        A recycling soap was prepared from non-cooking oils. The effects of physical and chemical properties of the recycling soap on biodegradation are expected to be different due to the thermal histories of the non-cooking oils. Therefore, the biodegradation rate of the recycling soap was studied by using Klebsiella pneumoniae(K. pneumoniae), and the growth rate of K.pneumoniae in soap solution was observed. The biodegradation rate of the recycling soap appeared to be slower as the thermal histories of the non-cooking oils became larger. This might be resulted from hydrolysis, in which the ester bonds in the oils are broken to produce hydroxyl group. It was also observed that the growth rate of the microorganism decreased with the increase in the thermal histories of the oils. As a result, it is desired that recycling soap should be produced from the non-cooking oils with the proper ranges of thermal histories to reduce water contamination. The non-cooking oils with larger thermal histories are considered to be recycling through the cracking process before used.

        들깨관련 종·속 수집 유전자원 들깨(Perilla frutescens var. japonica Hara), 자소(Perilla frutescens var. acuta Kudo), 축면자소(Perilla frutescens var. crispa Decaisne), 청자소(Perilla frutescens var. Kudo for viridis Makino), 들깨풀(Mosla punctulata Nakai), 산들깨(Mosla japonica Maxim) 및 쥐깨풀(Mosla dianthera Maxim)에 대한 잎품질 및 지방산 조성을 조사한 결과를 요약하면 아래와 같다. 1. 수집한 들깨관련 종·속 가운데 Perilla속 유전자원이 Mosla속 유전자원보다 주경엽수가 많았고 길이에서 3배 정도, 폭에서 약 5배 정도 컸었다. 2. 들깨관련 종·속 모든 수집 유전자원이 들깨보다 방향성 정도가 높아 방향성 개량육종의 교배재료로서 활용가치가 기대된다. 3. 잎의 유연성 면에서는 Perilla속 유전자원이 Mosla 속 유전자원보다 부드러웠다. 4. 종실성분함양에서 들깨에 비하여 들깨관련 수집 종·속의 기름과 단백질함량이 낮았으나 리놀렌산 함량이 높아서 공업용 또는 의약용을 위한 고리놀렌산 들깨품종개량의 교배재료로 활용가치가 기대된다. 5. 수집 Perilla속 유전자원의 불포화지방산인 리놀렌산과 기름함량, 단백질함량 그리고 포화지방산과는 부의 상관을 보였다.

        Methane production from grain dust was studied using a 3 L laboratory-scale anaerobic plug flow digester. The digester was operated at; temperature of 35, 45, and 55℃ hydraulic retention time(HRT) of 6 and 12 days; and influent concentration(S_0) of 7.8 and 9.0 % total solids(%TS). With ten different operation conditions, this study showed the significant effects of temperature, hydraulic retention time, and influent concentration on methane production, The highest methane-production rate achieved was 1.903 (L methane) /(L digester)(day) at 55℃, 6 days HRT, and S_0 of 7.8 %TS. A total of 3.767 L of biogas per day with a methane content of 50.57% was obtained from this condition. The ultimate methane yield(B_0 was found to be a function of temperature and influent concentration, and was described as : B_0= 0.02907T-0.1263-0.00297(T-10)(%TS), where TS is the total solids in the liquid effluent, and T is temperature(℃). Our results showed that thermophilic condition is better than mesophilic for grain dust stabilization in an anaerobic plug flow digester.

        Apexes of basidia in Rhodophyllus(synonyum of Entoloma) muraii var. albus are divided into four sections or depressed in the center. A spore is formed by inflation of the apex of the sterigma. The apex of the sterigma is swollen and changed from a papilla through a penisform and a club into a globeform. Six spots of globose spore are regularly or irregularly depressed with hilum axes. Finally the spores are cuboid. Basidia of Entoloma squamiferrum are developed from hymenium layer of crator-shaped parabasidium. Apex of basidium is flat or depressed in the center. Although four sterigmata are developed, only two sterigmata are symmetrically swollen to two spores in certain basidia. It means that two sterigmata among four sterigmata are infertile. The apex of the sterigma is swollen into a paillaform, and then turned into a penisform. It is swollen from a clubform into a globeform. Six spots of the surfaces of globose spore are deperssed with hilum axes. Finally the spore is cuboid, and then it is released from hilum. Four sterigmata of papillaform of E. violaceobrunneum are developed from cartor-shaped basidium. The apex of sterigma is swollen to a small globeform. And then it is swollen to a clubform. The clubform is again swollen to a ellipticalform, and then more than six spots of spore surfaces are ramomly depressed with hium axes. When the depression of surface of a elliptical spore is over, it is the multi-angular spore of the heterometrical-form.
