Description
bacto Trypton 1重量%、bacto yeast extract 0.5重量%、及び塩化ナトリウム0.5重量%を含む液体培地を作製し、pH7.2に調整して、120℃で20分間高圧蒸気滅菌した後、至適生育温度30℃のシュードモナス・フラギ(Pseudomonas fragi) 株(NBRC 3458) の1白金耳を液体培地に接種し、回転型振とう機で、27℃で150rpmの攪拌下、24時間培養した。培養後、4℃、6,000rpmで20分間遠心分離することにより菌体を除去しリパーゼ液を得た。この液のリパーゼ活性は1〜3U/mlであった。
前記実施例1〜3で用いたリパーゼ液に代えて、至適生育温度24℃のRhizopus・oryzae属の微生物から産出されたリパーゼの1重量%水性液(pH7.1)10mlを用いた外は、実施例1〜3、参考例2、4と同様にしてフィルムの分解性を評価し、結果を表1に示した。
Claims (3)
- 廃棄すべき脂肪族或いは脂環式ジオールと脂肪族或いは脂環式ジカルボン酸とからなるポリエステル系樹脂を、該ポリエステル系樹脂の分解能を有し、至適生育温度が35℃以下の微生物から産出された酵素に20℃未満の温度条件下で接触させて分解する分解処理方法において、該微生物がシュードモナス(Pseudomonas) 属に属する菌株であり、且つ、該微生物から産出された酵素がリパーゼであることを特徴とするポリエステル系樹脂の分解処理方法。
- 酵素を、酵素を含有する水性液としてポリエステル系樹脂に接触させる請求項1に記載のポリエステル系樹脂の分解処理方法。
- ポリエステル系樹脂が、脂肪族或いは脂環式ポリエステル樹脂である請求項1又は2のいずれかに記載のポリエステル系樹脂の分解処理方法。
