Description
本発明に用いられる2層のシームレスカプセルは、生体触媒を油性物質に懸濁した懸濁組成物でなる内層、および水透過性基材を含む皮膜組成物でなる外層で構成される。
内層は、生体触媒を油性物質に懸濁した懸濁組成物でなる。生体触媒は特に制限されない。水性液状物の存在下、すなわち外層−油層−水層の偽三層構造において、反応が活性化されるものであればよく、例えば、バイオリアクタなどの反応素子として用いられるものが挙げられる。具体的には、酵素、微生物(乳酸菌など)、動物細胞(ランゲルハンス島、脂肪細胞など)、植物細胞(脱分化カルスなど)、植物組織(不定胚、不定芽、多芽体、茎頂、生長点、プロトコルム様体、不定根、毛状根など)などが用いられる。生体触媒は、単独で用いてもよいし、あるいは2種以上を組み合わせて用いてもよい。
外層は、水透過性基材を含み、必要に応じて、その他の成分を含み得る皮膜組成物でなる。そのため、外層は水性液状物を透過し、かつ得られる2層のシームレスカプセルを水性液状物に浸漬した場合に、カプセル内部に水性液状物が取り込まれる程度の伸縮性を有する。水透過性基材は、好ましくはゲル化剤および光硬化性樹脂の少なくとも1種であり、これによって得られる皮膜は、水性液状物の透過性が高い。さらに、皮膜自体の水による膨潤は大きくないが、適度な伸縮性を有し、シームレスカプセル内部に水性液状物を容易に取り込むことができる。本明細書において、水性液状物とは、水または水性成分を含む水溶液を示す。水性成分とは、生体触媒の基質となり得る水溶性成分であり、生体触媒の種類に応じて適宜選択される。水性成分としては、例えば、培地成分(炭素源、窒素源、ミネラルなどを含む)が挙げられる。
ゲル化剤としては、カラギーナン、寒天、グルコマンナン、アルギン酸、ゲランガム、ザンサンガム、ローカストビーンガム、ペクチン、サイリウムシードガム、グアーガム、ファーセレラン、アラビノガラクタン、アラビノキシラン、アラビアガム、デキストリン、変性デキストリン、デンプン、化工デンプン、プルラン、カルボキシメチルセルロース塩などの多糖類が挙げられる。好ましくは、カラギーナン、寒天、グルコマンナン、およびアルギン酸である。ゲル化剤は、皮膜組成物中に固形分濃度で、好ましくは0.1〜40質量%、より好ましくは0.3〜30質量%含有される。
光硬化性樹脂は、光照射により引き起こされる反応により硬化する樹脂であり、通常、光重合性モノマー、光重合性オリゴマー、または光重合性モノマー若しくは光重合性オリゴマーの付加重合物が用いられる。光硬化性樹脂は、単独で用いてもよいし、あるいは2種以上組合わせて用いてもよい。光硬化性樹脂は、重合開始剤と組合わせて用いることが好ましい。
皮膜組成物に含まれ得るその他の成分としては、例えば、ゲル化助剤、不飽和結合を有する水溶性化合物、重合開始剤、光増感剤、着色剤、および細孔形成剤が挙げられる。ゲル化剤を用いる場合には、ゲル化助剤を用いることが好ましい。光硬化性樹脂を用いる場合は、重合開始剤、特に光重合開始剤を用いることが好ましい。
上記2層のシームレスカプセル(図1(a))は、例えば、同心二重ノズルを備えるカプセル製造装置を用いた液中滴下法、具体的には、最内側から第1ノズルおよび第2ノズルを有する同心二重ノズルを備えるカプセル製造装置を用い、該第1ノズルから、生体触媒を油性物質に懸濁した懸濁組成物を、そして該第2ノズルから水透過性基材を含む皮膜組成物を同時に液中に押出す工程を包含する方法などにより調製される。液としては、液状の油性物質(液状油)、例えば、0〜40℃で液体の上述の油性物質などが用いられる。この液は、好ましくは冷却して用いられる。
本発明のシームレスカプセルは、上記2層のシームレスカプセルを、水性液状物に浸漬させることによって得られる。水性液状物としては、例えば、上述のような水、あるいは液体培地などの水性成分を含む水溶液が用いられる。水性液状物の量は、シームレスカプセルが浸漬できる量であればよく特に制限されない。浸漬条件についても、特に制限されない。シームレスカプセルに含まれる生体触媒の失活を防止する観点から、例えば、4〜60℃にて1時間〜60日間で行われる。効率的に水性液状物を封入できる点で攪拌することが好ましい。
皮膜組成物として、40%ENTG−3800(関西ペイント株式会社製)水溶液60質量部、アセトイン0.6質量部、および0.5%ポバール(平均分子量約9,000)水溶液20質量部の混合物を準備した。油性物質として、大豆油100質量部および流動パラフィン20質量部の混合物を準備し、この油性物質に、平均分子量約1,000のデキストリン20質量部を懸濁し、懸濁組成物を調製した。
ポバールの代わりにポビドン(平均分子量約1,300,000)を用いて皮膜組成物を調製したこと、および平均分子量約1,000のデキストリンの代わりに平均分子量約120,000のプルランを用いて懸濁組成物を調製したこと以外は、実施例1と同様にして、粒径4mmのシームレスカプセルを得た。さらに実施例1と同様にして、プルラン濃度の経時変化を測定した。結果を表2に示す。なお、攪拌終了時において、破れたシームレスカプセルはなかった。
皮膜組成物として、40%ENT−3400(関西ペイント株式会社製)水溶液80質量部およびベンゾインイソブチルエーテル0.6質量部の混合物を準備した。油性物質として、大豆油100質量部および流動パラフィン20質量部の混合物を準備し、この油性物質に、平均分子量約1,000のデキストリン20質量部を懸濁し、懸濁組成物を調製した。
乳酸菌(Lactococcus lactis subsp. lactis JCM 7638)を、大理石を含むデマン・ロゴサ・シャープ(MRS)ブイヨン培地(オキソイド社製)を用いて37℃にて15時間静置培養した。得られた培養懸濁液の生菌数は、1.5×1010cfu/mLであった。なお、cfuは、colony forming unitの略語であり、生菌数を表す。この培養懸濁液を10,000xgの条件下で4℃にて20分間遠心分離し、得られた沈殿物を凍結乾燥して乳酸菌末を調製した。
皮膜組成物として、40%ENT−3400(関西ペイント株式会社製)水溶液60質量部、ベンゾインイソブチルエーテル0.6質量部、および1%アクリロイルモルフォリン(株式会社興人製)水溶液20質量部の混合物を準備した。油性物質として、大豆油100質量部および流動パラフィン20質量部の混合物を準備し、この油性物質に、圧搾パン酵母(オリエンタル酵母株式会社製)20質量部を懸濁し、懸濁組成物を調製した。上記の皮膜組成物および懸濁組成物を、参考例1と同様にして、同心二重ノズルを有するカプセル製造装置を用いて射出し、液滴(2層のシームレスカプセル)を得た。
