implanted in mice. The tumor inhibition ratio of the fraction was 66% in the dose of 50mg/kg/day for the period of ten days. The tumor in two of the eight mice was completely regressed. The components of the fraction were found to be a polysaccharide and a protein. The chemical analysis of the fraction showed that the polysaccharide moiety consisted of four monosaccharides and that the protein moiety contained fourteen amino acids.

In cultivating the mushroom, there are important several mushroom diseases including Mildew disease, Didymocladium ternatum. Studies on some factors affecting growth of D. ternatum and its chemical control were carried out. The optimum temperature for mycelial growth of D. ternatum was
lower than that of Agaricus bisporus. Infection was very severe when it was infected between at casing and at the end of the first flush. Mycelial thermal death occurred at
when it was treated for more than 20 minutes. For spore,
for 60 minutes and
for 20 minutes were required respectively as a thermal death point. Benlate, Homai and Dithane M-45 were selected as effective chemicals for controlling this disease.

Gaeumannomyces graminis var. tritici was first isolated from rice in 1981. Sheath rot of rice seedling in box culture for machine transplanting was produced by artificial inoculation of the causal organism. Especially sheath rot was developed from crown to leaf sheath above water level. Perithecia were usually formed in dead leaf sheaths and in PDA culture. They were black, globose, and immersed with obliquely erumpent neck. Asci were unitunicate with an apical ring and contained 8 spores. Ascospores were hyline, slender,
in length. Each spore showed
Based on morphological and cultura characteristics, the isolate from seeds was identified as Gaeumannomyces graminis (Sacc.) Arx & Olivier tritici J. Walker.
Biochemical Characteristics of Apple Rot Caused by Macrophoma sp. (I) -Disease Development, Carbohydrate and Amino Acid Contents in Infected Fruits-
Hwang, Byung-Kook ; Lee, Yong-Se ;
The Korean Journal of Mycology, volume 10, issue 4, 1982, Pages 181~185
Immature apple fruits of cultivars Fuji and Miller were completely resistant to Macrophoma sp. until 10 July. When inoculated on 31 July, apples became susceptible to this fungus, irrespective of cultivar. This fungus grew better on Fuji than Miller. Lesion enlargement on apple at
was remarkably pronounced relative to
. In both cultivars, the amount of total soluble carbohydrates or reducing sugars in apple fruit flesh was gradually increased as apples became mature. The healthy apples of cultivar Fuji had a higher amount of carbohydrates than those of Miller. The infected apples contained more soluble carbohydrates in comparison to the healthy ones. In healthy apples, there were no consistent differences between Fuji and Miller in amount of total soluble amino acids. With increasing age of apples, the amount of soluble amino acids declined in the fruit flesh of both cultivars. Levels of carbohydrates and amino acids in apple fruits were discussed in association with the immature fruit resistance to Macrophoma sp.
Amino Acid Nutrition on Growth and Reproduction of Potato Dry Rot Fusarium roseum ‘Sambucinum' Variants
Lee, Chang-Un ;
The Korean Journal of Mycology, volume 10, issue 4, 1982, Pages 187~192
The effects of amino acids on mycerial growth and sporulation of the decreased and increased pathogenicity variants of potato dry rot Fusarium roseum ‘Sambucinum' were as following. The increased pathogenicity variants Ic52 and Ic116 showed the trend of greater mycerial growth, marking up to 67mg on leucine, than the decreased pathogenicity variants Dc14 and Dc91, and produced markedly low conidia below
or no sporulation. On methionine all the variants and the wild type showed the lowest growth recording 14mg to 20mg with no sporulation. Cystine similarly as glysine supported the poor growth 30mg to 19mg of the variants Dc14 and Dc91, respectively, and did not support the sporulation. The former amino acid like asparagine supported the growth of the variants Ic52 and Ic1l6 marking 47mg and 36mg, respectively. On all the eleven amino acids the variant Dc14 showed the trend of more mycerial growth and sporulation than the variant Dc91 which marked the exceptionally high sporulation
on glutamic acid.
Studies on Carbohydrate Accumulation in Aspergillus niger During the Differentiation
Kim, Shin-Sook ; Kim, Jong-Hyup ;
The Korean Journal of Mycology, volume 10, issue 4, 1982, Pages 193~202
The changes of total carbohydrates and trehalose levels during differentiation of A. niger were studied. Aspergillus niger was cultivated in Czapeck-Dox medium by the method of surface culture and shake culture. Total carbohydrates and trehalose were fractionated and determined by the method of Trevelyan and Harrison (1956). Total carbohydrates and trehalose accumulated in A. niger during sporulation. The influences of nutritional starvation on the levels of cellular carbohydrates in A. niger, which was cultivated in each nitrogen, phosphate and glucose limited Czapeck-Dox medium, were studied. The levels of total carbohydrates and trehalose in A. niger cultivated in nitrogen limited medium increased much than those cultured in full medium. The total carborates and trehalose levels in A. niger cultivated in phosphate limited medium increased, but the increases were less than those cultured in nitrogen limitted medium. In glucose limited medium, any changes of total carbohydrates and trehalose levels were not found. It is considered that the biochemical mechanisms responsible for the changes of total carbohydrates and trehalose levels may be related with differentiation of Aspergillus niger.

Studies on Antitumor Components of Flammulina velutipes of Korea(I) -Antitumor Activity against Sarcoma 180-
Woo, Myoung-Sik ;
The Korean Journal of Mycology, volume 10, issue 4, 1982, Pages 213~216
To find antitumor components with low toxicity in natural products of Korean Basidiomycete, the carpophores of Flammulina velutipes (Fr.) Sing. were extracted with hot water for eight hours. The extract was purified by dialyzing through Visking tube and a protein-bound polysaccharide fraction was obtained as pale brownish amorphous powder after it was freeze-dried. The fraction was examined for antitumor activity against sarcoma 180 implanted subcutaneously in the left groins of I.C.R. mice. The inhibition ratio of this fraction of against the tumor was 62.3% at the dose of 10 mg/kg/day for the period of ten days. The tumors in three of the ten treated mice were completely regressed.
