Fungal floras were investigated for the lysimeter soil treated with municipal sewage sludge (MSS), pig manure compost (PMC), industrial sewage sludge (ISS), leather processing sludge (LS), and alcohol fermentation processing sludge (FS). Fungal populations were higher in the FS, ISS, LS, or MSS-treated soil than in the chemical fertilizer-treated soil. Isolated fungi from the sewage sludge were identified as Penicillium spp., Gliocladium spp., Acremonium spp., Trichoderma spp., Aspergillus spp., Blastomyces spp., and Phoma spp.

EP was obtained through 20% ethanol extraction of Pueraria lobata root, and the fermented form of EP, FEP, was prepared from the EP after incubating with Lactobacillus rhamnosus vitaP1. There was no significant toxicity by EP and FEP up to $1000{\mu}g/ml$ in NIH-3T3, HaCaT, and B16F10 cells. In addition to antioxidant potentials of EP and FEP determined by DPPH and ABST assays, we confirmed increase of procollagen type I and elastin synthesis by supplementation of the EP and FEP at the concentration of $50{\mu}g/ml$ using ELISA kits. The protein expression levels of matrix metalloprotease (MMP)-1, -3, and -9, those are involved in the degradation of collagen or other skin matrix proteins, were remarkably suppressed while their inhibitory protein metallopeptidase inhibitor 1 (TIMP-1) was greatly up-regulated by supplementation of the EP and FEP at a concentration of $50{\mu}g/ml$. Taken together, both EP and FEP supplementation could be involved in the suppression of the skin wrinkle formation through inhibiting degradation of collagen and stimulating the synthesis of collagen and elastin. The results showed that the anti-wrinkle potential of the EP and FEP will be a promising candidate for developing cosmeceutical compounds or products.

Chaga mushroom and Cheonggukjang have been used in alternative medicine. In this study, we determined the anti-obesity effects of fermented Chaga-Cheonggukjang (FCC), an extract prepared by secondary fermentation of a mixture of Cheonggukjang and Chaga by Lactobacillus acidophilus on highfat diet (HFD)-induced mice. Male ICR mice were fed a normal diet or HFD in the presence or absence of 3% and 5% FCC (FCC3 and FCC5). After 3 months, the mice were sacrificed, and serum and tissue samples were examined. Body weight and epididymal fat pad (EFP) weight were significantly lowered in FCC3 and FCC5 groups compared to those in the HFD control group. FCC supplementation suppressed serum triglyceride (TG) and increased serum HDL levels. Serum GOT, GPT, leptin levels and hepatic COX-2 mRNA expression were significantly higher in the HFD groups, and these increases were significantly attenuated by FCC supplementation. FCC suppressed body weight and EFP weight gain, as well as inflammatory responses in the liver in HFD-fed mice. Thus, FCC supplementation may have protective effects for obesity-related disease.

Background and objective: This study was conducted to find out the effects of healing farm resources and participant satisfaction on the level of stress and loyalty. Methods: The experiment was conducted on 18 subjects who participated in agro-healing activities (aged 49.5 years on average) and the concentration of cortisol, the level of stress and satisfaction with the services and program of a healing farm. The healing-agriculture activities were performed once a week, a total of 7 sessions, for 90 minutes and their saliva was collected before and after the activities. Results: The concentration of cortisol, a stress hormone, was statistically significantly reduced after the healing-agriculture activities in 5 out of 7 sessions. The total cortisol concentration showed statistically significant differences. The 6th session was comprised of different activities, compared to others, such as understanding weeds, managing a garden and making a pizza with fermentation enzymes, and the level of cortisol in the 6th session was the lowest after participating in the agro-healing activities, which indicated that the activities have the positive effect of lowering the level of stress. The level of stress was lowered from 18.39 to 16.78, which was consistent with the results of the concentration of cortisol. The level of satisfaction in the last session was below 50%, which indicated that the owner of the farm might be a little inexperienced in education and marketing on information and safety. The variables of participants including stress and satisfaction with services showed a strong influence on their loyalty. Conclusion: Satisfaction with services and loyalty to the healing farm showed a very high correlation, which was statistically significant. It also showed that participants' stress level and satisfaction with the services and program of the healing farm have a strong influence on their loyalty.

To determine the deacidification factor during carbonic maceration (CM), different temperature conditions were studied. The pH was higher in CM-$35^{\circ}C$ and CM-$25^{\circ}C$ and was lower in CM-$45^{\circ}C$. The total acid was inversely related to the pH. The malic-acid level decreased much more in CM-$35^{\circ}C$ than in CM-$45^{\circ}C$ while the lactic-acid level increased much more in CM-$35^{\circ}C$. The activity of the NADP-malic enzyme, which catalyzes the oxidative decarboxylation of L-malate into pyruvate, $CO_2$, and NADPH, was higher in CM-$25^{\circ}C$ and CM-$35^{\circ}C$ while CM-$45^{\circ}C$ showed no NADP-malic enzyme activity. The malic-dehydrogenase (MDH) activity was higher in CM-$25^{\circ}C$ and CM-$35^{\circ}C$ while CM-$45^{\circ}C$ showed no MDH activity. The oxalacetate decarboxylase activity was similar to the NADP-malic-enzyme and MDH activities. Pyruvate decarboxylase activity was shown in all the CM treatments. The L-lactic dehydrogenase (LDH) activity was not explored in the fermentation of pyruvate to lactate via LDH in the grapes during CM. In this study, it was confirmed that carbonic maceration reduced the malic acid during fermentation and was affected by the temperature. Moreover, it was assumed that the deacidification during the carbonic maceration of the grapes was probably correlated with the degradation enzyme activity of malic acid.

Artemisia princeps Pampanini (AP) was fermented with Bifidobacterium infantis K-525 and its antiasthmic effect investigated. AP and fennented AP (FAP) reduced the IgE level in the blood of ovalbumin-induced asthmic mice. Moreover, FAP reduced the IgE, proinflammatory cytokine IL-6, and IL-4 levels in the trachea, as well as in the lung of the experimental asthmic mice, whereas AP only reduced the IgE and IL-6 levels in the lungs. Nonetheless, AP and FAP both inhibited the mRNA expression of IL-6 and TNF-${\alpha}$ in IgE-induced RBL-2H3 cells. The in vivo antiasthmic effect of FAP was more potent than that of AP. Therefore, these findings suggest that the enhanced antiasthmic effect of AP after bifidus fermentation was possibly due to the regulation of the proinflammatory cytokine biosynthesis of IL-6 and TNF-${\alpha}$.

This study sought to prepare Doenjang with added Ulmi cortex, to improve functionality and flavor, while retaining the original Doenjang scent. Ulmi cortex powders were added during fermentation. The Ulmi cortex-containing Doenjang showed lower pH and less salinity than did the Doenjang prepared without Ulmi cortex. Sensory evaluation data showed that Doenjang with Ulmi cortex tasted sweeter, and less salty, and was preferred over Doenjang without Ulmi cortex. In the DPPH assay, Doenjang with Ulmi cortex showed much higher free-radical scavenging ability (IC50 of 29.16 g/mL)did Doenjang without Ulmi cortex(IC50 of 155.67 g/mL), indicating that Ulmi cortex Doenjang has higher antioxidant levels. Doenjang prepared with 1%(w/v) Ulmi cortex powder was best in terms of consumer preference and functionality.

Bobsikhae and Bellflower tea-added Bobsikhae samples were prepared. Their general ingredients and useful ingredients were analyzed. Among the general ingredients of the two samples, the crude protein, crude fat, crude ash, and carbonhydrate contents, but not the water, were found to have been higher in the Bellflower tea-added Bobsikhae. To summarize all the results of this study by comparing Bobsikhae with Bellflower tea-added Bobsikhae that used the Bellflower root with edible and medicinal values, their general ingredient contents were similar, but the lactic acid bacteria all tended to be higher in the Bellflower tea-added Bobsikhae. The results of the sensory evaluation showed that the overall taste and general acceptability were better in the Bellflower tea-added Bobsikhae than in the Bobsikhae. Thus, the Bellflower tea-added Bobsikhae is considered ideal for further commercialization. However, it was determined that further studies will be required to show if the bioactive substance would be influenced by the fermentation in the production progress of the Bellflower tea. Such findings and their application to the product development are expected to contribute much to the popularization of Bobsikhae.

Objectives : This study is to effect of improving muscle atrophy through water extract on the solid-phase fermentation extraction with Phellinus linteus of discarded Schisandra chinensis in an atorvastatin-induced atrophy C2C12 cell. Methods : C2C12 myoblast were differentiated into myotube by 2% horse serum medium for 6 days, and then treated solid-phase fermentation(S-P) extract at different concentrations for 24h. To investigate the effect of S-P extract on the induction of muscle atrophy and expression of atrophy-related genes and apoptosis in differentiated C2C12 myotubes using a GSH, ROS, real-time PCR, western blots analysis. Results : As a result of treatment with atorvastatin at concentrations of 5, 10, and 20 uM on the 6th day of differentiation in C2C12 myotube cells, it was confirmed that the cell morphology was damaged in a concentration-dependent manner, and the length and thickness of the myotube also decreased in a concentration-dependent manner. Treatment with S-P extract (50, 100 and 200 ㎍/㎖) increased of GSH and inhibited ROS in the atorvastatin-induced muscle atrophy cell model at a concentration that did not induce toxicity. In addition, it was confirmed that it has an effect on muscle reduction by inhibiting apoptosis of muscle cells as well as being involved in protein production and degradation of muscle cells. Conclusions : Atorvastatin-induced atrophy C2C12 cell, S-P extract activates related to differentiation/generation and proteolysis, and inhibits cell death of atrophy in C2C12 cell. Based on this, it is necessary to prove its effectiveness through animal models and human application test, but it is considered to be discarded Schisandra chinensis can present the potential for development as a recycling industrial material.

The purpose of this study was to investigate changes in the contents of constituents in Sipjundaebo-tang (SJ) and its fermentations (FSJ) with 8 species of lactic acid bacteria. Eight strains of lactic acid bacteria, Lactobacillus casei KFRI129, L. plantarum KFRI 144, L. curvatus KFRI 166, L. hilgardii KFRI 229, L. delbruekil subsp. lactis KFRI 442, L. casei KFRI 692, L. gasseri KCTC 3163, and Bifidobacterium breve KFRI 744, were utilized for the fermentation of Sipjundaebo-tang. As a result we identified three constituents which increased and two constituents which decreased. The increased constituents were isolated by chromatographic techniques and then their structure elucidated using NMR and MS. The decreased constituents were confirmed by comparing standard compounds. These compounds were quantitatively analyzed using the HPLC/DAD system. The increased constituents were identified to be cinnamyl alcohol (1), liquiritigenin (3), and nodakenetin (5), while the decreased constituents were liquiritin (2) and nodakenin (4). Generally, liquiritin (2) and nodakenin (4) were noted as having decreased in fermented Sipjundaebo-tangs (FSJs), while cinnamyl alcohol (1), liquiritigenin (3), and nodakenetin (5) were seen to have increased. Sipjundaebo-tang fermented by L. plantarum KFRI144 exhibited the most remarkable changes in all of fermentations. The eight lactic acid bacteria all demonstrated differing decomposable rates on the five maker compounds in fermented Sipjundaebo-tang (FSJ).
