The present study investigated the effect of Leuconostoc kimchii GJ2 (Leu. kimchii GJ2), an exopolysaccharide-producing lactic acid bacterium isolated from kimchi, on serum and liver lipid metabolism in rats fed a high-cholesterol diet. Male Sprague-Dawley rats were divided into four groups: a norma...

exopolysaccharides(EPS)란 무엇인가? | 유산균 기능성 물질로 알려진 exopolysaccharides(EPS)는 지난 20여년에 걸쳐서 다양하게 연구가 수행되었는데, EPS는 물에 녹거나 분산되는 긴 사슬의 고분자 중합체로 미생물 세포벽의 일부로서 세포벽 주위에 협막을 형성하거나 세포벽 외부의 점질물(slime) 형태로서 발효 중에 축적되는 미생물의 1차 또는 2차 대사산물인 다당류이다(9). 미생물의 EPS는 에너지원으로 이용되지는 않으나 건조, 식균작용, 원생동물의 습식, 항생제, 독성화합물, 삼투압 스트레스 등과 같은 외부환경으로부터 자신을 보호하는 작용을 하는 것으로 알려졌다(10). | |

EPS는 미생물이 가장 다량으로 생성 하는 다당류이며, 배양액으로부터 회수가 쉽고, 정제비용이 적게 들므로 상업적인 잠재력이 가장 높은 다당류이다(11). | |
김치 유산균이 가지는 건강 증진 기능에는 무엇이 있는가? | 김치 발효에 관여하는 유산균은 유산균과 같은 낙농제품에 들어있는 유산균과 비슷한 정장 및 항암작용, 면역증강 등의 기능을 하므로 대장 건강에 중요한 역할을 한다. 김치 유산균은 면역기능 강화(3), 혈중 콜레스테롤 저하효과(4), 간 기능 항진작용(5), 항암작용(6), 항산화작용(7-8) 등의 다양한 건강 증진 기능을 보이고 있다. |
