Antifungal Activity of Oak Vinegar Against Fungi Isolated from Organic Cultural Heritage

유기질 문화재로부터 분리한 곰팡이에 대한 참나무 목초액의 항진균 활성 조사

We have evaluated the antifungal activities of oak vinegar to develop a natural biocide for organic cultural heritage. Fungi used in this study were screened from the cultural heritages, Kyujanggak and JanggyeongPanjeon and tested on organic substrates-degrading ability. In the results, 7 species of fungi have produced the extracellular enzymes to degrade CMC, xylan, lignin. Thus, we have used these seven species fungi to investigate the antifungal activity of oak vinegar in this study. In the result, the antifungal activity of oak vinegar indicated positive potencial. Especially, methylene chloride and ethylacetate fractions of the oak vinegar had high activities at the concentration of 5.0mg/disc. In these fractions, many different kinds of compounds such as phenolic and furfural, etc. were analyzed by GC-MS. The experiments indicated that the development of a biocide using natural extracts can have a potential to conserve of organic cultural heritages.
