As for this invention, from as for details, it is separated from the breast milk of the Korean woman in regard to the lactobacillus which is separated from the breast milk of the human, purobaioteitsuku activity such as resistance to acid, resistance bile characteristic and anti-bacterial activity and rakutobachirusu gatsuseri which possesses the effect of weight increase control (Lactobacillus gasseri) it regards the BNR17 strain. It possesses the high anti-bacterial activity where rakutobachirusu gatsuseri BNR17 of this invention, confronts resistance to acid, resistance bile characteristic, and adhesion activity and the bacterial characteristic microbe for the intestinal cell, synthesizing in the polysaccharide which the digestion enzyme cannot disassemble the monosaccharide component in the food which the human takes in, it possesses the effect of weight increase control by making discharge to outside the body. By this kind of numerous beneficial function, the strain of this invention can be used the fermented milk or the various fermentation products, not only the fodder additive of the animal, effectively to also the raw germ formulation and the food auxiliary additive in order to prevent weight increase.本発明は、人間の母乳から分離した乳酸菌に関し、より詳しくは、韓国女性の母乳から分離され、耐酸性、耐胆汁性及び抗菌活性等のプロバイオティック活性と体重増加抑制の効果を有するラクトバチルス・ガッセリー(Lactobacillus gasseri)BNR17菌株に関する。本発明のラクトバチルス・ガッセリー BNR17は、耐酸性、耐胆汁性、及び腸細胞に対する付着活性と、細菌性微生物に対する高い抗菌活性を有し、人間が摂取する食べ物中の単糖類成分を、消化酵素が分解することができない多糖類に合成して体外へ排出させることにより、体重増加抑制の効果を有する。このような幾多の有益な機能により、本発明の菌株は発酵乳及び多様な発酵製品、動物の飼料添加剤だけでなく、体重増加を防止するための生菌製剤及び食品補助添加剤にも有効に用いられ得る。
