고한수,조대희,황성연,김영만 한국식품영양학회 1999 韓國食品營養學會誌 Vol.12 No.1

청국장 제조를 위한 분리균은 포자형성율이 높은 Bacillus subtilis로 대사력이 활발한 대수증식기의 것을 콩에 1,000CFU/g 이상의 균수를 접종하여 40℃와 상대습도 90%에서 배양하면 발효가 빠르게 진행되었다. 발효가 종료되면 포자형성율이 95% 이상 되어야 저온의 후숙과정에서 재번식이 쉽게 일어나지 않았으며 발효취는 발효 중에서만 형성되었다. 중립콩과 대립콩의 발효율이 가장 좋았다. 저온의 후숙과정은 5℃에서 1∼2일 후 경과하면 Bacillus subtilis는 더 이상의 증식이 일어나지 않고 발효취가 소멸되므로 저온의 유통과정을 거쳐야 불쾌취가 없는 구수한 청국장의 맛을 유지할 수 있었다. The strain isolated for making chungkuk-jang was Bacillus subtilis, which formed spore with 98% ratio. Logarithmical culture was inoculated (1,000 CFU /g) to the steamed soybeans and at the optimum fermentation conditions(40℃, RH 90%), fermentation progressed very rapidly and synchronously. Fermentation time was 24 hours on the optimum fermentation conditions. During activated fermentation, chungkuk-jang's aroma and flavor created. After finishing the fermentation, the spore forming ratio was 95% and replenishment was not occured easily during aging at the below 5℃.

S-2 (3-aminopropylamino)ethylphosphorothioic acid (WR-2721)이 방사선에 대한 방어효과에 미치는 영향을 규명하고자 Sprague-Dawley계 웅성 흰쥐를 대조군, WR-2721 단독투여군 (200㎎/㎏), X-선 단독조사군, WR-2721투여 (200㎎/㎏)후 X-선 조사한 병용군으로 나누어 X-선 8 Gy선량을 전신조사한 후 1,3,7,10일 간에 각각 혈액을 채취하여 효소활성치와 glucose함량 변화를 측정하여 다음과 같은 결과를 얻었다. X-선 단독조사군에서는 ALP와 AST의 활성치가 대조군에 비하여 감소하였으나 WR-2721 을 병용한 군에서는 그 감소폭이 줄어들었고, ALT와 LDH의 활성치는 X-선 단독조사군에서 대조군에 비하여 증가하였고, WR-2721을 병용한 군에서는 그 증가폭이 감소되었다. 또한 glucose치의 변동은 X-선 단독조사군에서 대조군에 비하여 유의성 있게 증가하였으나 WR-2721을 병용한 군에서는 그 증가폭이 감소되었다. 이로 미루어 보아 WR-2721이 X-선으로부터 생체내 주요 장기들을 보호하는 작용이 있음을 시사하고 있다. Male rats of Albino strain were divided into four groups, control group, X-irradiated group, WR-2721 treatment group and X-irradiated group treated with WR-2721. The radioprotective effect of treatment with S-2 (3-aminopropylamino)ethylphosphorothioic acid (WR-2721) in the dose of 200㎎/㎏ by intraperitonial injection on rats 20min prior to wholebody X-irradiation (8Gy) was studied. Each group determined serum alkaline phosphatase (ALP), aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH) activities and contents of serum glucose after 1, 3, 7 and 10 days. The ALP and AST activities of X-irradiated group were significantly decreased (p<0.05) compared with that of control group, but X-irradated group treated with WR-2721 less decreased those enzyme activities compared with the X-irradiated group. X-irradiated group was significantly increased (p<0.05) ALT and LDH activities compared with that of control group, but X-irradated group treated with WR-2721 less increased those enzyme activities compared with the X-irradiated group. The concentration of serum glucose of X-irradiated group was signficantly increased (p<0.05) compared with that of control group, but X-irradated group treated with WR-2721 less increased compared with that of X-irradiated group. It may be considered that WR-2721 provided radioprotective effect of organs of body from X-irradiation.

This paper proposes a measurement method for the surface of micro-parts by using AFM(Atomic Force Microscope). To this end, two techniques are presented to extend the capacity of AFM. First, the measurement range is extended by using an image matching method based on correlation coefficients. To account for the inaccuracy of the coarse stage implemented in AFM's, the image matching technique is applied to two neighboring images intentionally overlapped with each other. Second, a method to measure the shape of relatively large specimen is presented by using the inherent trigger mechanism due to the atomic force. The proposed method is proved effective through a series of experiments.

Mandarine orange (Citrus unshiu Marc.) only added with sugar was fermented by effective microorganisms (EM). called "EM-fermented orange". EM was mainly composed of lactic acid bacteria. phototrophic bacteria and yeast. As pH of EM-fermented orange reached 3.5 to 4.0 in the course of fermentation. the incubation was stopped. and then. EM-fermented orange was preservable at room temperature for about 6 months. Composition and concentration of free amino acids in EM-fermented orange were analyzed. Concentration of total amino acids was 167 mg/l. and the relative content of carnosine (β-alanyl-L-histidine) which was well known as a kind of antioxidant materials was very high. 41%. In addition. crude extract showing antioxidant activity could be obtained from EM-fermented orange using some organic solvents. The antioxidant activity of the crude extract was equivalent to about 9% of that of vitamin E by the use of 1.1-diphenyl-2-picrylhydrazyl (DPPH) method. It was suggested that EM-fermented orange having antioxidant characteristics could promote the health of fish.
