Description
(1)ポリウレタンを分解する作用を有する、シュードザイマ属に属する酵母であるBS−UE5株(FERM P−20243)。
(2)ポリウレタンをシュードザイマ属に属する酵母であるBS−UE5株(FERM P−20243)で微生物分解する方法。
(3)前記ポリウレタンがエステル系のポリウレタンであることを特徴とする(2)に記載の方法。
(4)前記ポリウレタンがポリウレタンフォームであることを特徴とする(2)又は(3)に記載の方法。
本発明は新規微生物であるシュードザイマ属の酵母BS−UE5株である。また本発明はポリウレタンを上記微生物で分解する方法である。従来ポリウレタンの微生物による分解は知られており、カビや細菌の例は報告されているが、酵母による分解の報告は知られていなかった。また、従来の微生物分解ではポリウレタン以外に酵母抽出物などの炭素源を加えた例が多く、ポリウレタンを唯一の炭素源とする微生物分解の例は少ない。
