고구마의 새로운 이용방법으로 고구마의 기능성을 활용한 고구마 된장을 제조하였다. 고구마 페이스트와 대두분말을 1:1로 혼합하여 펠렛을 제조한 다음 황국균을 접종, 배양하여 효소활성이 높은 고구마 황국을 제조하였고, 제조한 신황미와 신자미 황국(20, 45%)에 증자대두와 식염 10%를 혼합, 60일간 발효 숙성하여 저염 고구마 된장을 제조하였다. 고구마 된장에는 감칠맛 성분인 글루탐산이 일반된장보다 많은 양 함유되어 있었고 숙성에 의해 항산화활성이 증가하였으며, DPPH 라디칼 소거활성($EC_{50}$)은 신자미 황국을 45% 혼합한 신자미 된장에서 0.9 mg으로 가장 높았다. 관능평가에서 신황미 황국을 45% 혼합한 신황미 된장의 선호도가 가장 좋았다.

Aspergillus oryzae, Bacillus subtilis 및 Bacillus natto를 접종하여 만든 메주와 재래식메주로 된장을 각각 담금한 후 숙성과정중의 성분을 조사한 결과는 다음과 같다. 아미노태 질소함량은 Aspergillus oryzae구와 재래식 메주구가 Bacillus subtilis구와 Bacillus natto구에 비하여 월등히 높았다. 총당, 환원당은 재래식 메주구가 다소 많았고 pH는 Aspergillus oryzae구가 경시적으로 pH 5.0이상을 나타냈으나 Bacillus subtilis구는 4.5미만으로 pH저하가 심하였다. 숙성 90일 된장의 유리아미노산 중 Asp. Thr. Ser. Glu. Gly. Ala. Cys. Val. Met. Leu. Lys. His.은 Aspergillus oryzae구의 된장에서 Tyr. Arg. Pro.은 재래식구의 뒨장에서, Ileu. Phe.의 함량은 Bacillus subtilits구의 된장에서 각각 높게 나타났으며 유리아미노산의 총량은 Aspergillus oryzae구가 타시험구보다 월등히 높았다.

This study evaluated the effects of dietary inclusion of soybean (SM) and fermented soybean meal (FSM) on growth promotion in juvenile abalone Haliotis discus. Six hundred and thirty juvenile abalone were distributed into nine plastic containers. Three diets were prepared with 22% fish meal, 2% casein, and either 25% SM or FSM used as the protein sources in the experimental diets, and Undaria was used as a control diet to compare the effects of the experimental diets on the growth performance of abalone. The diets were assigned to three containers each and fed to the abalone once daily to satiation for 16 weeks. Weight gain and specific growth rate (SGR) were higher in abalone fed the SM diet than in those fed the FSM diet. Weight gain and SGR of abalone fed the SM and FSM diets were higher than those of abalone fed Undaria. The crude protein and lipid contents of the edible portions of abalone fed the SM and FSM diets were higher than those of abalone fed Undaria. SM was superior to FSM as a protein source in abalone feed. The SM and FSM diets facilitated greater growth than Undaria.

The objective of this study was to improve the qualities of Saengsik (substitute meal formulated with uncooked cereal powder) such as functionality, safety and sensory preference by using Lactic Acid Bacteria (LAB). The optimum formulation of fermented Saengsik (substitute meal) was verified as $40\%$ of fermented brown rice, $13\%$ of fermented job tears, $5\%$ of yellow soybean, $5\%$ of waxy rice, $5\%$ of sorghum, $3\%$ of Seumok bean, $1\%$ of sesame, $3\%$ of barley, $2\%$ of red bean, $5\%$ of prosomillet, $2\%$ of foxtail millet, $9%$ of black rice, $3\%$ of buckwheat, $1\%$ of chestnut, $2\%$ of pumpkin, $3\%$ of peanut. Fermented Saengsik decreased significantly serum glucose in STZ-induced diabetic rats. However, serum lipid levels were not affected by fermented Saengsik. In rats fed with high-fat diet, serum triglyceride level was slightly decreased and the contents of liver triglyceride were significantly decreased by supplementation of fermented Saengsik.

전통발효식품인 된장으로부터 높은 활성의 fibrinolytic enzyme를 생산하는 미생물을 수십 종 분리하였다. 산업적으로 우수한 균종을 선별하기 위하여 분리된 미생물중 fibrinolytic enzyme활성과 성장 속도면에서 가장 우수한 균주를 선별하여 하였으며, 형태학적, 생화학적 및 생리학적 특성을 조사한 후 Bacillus sp.로 동정되었다. Fibrinolytic enzyme생산을 위한 최적 배양조건은 초기 pH $6\~8$일 때 상대활성도가 $80\%$이상을 나타내었고, 배양 12시간째에 가장 높은 활성도를 나타내었다. Fibrin plate를 이용한 혈전용해능을 확인한 결과 높은 혈전용해능을 가지고 있었다. 탄소원으로 galactose를 $4\%$ 첨가 하였을 때 가장 우수하였으며, 질소원은 malt extract를 $4\%$ 첨가 하였을 때 가장 우수하였다. 무기염은 $K_2HPO_4$를 첨가하였을 때 가장 우수한 활성을 나타내었다.

The objectives of present study were to characterize the peptides which were isolated from Korean fermented soybean paste, chungkukjang, and to determine their antioxidant activities. Four fractions were collected from the methanol extract of chungkukjang by using a recycling preparative HPLC. Among fractions, Fr-2 was identified to be highly potent free radical scavenging activity in the assay of 1,1-diphenyl-2-picryl-hydrazyl (DPPH) and nitroblue tetrazolium(NBT)-reduction inhibition. Base on antioxidant effects, fraction Fr-2 was employed for the refraction with a prep-column and separated into five fractions of which two fractions were identified to have higher antioxidant activity. To confirm the amino acid constituents of antioxidant fractions Fr-2-2 and Fr-2-3 were analyzed, and eight kinds of amino acids such as aspartic acid, threonine, serine, glutamic acid, glycine, lysine, histidine, and arginine were identified as the constituent amino acids. Antioxidant activities of the separated peptides were further assessed cell viability with 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl terazolium bromide (MTT), and fluorescence-activated cell sorting (FACS) analysis of H4IIE cells treated with hydrogen peroxide (H2O2). Chungkukjang peptides have shown their ability to protect H4IIE rat hepatoma cells against H2O2- induced oxidative stress by concentration and time-dependent manner. Therefore, These results indicated that fermented soybean paste chungkukjang will be promoted the antioxidant and radical scavenging activities, and beneficial for health. The antioxidant peptide fractions Fr-2-2 and Fr-2-3 were denominated as P-NICS-1 and P-NICS-2, respectively. However, further studies were required to clarify their amino acid sequences and molecular properties, and physiological significances.
