発酵ステップの間に初回刺激及び活性化されたロイテリンを含有する充填微小区画を有する凍結乾燥L.ロイテリ粉剤の製造
増殖培地において更なる200mMの1,2−PDとビタミンC(4g/L)とビタミンB12(1ug/mL)とにより初回刺激される以外は実施例1と同様の製造プロセス。
発酵ステップの間に初回刺激され、凍結乾燥ステップの前のロイテリン形成のために活性化されるロイテリンを含有する充填微小区画を有する凍結乾燥L.ロイテリ粉剤の製造。
増殖培地に更なる200mMの1,2−PDとビタミンC(4g/L)とビタミンB12(1ug/mL)とにより初回刺激される以外は実施例1と同様の製造プロセス。しかし、100mMのグリセロールを発酵期において添加しないが、その代わりに細胞スラリーに添加した後、凍結乾燥設備に輸送する。
活性化ロイテリン産生機構によるL.ロイテリを有する軟膏剤の調製
以下の成分から軟膏剤を調製する:
