Description
すなわち、本発明は以下の構成からなる。
(1)ビフィドバクテリウム属の菌を有効成分とする、IALD産生促進剤。
(2)ビフィドバクテリウム属の菌がビフィドバクテリウム・ロンガムの菌である、上記(1)に記載のIALD産生促進剤。
(3)ビフィドバクテリウム属の菌がSBT−2928(FERM P−10657)である、上記(1)に記載のIALD産生促進剤。
1.1.菌体の準備
表1に示した乳酸菌11株及びビフィドバクテリウム属の菌12株を供試菌として使用した。乳酸菌はMRS液体培地にて、ビフィドバクテリウム属の菌はGAM液体培地にて37℃,16時間静置培養した。各菌体を遠心分離(1,912×g,4℃,10min)にて回収し、1mM MgSO4を含有する100mM リン酸カリウム緩衝液(pH7、以下、緩衝液と呼ぶ)を用いて3回洗浄した。
反応は休止菌体系にて実施した。表1に示したように、菌体懸濁液を供試菌によってO.D.600=3.7〜7.9に調整して、次のA、Bの2つの反応液組成にて37℃で18時間、反応を行った。
反応液組成A:20mM トリプトファン
反応液組成B:20mM トリプトファン and 20mM α−ケトグルタル酸
反応液は遠心分離後(9,100×g,4℃,10min)、上清を回収し、フィルター(0.22μm)にて不溶物を除去したものをHPLC分析サンプルとした。分析はAgilent社の1200シリーズを使用した。溶離液A(95% Milli−Q water,5% Acetonitrile(ACN),0.05% Trifluoroacetic acid(TFA))で平衡化したODSカラム(Hydrosphere C18 粒子径(μm)S−5,細孔径 4.6X250,品番 HS12S05−2546WT,メーカー YMC)に分析サンプルを10μlインジェクトし、流速1ml/minとして溶離液B(5% Milli−Q water,95% ACN,0.05% TFA)の濃度勾配(%B(time):10(0)→50(16)→50(16)→100(16.1)→100(20)→10(20.1)→10(26))により行った。カラムオーブンは40℃とした。分光光度計にてIALDの吸収波長の試験を行った結果、IALDの検出は300nmにおける吸収を利用した。ここで、合成活性(Synthesizing activity)を、反応により生成したIALD合成量(Concentration. ppm)を供試菌のO.D.600の値で割った値と定義する(式1)。
図1、図2より、α−ケトグルタル酸の有無に関わらず、ラクトバチルス属(Lactobacillus)と比較して、ビフィドバクテリウム属の菌(Bifidobacterium属)、特にビフィドバクテリウム・ロンガム(Bifidobacterium longum)のIALD産生能が優れていることが確認できた。また、その中でも特にSBT−2928(FERM P−10657)の効果が大きい事が確認できた。従って、これらのビフィドバクテリウム属の菌を有効成分として、IALD産生促進剤が提供できることが示された。
