  • 땅콩을 대상으로 하는 각종 농산가공기계의 개발 및 최적 작동에 필요한 땅콩 자실의 물리적, 기계적 및 공기 역학적 성질에 대한 연구가 수행되었다. 영호, 올, P.I. 314817의 3 가지 품종에 대해 땅콩 자실의 형상, 각부 칫수, 진밀도, 산물밀도 및 종실율이 측정되었으며, 땅콩자실에 대해 압축실험을 실시함으로써 자실이 파괴될 때의 힘, 변형량, 그리고 단위 체적당 최대 흡수 에너지인 터프니스 계수를 측정하여 기계적 성질로서 제시하였다. 공기 역학적 성질로서는 땅콩 자실과 종실의 종말속도 및 항력계수가 측정되었다. 1. 땅콩 자실의 기하학적 형상은 수원체로 모형화할 수 있었다. 2. 진밀도는 땅콩 자실의 경우는 515-620 $kg/m^3$, 종실의 경우는 960-1,090 $kg/m^3$, 의 값을 보였다. 3. 대합면이 수평인 자세에서의 파괴력은 영호가 61.9 N, P.I. 314817은 71.5 N, 올 땅콩은 84.8 N였으며, 터프니스 계수는 각각 30, 43, 72 kN-$m/m^3$, 의 값을 보였다. 모든 품종과 함수율에서 파괴력과 터프니스 계수는 대합면이 수직인 자세에서보다 수평자세에서 더 큰 값들을 보였다. 4. 땅콩 자실과 종실의 평균 종말속도는 각각 8.7-9.9 m/s, 10.0-11.6 m/s 범위였다. 종말속도는 진밀도와 직선적인 관계가 있었으며 품종과 형상에 따른 뚜렷한 종말속도의 차이는 보이지 않았다.

  • Agricultural and forest wastes were tested as substrate for the production of Flammulina velutipes. Among the meranti, pine tree, mixed sawdust, coffee waste and peanut hull tested, coffee waste was the best basal substrate for the production of basidiocarps. When various supplements, such as ricebran, brewer's grain, defatted corn flour, defatted soybean flour and defatted rapeseed flour were tested, defatted corn flour was chosen for the production of basidiocarps. Maximum yield of basidiocarps(129.38 g/bottle) was obtained from the mixed medium at 4 : 1 ratio of coffee waste and defatted corn flour.

  • The effect of the addition of various vegetable oils on the mycelial growth was studied. Most vegetable oils were proved to be stimulative for the mycelial growth, and the best mycelial growth (12 mg/ml) was obtained with the addition of cotton seed oil. Several agricultural wastes i.e., rice straw, peanut hull, sawdust, rice hull, cocoa hull, coffee waste and beer waste were empolyed as substrates for sporophore production of p. sajor-caju. The biological efficiency(BE) for sporophore productions of rice straw and peanut hull were 36.4% and 32.6%, respectively. The highest yield of sporophore was obtained from the mixture of rice straw (50%) and beer waste (50%)(BE 109.6%) followed by peanut hull (50%) and beer waste (50%)(BE; 74.5%).

  • To compare the morphological and cultural characteristics of Cordyceps militaris, forming conditions of artificial fruiting body production were investigated in this experiment. The stroma shapes of artificial fruiting body were confirmed to club and/or stick. However, both shapes were same color as a orange. Perithecia of stroma was semi-egg shape and was ranged from $30{\sim}90{\times}90{\sim}130\;{\mu}m$ and it's asci was narrowly cylindric. Ascospore of perithecia was belong to filiform and multiseptate. The conidia of C. militaris was centurally grown and shaped with globose, long clavate type, floccose, centrally raised during anamorph stage. When it was cultured between glass and PP bottle, production of artificial fruiting body, pinheading ratio and total yield were higher in PP bottle. The optimum illumination was 1,000 lx for the those production. The culture medium of barley, wheat and hulled rice showed higher artificial fruiting body compared to that of silkworm. Pinheading and yield of it's isolates was decreased at more than three subsequent transculture.
