  • P.sajor-caju의 균사체 생장에 oil 첨가효과를 검토한 결과 대부분의 식물성 oil 에서 좋은 결과를 보였으며, 그 중 cotton seed oil을 배지 100ml에 2.5ml 첨가하였을 때 균체량이 무첨가구에 비하여 약 4배정도 이었다. 자실체 생산 기질로 농산 및 산업폐기물인 볏짚, 땅콩박, 왕겨, 톱밥 ,코코아박, 맥주박, 커피박 등을 사용한 결과 볏짚의 biological efficiency(B.E.)가 36.4%였으며 땅콩박은 32.6%로 나타났다. 또한 볏짚(50%)과 맥주박(50%)을 혼합하였을 경우 B.E가 109.6%로 최고치를 나타냈으며 땅콩박(50%)과 맥주박(50%)을 혼합하였을 경우에도 B.E.가 74.5%로 높은 수확량을 나타내었다.

  • This study was carried out to investigate the effect of soil covering materials such as rice bran, rice hull and saw dust on garlic growth through a field experiment in wintertime. Rice bran was the smallest in term of particle size, but it recorded the highest level of bulk density. The missing plant rate after winter season was relatively high, 59.3%, and that of soil covering materials stood at the low level of 10%. Other growth factors recorded the highest level during application of rice bran. In terms of chemical properties of soil-covering materials, rice bran recorded the highest level of 1.84, 2.34 and 0.16% in the content of N, P, and K, respectively. The subsoil temperature was higher by application of rice bran as compared to that of other materials which stood at the lowest temperature ($-9^{\circ}C$).

  • 본 연구의 목적은 바이오차를 미생물 담체로 활용하기 위해 pH 조절제로서 구연산과 목초액을 각각 처리한 왕겨 바이오차와 어분을 혼합한 토양 침출수의 양분 용출 패턴을 구명하기 위해 수행하였다. 왕겨 바이오차 pH 6.0~7.0와 어분을 혼합비(4:6)로 조제하였다. 본 실험의 처리는 산도를 조절하지 않은 바이오차 처리한 토양을 대조구(RB+DF), 목초액으로 산도 조절한 왕겨 바이오차와 어분의 혼합물(RBP+DF)을 처리한 토양, 구연산으로 산도 조절한 왕겨 바이오차와 어분의 혼합물(RBC+DF)을 처리한 토양 3 수준으로 구성되어 있다. 왕겨 바이오차와 어분을 혼합한 토양 침출수 중에 NH4-N, NO3-N, PO4-P, K의 농도를 분광계를 이용하여 분석하였다. 실험 결과로서 RBC+DF 처리한 토양의 침출수 중에 NH4-N와 PO4-P 누적함량은 가장 높았고, 또한 RBP+DF를 처리한 토양의 침출수에서 NO3-N와 K의 누적함량은 가장 높게 나타났다. 대조구에 비해 NH4-N와 PO4-P는 구연산으로 산도를 조절한 왕겨 바이오차를 처리한 토양의 침출수에서, NO3-N와 K는 목초액으로 조절한 왕겨 바이오차 처리한 토양의 침출수에서 각각 흡착능이 낮아 더 많이 용출되는 것으로 관측되었다. 따라서, 미생물 담체로서 산도를 조절한 왕겨 바이오차의 시용에 따른 작물 생육 반응에 관한 연구가 필요하다고 판단된다.

  • 1. Amino acid compositions were determined by amino acid analyzer. Through the analysis of these samples, it was found that glutamic acid was the most abundant; glycine, aspartic acid, lysine and threonine were rich; and tryptophan and methionine were the limiting amino acid. 2. Albumins, globulins, gliadins and glutelins were extracted from the Kangwon hull, Kangwon rice buckwheat, and wheat. The relative proportions of protein fractions were 52.45 : 10.14 : 16.61 : 20.80% in Kangwon hull buckwheat, 21.10 : 13.80 : 28.40 : 36.70% in Kangwon rice buckwheat and 6.87 : 1.65 : 42.85 : 48.6% in wheat, in the order of albumins, globulins, gliadins and glutelins. 3. Polyacrylamide gel electrophoresis (PAGE) and SDS-polyacrylamide gel electrophoresis (SDS-PAGE) were performed to identify the subfractions of each protein fraction. The electrophoregrams of PAGE showed that the same fractions of both Kangwon hull buckwheat protein and Kangwon rice buckwheat protein had very similar electrophoretic patterns to each other respectively, but there were significant differences in the patterns between buckwheat proteins and wheat proteins.

  • High surface area and high pore volume activated carbon was prepared by KOH activation of rice hull. The electrodes were fabricated by compounding the commercial and rice hull activated carbons with PVdF and PVdF-PVP mixed binders without addition of conductivity improver. The electrodes fabricated with rice hull activated carbon and PVdF-PVP mixed binders showed the best performance because the PVP played as a pore-forming agent. The electrode exhibited excellent electrochemical characteristics having 7.9 W.h/kg of energy density, 33.5 F/g of speific capacitance, 0.7 $\Omega$ of ESR and good efficiency of self-discharge compared with that fabricated with commercial activated carbons.

  • Antimicrobial activities of the Acidic Liquid originated from Carbonized Rice Hull(ALCRH) and the paper treated with ALCRH were investigated to apply ALCRH to functional paper products as a natural antimicrobial agent. ALCRH showed antimicrobial activity for bacteria and yeast, with higher performance for bacteria than for yeast. Antimicrobial activity was not developed on paper coated with ALCRH by bar coater probably due to the evaporation of antimicrobial compounds of ALCRH from the paper surface with time. Saturation of paper with ALCRH was essential to develop antimicrobial activity on the paper. Dipping paper in ALCRH solution was recommended as one of the effective ways to make antimicrobial paper.

  • We examined the effect of the acidic liquid from carbonized rice hull(ALCRH) treatments to molded fiber packages(MFP) on weight, Haugh unit, pH and microbial activity of egg to extend the shelf life in egg packaging. Higher concentration and surface spray treatment of the acidic liquid extended the shelf life of egg. ALCRH treatment to MFP improved the performance of the packaging for egg in terms of decreased weight loss and retarded microorganism growth of eggs during storage.

  • The main purpose of this study is to seek desalinization effect of subsurface drainage system with rice hull packing in Dae-Ho Reclaimed Land. After 4 years installed sub-surface drainage system, distribution of drained water electric conductivity (ECw) was 4.43~12.78 ds/m. The soil profile showed partial development of the soil structure and compaction of subsoils with increased bulk density. The bulk density of the subsoil was 1.42~1.66 g/cm$^3$, which might limit root growth. The soil color changed near the drainage pipe line. Distribution of soil extract solution ECe and SAR as subsurface drainage pipe position and drainage canal distance showed desalinization effect of subsurface drainage system with rice hull packing as widening effective zone of subsurface drainage pipe.
