Yogurt is a product of the acidic fermentation of milk, which affects the survival of lactic acid bacteria (LAB). The aim of this present study was to examine the survival and acid stress response of Lactobacillus rhamnosus GG to low pH environment. The survival of LAB in commercial yogurt was measu...

Probiotics로 널리 알려진 미생물은 무엇인가? | Probiotics로 가장 널리 이용되는 미생물로 Lactobacillus 속, Bifidobacterium 속 그리고 비병원성 효모인 Saccharomyces boulardii(Kligler and Cohrssen, 2008)를 들 수 있으며, 이들 미생물들은 국내에서 정장작용을 하는 대표적인 건강기능 식품으로 인식되어 왔다. | |
Lactobacillus rahmnosus GG의 인체 내 유익한 특성은 무엇인가? | LGG는 인체에서 발견되는 여러 균주들 중 여러 가지 인체에 유익한 특성(장 상피세포 부착능, 내산성과 내담즙성, 독성 세균에 대한 항균물질의 분비능)이 가장 탁월하다고 알려졌다. 또한 LGG는 장에서 IgA 분비능을 증가시킨다든지, 소화관에서 장 점막의 보호역할을 하고 있는 점액의 성분을 바꾸어 장내에서 장벽으로 작용하게 한다는 등 장 질환 관련 유용성에 대한 실험적 가설이 제시되어 있으며, 동물실험 및 임상실험으로 꾸준히 연구되고 있다. | |
Lactobacillus rahmnosus GG을 처음 발견하게 된 계기는? | 종류가 다른 Probiotics는 그 효과도 다른 것으로 알려져 있다. 내산성이 높고 장내 정착성이 우수한 것으로 알려져 있는 Lactobacillus rahmnosus GG(LGG)는 1985년 Gorbach 교수와 Goldin 교수에 의해 성인의 분변에서 처음 분리되었다. 오늘날 이 미생물은 전 세계에서 가장 연구가 많이 된 probiotics이다. |
