  • The changes in components and biological activities of doenjang samples prepared with black soybeans and fermented with Bacillus subtilis SCB were investigated. The amino nitrogen (A-N) contents of samples increased with increasing black soybean content. A doenjang product made using a 1:1 ratio of soybeans-black soybeans showed a maximum level of genistein and daidzein isoflavones ($1111.6{\mu}g/g$) at 110 days of fermentation, along with decreasing contents of genistin and daidzin due to the conversion to aglycones. The black soybean-only doenjang sample showed higher protease activity, including caseinolytic and fibrinolytic enzyme activities, than the other samples, and had relatively higher polyphenol content and DPPH radical scavenging activity. Therefore, doenjang made with additions of black soybeans and fermented by B. subtilis SCB may have improved physiological properties, suggesting this to be a valuable method of preparation.

  • In this study, alcohol fermentation condition for production of plum wine was investigated and further, sensory evaluation and nutraceutical properties of the plum wine and liquors were also determined. Ethanol was produced maximally when 5% Saccharomyces cerevisiae was added in red plum juices and fermented at $25^{\circ}C$ for 5 days. Among the red plum wine and various kinds of plum liquors, red plum wine showed the best acceptability and its ACE inhibitory activity, fibrinolytic activity and antioxidant activity were also excellent.

  • Urokinase, a plasminogen activator, was conjugated with dextran by the cyanogen bromide activation-coupling method. The resulting water-soluble conjugate was purified by gel permeation chromatography on Sephadex G-200. The maximal activity was obtained when the ratio of urokinase/dextran was 1/20 for the coupling. The final preparation showed 5 CTA units/mg conjugate, 300 CTA units/mg protein, 8.4 % activity retention, and 47 % protein retention. The urokinase-dextran conjugate had good thermal, pH and storage stabilities. In addition, it showed greater resistance to the inhibitory effect of human plasma than native urokinase. Also in vitro biological half-life of urokinase increased 40 times by this conjugation. In view of activity, excellent stability and increased half-life, the conjugate can be a potential fibrinolytic agent in an injectable form.

  • This study was carried out to examine Electron donating ability (EDA), nitrite scavenging, tyrosinase inhibition, ACE inhibition activity and fibrinolytic activity of culture extracts from Phellinus linteus which was grown added rice bran, pine needles and turmeric in brown rice. Electron donating ability of Phellinus linteus extract (PLE) was lower in the water extract than the ethanol extract. Nitrite scavenging activity was the highest in PLE from ethanol extract than water extract. Especially, when the pine needles was addition treatment, the nitrite scavenging activity was about 70% at pH 1.2 by ethanol extract. Tyrosinase inhibition activity of PLE was highest in the water extract than ethanol extract, and inhibition rate was the most higher in the extract by hot water added pine needles. ACE inhibition activity were very low effective at water and ethanol extract. Fibrinolytic activities were similarly strong in rice bran, pine needles and turmeric powder. Especially, when rice bran was added, showed the activity was increased about 5% than plasmin. Therefore, It may be used for the food industry as natural source of bioactive compound after further investigation, such as in vivo experiment.

  • Metalloenzyme was purified from the fruiting bodies of Tricholoma sejunctum. MALDI-TOF and ICP/MS analyses revealed that the enzyme had a molecular weight of 18788.25 and includes $Zn^{2+}$ ion. The N-terminal amino acid sequence of the enzyme was Ala-Thr-Tyr-Lys-Ile-X-Ser-Ala-Thr-His-Gln-X-X-Leu-Val. The activity of the enzyme was inhibited by EDTA and 1,10-phenanthroline, indicating that the enzyme was a metalloprotease. No inhibition was found with E-64 and pepstatin. It has broad substrate specificity for synthetic peptides. The enzyme was stable up to $40^{\circ}C$. The activity of the enzyme was increased by $Zn^{2+}$ and $Co^{2+}$, while it was totally inhibited by $Hg^{2+}$. The enzyme hydrolyzes $A{\alpha}$ subunit of human fibrinogen but did not show any reactivity for $B{\beta}$ and ${\gamma}$ form of human fibrinogen.

  • In this study, the biological activities of aqueous, ethanol, and methanol extracts of larvae of the edible insect Protaetia brevitarsis seulensis, fermented using several kinds of microorganisms, were tested in in vitro experimental models. Six effective microorganisms were used for fermentation, namely Lactobacillus plantarum JBMI F3, Lactobacillus plantarum JBMI F5, Lactobacillus gasseri Ba9, Aspergillus kawachii KCCM 32819, Saccharomyces cerevisiae KACC 93023, and Bacillus subtilis KACC 91157. Biological activities (${\alpha},{\alpha}^{\prime}-diphenyl-{\beta}-picrylhydrazyl$ [DPPH] free radical scavenging activity, reducing power, and fibrinolytic activity), and biochemical properties (phenolic compounds and flavonoids) were examined in aqueous, ethanol, and methanol extracts from P. brevitarsis seulensis powder and fermented P. brevitarsis seulensis powder. The total phenolic compounds and flavonoid contents were highest in the aqueous extract of B. subtilis-fermented P. brevitarsis seulensis powder. DPPH radical scavenging activity and reducing power were stronger in the fermented group than the nonfermented group. Fibrinolytic activity were highest in the extract from B. subtilis-fermented P. brevitarsis seulensis powder. The ${\alpha}-amylase$ activity in starch was higher in the fermented group than the nonfermented group, but there was no significant difference. These results provide basic data to understand the biological activities of bioactive materials derived from fermented P. brevitarsis seulensis larvae for the development of functional foods.

  • To develop a new Gugija(Lycium chinensis Mill) product having increased value, the physiological functionality of various commercial Gugija products were investigated. In addition, an in vivo study was performed using spontaneous hypertensive rats(SHR) to examine the anti-hypertension effects of products. The results showed that antioxidant activity was highest in the methanol extract of Gugija leaf pickle(97.7%), and anti-hypertensive angiotensin I -converting enzyme(ACE) inhibitory activity was 80.4% in Gugija doenjang(soybean paste) water extract. Anti-cholesterolemia HMG-CoA reductase inhibitory activity was highest in the methanol extract of Gugija rice cake(66.1 %). However, SOD-like activity was below 30% in most products; and fibrinolytic activity was not detected or was very weak. Ultimately, we selected Gugija tea and Gugija wine as superior anti-hypertensive Gugija products, and subsequent in vivo testing was performed using SHR, comparing the tea and wine to Gugija fruit. Among them, the Gugija fruit demonstrated the best anti-hypertension effects in SHR.
