Several higher fungi were collected at Andong during the. summer and fall of 1976. About 100 higher fungi were collected at Mt. Sobaek and Youngju during the same period in 1978. These higher fungi were identified. As the results, Macracystidia proved to be new genus in Korea. And the following are also newly-found species. in Korea. Hygrocybe turunda (Fr.) Karst., Hygrophorus lucorum Kalchbr.. Macrocystidia cucumis (Fr.) Heim var. latifolia (Lange) Imzzeki et Hongo, Agaricus subrufescens Peck, Psathyrella hydrophila (Bull. ex Fr.) A.H. Smith, Stropharia rugosannulata. Farlow f. lutea Hongo, Inocybe bresadolae Mass., Inocybe. multicoranata A.H. Smith, Russula farinihes Romell and Lactarius sakamotoi Imai.
한국산 고등 균류의 성분 연구 (9) : 양송이 버섯의 지방산 성분 Fatty Acids from Agaricus bisporus
김병각,심미자,이만동 한국균학회 1978 韓國菌學會誌 Vol.6 No.1
Attempts were made to investigate on the fatty acids of Agaricus bisporus a cultivated edible mushroom. Fats were extracted from 'it and saponified with alcoholic potassium hydroxide. Isolated fatty acids were methylated and were subjected to column chromatography and G.L.C. Eleven saturated fatty acids, i.e., dodecanoic, tridecanoic, tetradecanoic, pentadecanoic, hexadecanoic, heptadecanoic, octadecanoic, eicosenoic, uncosenoic, docosenoic, and tricosenoic acids, were identified. Especially palmitic and stearic acids were abundant. Nine unsaturated fatty acids appear to exist in the carpophore.

Of 450 Strains isolated from the soil microbes collected in various locations in Korea, a strain had a strong inhibitory activity against bacterial α-amylase and was named strain DMC-72 of the genus Streptomyces. The amylase-inhibitory metabolite produced by this strain was purified by means of acetone precipitation, adsorption on Amberlite IRC-50 and XAD-8, and column chromatography on Amberlite CG-50 and SP-sephadex C-25. The inhibitor which was stable at the pH range of 1∼13 and at 100℃ for half an hour also inhibited other amylases such as salivary α-amylase, pancreatic α-amylase, fungal α-amylase and glucoamylase, but it showed no inhibitory activity against α-glucosidase, β-glucosidase, dextranase and β-amylase. The kinetic studies of the inhibitor showed that its inhibitory effects on starch hydrolysis by α-amylase were non-competitive.

To find antimicrobial strains of the soil microorganisms in Korea, they were isolated from the soil samples of different locations and screened for antiobiotic activity against several standard microbes. An isolate among them had an antibacterial activity against grampositive bacteria. The examination of its morphological and biochemical characteristics according to the International Streptnmyces Project methods showed that it belongs to the genus Streptomyces. The strain appears to be a new strain when it was compared with the species within the genus which have been so far reported. The antibiotic metabolite was produced in submerged culture method. Attempts were made to characterize the chemical properties of the antibiotic metabolite.

To investigate constituents of Lampteromyces japonicus (Kawam.) Singer which grows wildly in Korea, the carpophores of the fungus were collected in Gyeong Gi Province and analyzed for sterols and amino acids by gas chromatography and an amino acid autoanalyzer. The results showed that it contained stigmasterol and ergosterol and that it contained eleven free amino acids. These free amino acids were also determined quantitatively. Furthermore, sixteen amino acids were identified in the total amino acid fraction of the fruiting body.

저자들은 Amanitaceae에 속하는 버섯의 일종인 Amanita spissacea와 Amanita vaginata의 형태학적 특징 및 이들 버섯중에 함유되어 있는 아미노산 분석을 시행하였다. gas chromatography를 이용하여 14종의 유리 아미노산을 확인하였고 8종의 유리 필수 아미노산을 정량하였다. 그리고 이미노산 자동분석기를 이용하여 이들 버섯의 산 가수분해물에 대해 총 아미노산 분석을 시행하였다. 그 결과 Amanita spissacea와 Amanita vaginata에서 14종의 유리 아미노산을 확인하였고 또한 8종의 유리 필수 아미노산중 둘 다 threonine이 가장 많아서 각각 7.3mg/g, 3.2mg/g이었고 총 아미노산 분석 결과 16종의 아마노산을 확인하였고 총 함량은 각각 138mg/g 및 166mg/g이었다. Amanita spissacea which is indiginous to Korea and Japan and Amanita vaginata which is an edible mushroom, grow wildly in Korea. However, their constituents have never been studied. These higher fungi were collected in the Gyeong Gi Province, Korea, and analyzed for their free and total amino acids, using gas chromatography and amino acid auto-analyzer. Fourteen free amino acids (alanine, glycine, valine, leucine, isoleucine, threonine, aspartic acid, methionine, phenylalanine, histidine, tyrosine, lysine, arginine, and tryptophan) were identified in both species. The contents of eight free essential amino acids in A. spissacea and a. vaginata were : threonine 7.26 and 3.15 mg/g, lysine 2.85 and 2.5 mg /g, methionine 2.48 and 2.70 mg/g, phenylalanine 1.35 and 0.98 mg/g, isoleucine and leucine combined 1.65 and 1.05 mg/g, valine 1.24 and 0.68 mg/g, and tryptophan 0.90 and 0.93 mg/g, respectively. The total contents of the respective amino acids in A. spissacea and A. vaginata were: lysine 5.18 and 12.28 rngj'g, histidine 3.00 and 5.12 mg/g, arginine 7.76 and 9.80mg/g, threonine 8.88 and 8.00 mg/g, glutamic acid 20.10 and 34.94 mg/g, alanine 10.22 and 11.62 mg/g, valine 9.64 and 8.94 mg /g, glycine 8.32 and 8.30 mg/g, methionine 1.90 and 1.63 mg/g, isoleucine 6.66 and 7.88 mg/g, leucine 12.74 and 14.00 mg/g, phenylalanine 7.00 and 7.82 mg/g, cysteine 0.82 and 1.26 mg/g, aspartic acid 16.94 and 15.28 mg/g, serine 9.84 and 10.34 mg/g and threonine 3.62 and 3.90 mg/g, respectively.
