Zusammenfassung:	The present invention relates to a novel strain of Galactomyces candidum derived from Dendropanax morbifera which has excellent acid resistance and exhibits laccase activity, a method of fermenting an extract of Dendropanax morbifera without sugar, and fermentation liquid of the extract of Dendropanax morbifera, which is obtained by thereby and from which urushiol, an allergy-causing substance is removed and antioxidant function is maintained. The Galactomyces candidum C27 (Den-1) strain of the present invention has excellent acid resistance and can grow in strong acid, and exhibit lacase activity and can remove uriciol, an allergy-causing substance. Thus, it is possible to ferment the extract of Dendropanax morbifera by using the strain of Galactomyces candidum C27 (Den-1) of the present invention such that the antioxidant effect is maintained while the allergy-inducing substance is eliminated. In addition, by using the stain, the extract of Dendropanax morbifera can be fermented without adding sugar, so that various adult diseases can be prevented. Accordingly, it is expected that the fermented liquid of the extract of Dendropanax morbifera, which is fermented by using the strain, can be effectively used in various foods such as yogurt, beverage, etc. without causing allergies or adult diseases. 본 발명은 산 내성(acid tolerance)이 우수하면서 라카아제(laccase) 활성을 가지는 황칠나무 유래 새로운 갈락토마이세스 칸디듐() 균주 및 이를 이용하여 황칠나무 추출물을 무가당 발효시키는 방법, 및 이에 따라 수득된 알러지 유발물질인 우르시올이 제거되고 항산화 기능이 유지된 황칠나무 추출물의 발효액에 관한 것으로, 본 발명의C27(Den-1) 균주는 산 내성이 우수하여 강산에서도 생육이 가능하고, 라카아제 활성이 우수하여 알러지 유발물질인 우르시올을 제거할 수 있다. 따라서, 본 발명의C27(Den-1) 균주를 이용하여 강산의 황칠나무 추출물을 발효시킬 수 있으며, 알러지 유발은 제거되면서도 고유의 항산화 효과는 유지시킬 수 있다. 또한, 상기 균주를 이용하여 추가의 당 첨가 없이 황칠나무 추출물을 발효시킬 수 있어 각종 성인병을 예방할 수 있다는 이점도 있다. 이에 따라, 상기 균주를 이용하여 발효된 황칠나무 추출물의 발효액은 알러지 또는 성인병 등의 유발에 대한 부담 없이 요구르트, 음료 등 각종 식품에 유용하게 이용될 수 있을 것으로 기대된다.
