The present invention relates to a new strain, Lactobacillus fermentum PL9119, and to a use thereof. Specifically, the new strain, Lactobacillus fermentum PL9119 which survives with respect to about 1,000 lactobacillus strains isolated from a human body, a food, an environment, and the like even at 80°C and a culture fluid thereof have excellent thermal stability, acid resistance, and bile resistance, do not have a risk of antibiotic resistance metastasis, and have superb food poisoning bacteria and anaerobic bacteria growth inhibition, lipase production capacity, and the like. Thus, the Lactobacillus fermentum PL9119 strain and the culture fluid thereof can be used for a health functional additive for various products such as a probiotic, a lactobacillus formulation, a fermented milk product, a health supplement food, a feed additive, a medical product, cosmetics, and the like for enhancing bowel movement and health condition of the bowel. 본 발명의 신규한 균주인 락토바실러스 퍼멘텀() PL9119 균주 및 이의 용도에 관한 것으로, 구체적으로 인체, 식품, 환경 등에서 분리한 유산균 1000여 균주를 대상으로 80℃에서도 생존성을 보이는 신규한 락토바실러스 퍼멘텀() PL9119 균주 및 이의 배양액은 열안정성, 내산성 및 내담즙성이 우수하고 항생제 내성 전이의 위험이 없으며, 식중독균 및 혐기성균 성장 억제능 및 리파제 생산능력 등이 뛰어나므로 상기 락토바실러스 퍼멘텀 PL9119 균주 및 이의 배양액은 배변활동 및 장 건강 상태를 증진시키는 생균제 또는 유산균제제, 발효유제품, 건강보조식품, 사료첨가제, 의약품, 화장품 등의 다양한 제품의 건강기능성 첨가제로 유용하게 사용될 수 있다.
