耐高温曲霉属(Aspergillussp.)分离到一株能降解聚己内酯薄膜的菌株ST-01。在50℃下处理6天后，从100 mg样品和10 mg酵母抽提物中提取36 mg细胞，对聚酯进行降解和同化，得到丁二酸、丁酸、戊酸和己酸。该分离物还在50℃下降解了90%以上的聚羟基丁酸酯(PHB)和聚(丁二酸四亚甲酯-己二酸四亚甲酯)薄膜样品。
A thermotolerant Aspergillus sp. strain ST-01 degrading poly(epsilon-caprolactone) films was isolated. The polyester was degraded and assimilated giving 36 mg of cell from 100 mg sample and 10 mg yeast extract after 6 days at 50 degrees C. The degradation products were identified as succinic acid, butyric acid, valeric acid, and caproic acid. The isolate also degraded more than 90% film samples of polyhydroxybutyrate (PHB) and poly(tetramethylene succinate-co-tetramethylene adipate) at 50 degrees C.
