Description
1.ビフィドバクテリウム・ブレーベ N708株(NITE BP-02958)
本発明のビフィズス菌はビフィドバクテリウム・ブレーベ(Bifidobacterium breve)である。本発明におけるN708の記号は、日清食品ホールディングス株式会社で独自に菌株に付与した番号である。本発明の菌株は、乳児糞便より本発明者によって初めて分離されたものである。
(1)寄託機関名:独立行政法人製品評価技術基盤機構 特許微生物寄託センター
(2)連絡先:〒292-0818 千葉県木更津市かずさ鎌足2-5-8 122号室
(3)受託番号:NITE BP-02958
(4)識別のための表示:N708
(5)寄託日:2019年5月29日
本発明のビフィドバクテリウム・ブレーベ N708株は、後述する実験例に示すように、抗炎症性のIL-10産生誘導能が高く、なお且つ炎症性のIL-12産生誘導能が低い菌株である。IL-10およびIL-12産生誘導能の評価については、以下の試験方法によって実施した。
IL-10およびIL-12産生誘導能評価試験に用いた被験体(死菌紛末)は、ビフィズス菌を表3に示すGAM培地(ニッスイ)で37℃・24時間、前培養と本培養をした。次いで、増殖した本培養液中の菌体を遠心分離して集菌し、分離した菌体を滅菌水で3回洗浄し、加熱殺菌後、凍結した。その後、凍結乾燥機を用いて凍結乾燥をすることで、乾燥死菌体粉末を得た。
本発明の菌株のIL-10およびIL-12産生誘導能を評価するために、ヒト末梢血CD14+単球をロンザジャパン株式会社より購入し、参考文献(Monika et al., Regulation of the IL-10/IL-12 axis in human dendritic cells with probiotic bacteria. (2011) FEMS Immunol Med Microbiol. 63:93-107.)に従い樹状細胞に分化誘導した。すなわち、ヒト末梢血CD14+単球を20 ng/mL GM-CS (Granulocyte Macrophage colony-stimulating Factor), 20 ng/mL IL-4 10%FBSおよび10%FBS含有RPMI-1640培地にて、37℃、5%CO2条件下で6日間培養することにより樹状細胞に分化誘導した。細胞回収後に細胞数を調整し、96穴培養プレートに1 × 105細胞/wellずつ分注した。そこに上記で得た乾燥死菌体粉末を100 ng/mLとなる様に添加後37℃、5%CO2条件下で6時間培養した。さらに、IL-12p70誘導剤 (0.1 μL/mL Lioppollysaccuaride、20 ng/mL IFN-γおよび50 ng/mL TNF-α)を添加して18時間培養した。なお、IL-12p70誘導剤が添加された樹状細胞は、ストレス環境下におかれると炎症性サイトカインであるIL-12p70の産生が高まる。本発明では、ストレス環境下に樹状細胞をおいても、IL-10の産生を促進し、なお且つIL-12の産生を促進しない菌株を探索する目的で、樹状細胞にIL-12p70誘導剤を添加した。培養後培養上清を回収し、培養上清中のIL-10はIL-10 Human Uncoated ELISA Kit (Invitrogen)により、IL-12はHuman IL-12p70 Uncoated ELISA (Invitrogen)によりそれぞれ測定した。
本発明のビフィズス菌は飲食品に含有せしめて使用することができる。本発明のビフィズス菌は特に飲料に好適に用いることができるが、例えば、発酵乳及び乳酸菌飲料が考えられる。現行の乳及び乳製品の成分規格等に関する省令では、成分規格として発酵乳(無脂乳固形分8.0%以上のもの)や乳製品乳酸菌飲料(無脂乳固形分3.0%以上のもの)であれば1.0×107 cfu/mL以上、乳酸菌飲料(無脂乳固形分3.0%未満のもの)であれば1.0×106 cfu/mL以上必要とされるが、乳などのはっ酵液中で増殖させたり、最終製品の形態で増殖させたりすることによって上記の菌数を実現することができる。また、ビフィズス菌入りの発酵乳及び乳酸菌飲料以外にも、バター等の乳製品、マヨネーズ等の卵加工品、バターケーキ等の菓子パン類等にも利用することができる。また、即席麺やクッキー等の加工食品にも好適に利用することができる。上記の他、本発明の食品は、前記ビフィズス菌と共に、必要に応じて適当な担体及び添加剤を添加して製剤化された形態(例えば、粉末、顆粒、カプセル、錠剤等)であってもよい。
本発明のBifidobacterium breve N708株と、自社保有の3株のBifidobacterium breve比較菌株(Bbr1, Bbr2, Bbr3)及び標準株のBifidobacterium breve JCM1192についてIL-10およびIL-12産生誘導能を評価した。
本発明のビフィドバクテリウム・ブレーベ N708株と標準株であるBifidobacterium breve JCM1192について、スキムミルク培地増殖性試験を実施した。
