Description
1.ラクトコッカス・ラクティスT21株(NITE BP-02164)
本発明の乳酸菌は、ラクトコッカス・ラクティス(lactococcus lactis)である。特にラクトコッカス・ラクティスに属する乳酸菌のうち、ラクトコッカス・ラクティスT21株である。本発明にいうT21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。本ラクトコッカス・ラクティスT21株はクランベリーより本発明者の一人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−02164
(4)識別のための表示:T21
(5)原寄託日:2015年11月20日
(6)ブダペスト条約に基づく寄託への移管日:2016年10月12日
本発明のラクトコッカス・ラクティスT21株の菌学的性質は、以下の表1及び2に示す通りである。本菌学的性質は、Bergey’s manual of systematic bacteriology Vol.2(1986)に記載の方法による。
本発明のラクトコッカス・ラクティスT21株は、後述する実験例に示すように、高い免疫調節作用、すなわちIL-12の高い産生誘導能力を有する。IL-12の産生誘導能力の確認については以下の試験方法によって行った。
菌体を表3に示すMRS培地(Difco Lactobacilli MRS Broth)で30℃ ・48時間培養した。次いで、増殖した菌体を遠心分離して集菌し、分離した菌体を滅菌水にて3回洗浄し、凍結した。その後、凍結乾燥機を用いて凍結乾燥し、乾燥菌体粉末を得た。
IL-12産生誘導評価では、細胞としてマウス由来マクロファージ様細胞株であるJ774.1細胞を使用した。はじめに、10%の非動化FBS(Invitrogen)とPenicillin-Streptomycin(Invitrogen)、NaHCO3(Sigma)、L- glutamine(Invitrogen)を加えたRPMI1640培地(日水製薬)を用いて、J774.1細胞を37℃ CO2 5%の条件下で培養した。そして、24穴の培養プレートの1穴ごとに2.5×105 cells/mlのJ774.1細胞を2mlずつ加え、そこに上記で得た乾燥菌体粉末をJ774.1細胞培養培地で0.1 mg/mlの濃度になるよう懸濁して100μl添加し37℃ 5%CO2条件下で24時間培養した。培養後培地を回収し3500 rpmで2分間遠心分離を行い、培養上清を得た。Mouse Total IL-12 ELISA kit(Thermo scientific)を用いて培養上清中のIL-12を測定した。
<スキムミルク培地増殖性試験>
前培養液を10%SM(スキムミルク)培地に植菌し、これを30℃ ・48時間培養し、乳酸菌数、pHによってミルク培地での増殖性を評価した。
本発明の乳酸菌は飲食品に含有せしめて使用することができる。本発明の乳酸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産生誘導能力/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1.0×106cfn/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、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、前記乳酸菌と共に、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。
<試験例1>IL-12産生誘導評価
本発明のラクトコッカス・ラクティスT21株と、自社保有の3つのラクトコッカス・ラクティス比較菌株(LL1、LL2、LL3)についてIL-12産生誘導評価を実施した。
本発明のラクトコッカス・ラクティスT21株と、自社保有の3つのラクトコッカス・ラクティス比較菌株(LL1、LL2、LL3)について、スキムミルク培地増殖性試験を実施した。
Claims (3)
