Beschreibung
Zusammenfassung:	The present invention relates to Lactobacillus fermentum JY563 with enhanced exopolysaccharide production, alcohol decomposition activity, and antioxidant activity. The strain of the present invention has improved exopolysaccharide production and can be applied to various industries by solving the low production of the existing parent strain. In addition, the present invention has increased alcohol decomposition activity and antioxidant activity, so that it can be used as a health food such as probiotic preparations and hangover relievers. Also, since the strain has not been improved through gene editing or inclusion, it has the advantage that the stability is recognized. 본 발명은 엑소폴리사카라이드 생산량 및 알코올 분해활성 및 항산화 활성이 증진된 돌연변이 균주 락토바실러스 퍼멘텀(Lactobacillus fermentum) JY563에 관한 것으로, 본 발명의 균주는 엑소폴리사카라이드의 생성성이 향상되어 기존 모균주의 낮은 생산량을 해결하여 다양한 산업에 적용이 가능하다. 또한, 알코올 분해활성 및 항산화 활성이 증가하여 프로바이오틱스 제제 및 숙취해소제 등의 건강식품으로 활용할 수 있다. 게다가 유전자 편집 및 산입으로 균주 개량된 것이 아니기 때문에 안정성이 인정되는 장점이 있다.
