        As the hangover relieving drink market has been expanded, there have been efforts to produce traditional drinks that can be easily taken through reducing material costs after finding materials with high alcohol-degrading activity from agricultural products and manufacturing drinks in a way to produce sikhye. Studies were made to know quality, the ability to relieve hangover and preference of drinks for which seven kinds of agricultural products, including shiitake mushrooms, were added in the forms of fresh juice, extracts and powder. Farm products showed the highest acetaldehyde dehydrogenase (ALDH) when they were added in the form of powder before saccharification and shiitake mushrooms showed the highest enzyme activity when they were added in the form of powder. When added in the form of powder, people showed the lowest preference except when radish and hericium erinaceum were added. When bear puree was added to a mixture of powdered shiitake mushrooms, radish, bean sprouts and dadagi cucumber, enzyme activity got higher and people showed higher preference. An experiment of animal behaviors showed that the mixture had a high ability to relieve hangover in one or two hours after 10% or 40% alcohol was orally administered to mice due to long traveling distance of mice.

        Background : Ginseng widely cultivated as a major medicinal herb in Korea, is economically important crop for farmer. Ginseng root disease caused by soil borne pathogens is main factors restricting the quantity and quality of ginseng. The disease can result in harvest loss of up to 20~70% and limits the replanting of ginseng under same field for long time. The traditional control method of agrochemical use is not recommend to control soil borne disease because of difficulty in use and unstable effect. The objective of this study was to evaluate the efficacy of several antagonistic microbes for developing biological control method of ginseng root rot. Methods and Results : To select biocontrol agents against ginseng soil borne disease, several bacteria were isolated from ginseng root and rhizosphere soil evaluated in vitro screening of antifungal bacterial against ginseng root pathogens. Two antagonistic bacteria, ES17 and CJ4, showed the strongest inhibition effect against ginseng root pathogen. In the pot experiment under greenhouse conditions, ginseng seedling dipped in bacterial suspension at inoculum density of 106 cfu/ml for 1 hour were planted in pot containing inoculum. Control effect was examined depend on disease severity index at 30 days after inoculation. Ginseng root treated with CJ4 and ES17 isolate reduced root rot disease development on the ginseng root with degrees of control efficacy of 85% and 70%, respectively. Conclusion : Two biocontrol agent, Burkholderia ambifaria CJ4 and Paenibacillus strain ES17, had strong antifungal efficacy against ginseng soil borne pathogens. These results obtained from in vitro test and pot experiment suggest the potential applicability of the biocontrol agent to control ginseng root rot caused by various soil borne pathogens.
