Abstract
Description
本発明者らが保有する乳酸菌のうち、主に植物性乳酸菌である約480株(JCM株を含む)について、人工腸液における増殖能を評価した。
<人工腸液(pH6.45)>
MRS培地 9mL
10w/v%胆汁(和光純薬工業株式会社)溶液 1mL
1w/v%パンクレアチン(from Porcine:SIGMA) 100μL
なお、胆汁溶液及びパンクレアチン溶液は0.22μmのフィルター(PVDF membrane、Millipore社製)で処理することにより無菌にしたものを用いた。
高脂肪食を自由摂取させたマウスに以下のように調製したTUA4337L株を投与して、排泄される菌数を定量した。具体的には、以下のように調製した投与サンプルを用いて、乳酸菌約10億cells(1.0×109cells)分(菌体懸濁液250μLに相当)をC57BL/6Jマウス(10週齢、雄)に午前10時ごろに1回投与した(n=5)。
<投与サンプル(生菌含有サンプル)の調製>
〔1〕TUA4337L株のグリセロールストックから、MRS培地(30mL)へ1v/v%植菌
〔2〕培養(35℃、20hr)
〔3〕培養液を遠心(8000rpm、5min)して上清除去後、PBS(−)30mLで懸濁
〔4〕〔3〕の懸濁液を遠心(8000rpm、5min)して上清除去後、PBS(−)5mLで再懸濁
〔5〕顕微鏡で菌数カウント
〔6〕15mLの遠心管に200億cells分の溶液を分取し、遠心(8000rpm、5min)して上清除去後、液状飼料(高脂肪食 60kcal%FAT:Research Diet)5mLに懸濁して菌体懸濁液を調製(液状飼料はPBS(−)で調製)
<リアルタイムPCRによる菌数測定法>
〔1〕糞便100mg(湿重量)に対してPBS(−)1mLを添加後、スパチュラーを用いて解砕
〔2〕糞便100mg分をエッペンチューブ(登録商標)に採取後、遠心(15000rpm、5min)して上清除去後、PBS(−)1mLで懸濁(遠心から懸濁までの操作を2回繰り返す)
〔3〕〔2〕の懸濁液から上清除去後、キット(QIAamp DNA Stool Mini Kit:キアゲン)を用いてDNAを抽出
(細胞破砕は、Glass beads(150〜212μm:SIGMA)300mg、phenol/chloroform/isoamylalcohol(25:24:1)300μL、及びbuffer ASL(キット中の試薬)900μLを添加し、MULTI−BEADS SHOCKER MB−200(YASUI KIKAI)で3000rpm、1min遠心後、氷上1min静置の操作を3回繰り返すことで行う)
〔4〕下記に示す条件のリアルタイムPCRにより腸管内容物中の乳酸菌を定量
((リアルタイムPCR条件))
(1) SYBR Premix Ex Taq ll(Takara Bio)10μL、each primer(10μM)0.8μL、ROX reference DyeII 0.4μL、滅菌水6μL、DNA溶液2μLを混合してPCR反応液を調製する。プライマーはラクトバチルス・ペントーサス及びラクトバチルス・プランタラムの16S rDNAを特異的に検出する以下のプライマーを用いる(ラクトバチルス・ペントーサスとラクトバチルス・プランタラムの16S rDNAの配列は100%同一である)。
primer1:5’-GCAAGTCGAACGAACTCTGGTATT-3’(配列番号2)
primer2:5’-CGGACCATGCGGTCCAA-3’(配列番号3)
(2) PCRは7500 Real Time PCR System(Applied Biosystems)を用いて、95℃ 30秒の後、95℃ 5秒、60℃ 34秒を1サイクルとして、合計60サイクル反応を行い、得られた蛍光強度と腸管内容物合計量と希釈倍率から腸管内容物1g当りのコピー数を求める。
(3) 別途1cell当たりの16S rDNAのコピー数を求め、菌数に換算する。なお、乳酸菌を投与していないマウスにおいては、前記リアルタイムPCRによりラクトバチルス・ペントーサス及びラクトバチルス・プランタラムのいずれも検出されないことを確認する。
C57BL/6Jマウス(8週齢、雄)を、通常食群、高脂肪食群、高脂肪食+生菌群、高脂肪食+死菌群の4群に群分けし(各n=10)、それぞれに以下の表5に示す食餌を32日間続け、体重を毎日測定して平均値を算出した。平均値の推移を図2に示す。なお、群間比較は、有意水準0.05によるt検定を用いて行った。
〔1〕TUA4337L株のグリセロールストックから、MRS培地(30mL)へ1v/v%植菌
〔2〕培養(35℃、20hr)
〔3〕培養液を遠心(8000rpm、5min)して上清除去後、PBS(−)30mLで懸濁
〔4〕〔3〕の懸濁液を遠心(8000rpm、5min)して上清除去後、PBS(−)5mLで再懸濁
〔5〕顕微鏡で菌数カウント
〔6〕15mLの遠心管に200億cells分の溶液を分取し、遠心(8000rpm、5min)して上清除去後、人工胃液(125mM NaCl、7mM KCl、pH1.0)5mLを添加して攪拌後60min放置
〔7〕〔6〕の溶液を遠心(8000rpm、5min)して上清除去後、液状飼料(60kcal%FAT)5mLで懸濁して菌体懸濁液を調製
実施例3における通常食群、高脂肪食群、高脂肪食+生菌群の群構成で(各n=12)、それぞれに実施例3と同じ内容の食餌を2週間続けた。その後、一晩絶食させた後、オリーブオイル(nacalai tesque)を投与し(5mL/kg)、さらに3時間後に解剖して大静脈から血清を採取した。血清中のトリグリセライド(TG)をトリグリセライド E−テストワコー(和光純薬工業株式会社)を用いて測定した。結果を図3に示す。なお、群間比較は、有意水準0.05によるt検定による有意差判定を行った。
配列表の配列番号2は、ラクトバチルス・ペントーサス/プランタラム特異的プライマーの塩基配列である。
配列表の配列番号3は、ラクトバチルス・ペントーサス/プランタラム特異的プライマーの塩基配列である。
