Probiotics의 최근연구동향 = Recently research trend of probiotics

국문 초록 (Abstract)

Probiotics는 "장내균종을 개선시켜 줌으로써 숙주동물에게 유익한 영향을 주는 것", "사람 또는 동물 장내 미생물의 균형을 개선시켜 숙주에 효과를 주는 살아있는 미생물 단독 또는 혼합배양물"이라는 의미의 용어이다. Probiotics의 조건에는 효능성, 안전성, 안정성, 분리성의 4가지 조건을 만족시켜야 하며, 식품의 상품성 향상, 면역증강, 유해효소의 합성 억제, 유당 불내증 개선, 장내 유해균의 증식 억제, 장내 균총의 정상화 등 다양한 효능을 가지고 있다.
이런 다양한 효능을 가진 probiotics는 건강식품 및 의료용의 소재, 화장용 소재, 사료 첨가제, 생 백신 개발 재료, 천연 항균물질 생산 등 다양한 곳에 응용되어 사용이 가능하다.

다국어 초록 (Multilingual Abstract)

Probiotics are living non-pathogenic micro-organisms, which as food ingredients also beneficially affect host's health. These non-pathogenic micro-organisms may be lactic acid bacteria, such as lactobacilli, lactococci, and bifidobacteria, or yeasts, such as Saccharomyces cerevisiae subspp. boulardii, or bacillus, such as B. subtilis, B. natto, B. licheniformis.
Probiotics were originally used to influence both animal and human health through intestinal microbiota alterations. At present, the specific live microbial food ingredients and their effects on human health are studied both within food matrices and as single or mixed culture preparations.
Probiotics such as lactobacilli have been reported to effect positively, gastrointestinal disorders such as diarrhoea (rotavirus-associated and antibiotic -associated), inflammatory bowel disease, pouchitis, irritable bowel syndrome, colorectal cancer, lactose absorption, Helicobacter pylori infection and constipation and are increasingly used as a treatment modality.
Basic and clinical research should thus be associated to meet the enthusiasm that patients show for a therapeutical approach that they feel to be safer than most drugs currently proposed to them.
