양송이 합성배지(合成培地) 제조(製造) 및 균배양(菌培養)을 위한 Bulk Pasteurization System에 관한 연구(硏究)
신관철,Shin, Gwan Chull 충남대학교 농업과학연구소 1982 Korean Journal of Agricultural Science Vol.9 No.1
Bulk pasteurization system을 농가(農家)에 보급(普及), 실용(實用) 가능성(可能性)을 검토(檢討)하고 동(同) system을 이용(利用)한 퇴비배지(堆肥培地)의 발효방법(醱酵方法)을 확립(確立)하기 위(爲)한 실험(實驗)을 실시한 결과(結果)는 다음과 같다. 1. 양송이배지(培地)의 후발효과정(後醱酵過程)은 bulk pasteurization system으로 실시(實施)하는 것이 관행방법(慣行方法)보다 우수(優秀)하여 자실체수량(子實體收量)이 높았다. 2. Bulk pasteurization system으로 균배양(菌培養)을 한 결과(結果) 관행방법(慣行方法)보다 균사생장(菌絲生長)이 불량(不良)하고 수량(收量)이 낮았는데 이것은 송풍기(送風機)의 결함(缺陷)과 불완전(不完全)한 작업(作業)에 기인(基因)하였다. 3. 기존(旣存) 양송이재배사(栽培舍)를 개수(改修)한 간이(簡易) bulk pasteurization system은 배지(培地)의 발효(醱酵)가 불량(不良)하여 자실체수량(子實體收量)이 낮고 재배(栽培)의 안정성(安定性)이 적었다. 4. 배지(培地)의 후발효(後醱酵)를 bulk pasteurization 방법(方法)으로 할때 정열도달시간(頂熱到達時間), 후발효시간(後醱酵期間) 및 배지(培地)의 성분변화(成分變化)는 기온(氣溫)의 영향(影響)을 받았으나 관행방법(慣行方法)보다는 현저(顯著)한 안정성(安定性)을 보였다. 5. 시설(施設)이 잘된 bulk pasteurization system으로 후발효(後醱酵)할 때 입상시(入床時) 배지(培地)의 수분함량(水分含量)은 발효(醱酵)에 큰 影響을 미치지는 않았으나 배지(培地)의 성분(成分)에 약간 차이(差異)가 있었다. These studies were conducted to evaluate the bulk pasteurization system in comparison with the conventional mushroom growing technique of and to establish the phase II fermentation method for the system. The results obtained were as follows. 1. From the mushroom compost peak-heated in the bulk pasteurization system higher mushroom yield was obtained than that of the conventional method. 2. The compost fermented in the bulk pasteurization system showed poor mycelial growth and low crop. It was caused by the imperfect blower and its operation, not by ununiform moisture content of the compost and ununiform filling. 3. A bulk pasteurization system which modified the mushroom house was not proper for the fermentation of the mushroom compost and the sporophore yields were lower than the standard pasteurization system. 4. In the bulk pasteurization system, peak-heating time, phase II period and quality of the compost were influenced by the air temperature but its effects were not more significant than those of the conventional method. 5. During phase II in the bulk pasteurization system moisture content of the compost at filling did not affect the fermentation of the compost.

The fungal flora of Mt. Gyeryong National Park was investigated for the foundation of the nature studying garden and the nature conservation of the area during the period of July to October 1981. The fungi growing wildly in the area were collected and classified into 19 families, 53 genera, 93 species of Basidiomycetes and 5 families, 7 genera, 8 species of Ascomycetes. Species of Amanita, Boletus, Suillus, Russula, Lactarius, Laccaria and Marasmius were frequently observed during the hot and humid period. Well-developed communities of Lactarius piperatus, Russula emetics and Ramaria spp. were also found in Mt. Gyeryong. Unrecorded species of fungi in Mt. Gyeryong studied were not included in this report.

신관철,고승주 한국균학회 1985 韓國菌學會誌 Vol.14 No.1
The mating system of monokaryotic isolates in Pleurotus sajor-caju was controlled by two incompatibility factors A and B of tetrapola mating system. The mycelia of dikaryotic isolates grew faster than those of their component monokaryons, but no correlation between dikaryotic and their component monokaryotic isolates was found. The primodia formed well on the potato dextrose agar (PDA) media not only in the dikaryotic isolates but also in the monokaryons under irradiated conditions. The dikaryotic isolates produced normal sporophores; however, the monokaryotic isolates produced abnormal sporophores when they were cultivated with sawdust substrates. Some dikaryotic isolates derived by mating between monokaryotic isolates showed high yields of sporophores more than those of parental strains. Both the dikaryotic mycelial growth rate and primodia formation number on the PDA plate showed significant correlation with its sporophore products on sawdust substrates.

한국산(韓國産) 자생(自生) Ganoderma lucidum의 형태적(形態的) 특성(特性)
신관철,박용환,서건식,차동열,Shin, Gwan Chull,Park, Yong Hwan,Seo, Geon Sik,Cha, Dong Yeul 충남대학교 농업과학연구소 1986 Korean Journal of Agricultural Science Vol.13 No.1
A total number of 916 fruiting bodies of Ganoderma lucidum (Fr.) Karsten grown naturally in Korea were collected to investigate the morphological characters and some other useful characters related to the quality of the fungus and the results obtained are summarized as follows; The host tree showing the highest parasitic rate by the Genoderma lucidum(Fr.) Karsten was oak tree and the parasitic rate of the tree was 86.2%. The order of parasitic rate of the host trees by the fungus next to the oak was peach, chestnut, persimmon and acasia. The size, shape and color of fruiting bodies were varied according to the host trees. The average size of fruiting bodies collected was 40 to 100 mm by 30 to 80mm. The fruiting bodies with pileus size of 60 by 45 mm, pileus thickness of over 10mm, pileus minor axis/stipe length ratio of over 0.65 and pileus thickness/pileus minor axis ratio of over 0.22 were considered having higher commerical values. The external shape of the fruiting body was very important criterion to evaluate the quality of the Ganoderma lucidum (Fr.) Karsten. A great variation in characters such as pileus shape, color, marginal shape, zonation of pileus, pileus thickness, poroid layer of fruiting bodies and shape of stipe were observed from the fruiting bodies of G. lucidum collected in Korea. Further studies will be necessary for the genetic nature of these characters. Ganoderma lucidum (Fr.) Karsten (불로초(不老草), 영예)의 형태적(形態的) 특성(特性)을 구명(究明)하고 한국산(韓國産) 자생종(目生種)의 품질(品質)에 관계(關係)가 있는 형질(形質)을 조사(調査)하기 위하여 916점(點)의 영예를 수집(蒐集), 조사(調査)하였다. Ganoderma lucidum의 기생율(寄生率)은 참나무류가 전체의 86.2%였고 그 다음은 복사나무, 밤나무, 감나무, 아카시아나무 등(等)이었다. 기주(寄主)에 따라 자실체(字實體)의 크기, 형태, 색택에 차이가 있었다. 수집된 자실체(字實體)의 대부분(大部分)은 크기가 $40{\sim}100{\times}30{\sim}80mm$였고 자실체(字實體)의 갓의 크기는 $60{\times}45mm$ 이상(以上) 갓두께 10mm 이상(以上) 갓크기/대길이 율(率) 0.65 이상(以上) 갓두께/갓크기 율(率) 0.22 이상(以上)인 것이 상품가치가 높다. 영예자실체의 외형(外形)은 중요(重要)한 품질평가기준(品質評價基準)이다. 갓의 색택(色澤), 주연부의 모양, 갓의 윤문(輪紋), 갓의 두께 자실층형태(子實層形態), 대의 형태(形態)는 많은 변이(變異)를 보이고 있음이 관찰(觀察)되었다. 이 형질(形質)들이 유전성(遺傳性)인 것인지는 추후 구명(究明)되어야 한다.
