Thermophilic actinomycetes strains were isolated from various environment in Taiwan and screened for degradation of poly(ethylene succinate) (PES), poly(epsilon-caprolactone) (PCL) and/or poly(beta-hydroxybutyrate) (PHB) by the clear-zone method. Out of 341 strains of thermophilic actinomycetes, 105 isolates were PHB-degraders (30.8%), 198 isolates were PCL-decomposers (58.1%), and 99 isolates could degrade PES (29.0%). Furthermore, 77 isolates could degrade both PHB and PCL (22.6%), 35 isolates could degrade both PHB and PES (10.3%), 81 isolates could degrade both PES and PCL (23.8%) and 31 isolates could degrade the three polyesters used in this study (9.1%). Base on the morphological and chemical characteristics, these 31 isolates belonging to Actinomadura (12.9%), Microbispora (25.8%), Streptomyces (48.4%), Thermoactinomyces (9.7%) and Saccharomonospora genus (3.22%).
从台湾的各种环境中分离出嗜热放线菌菌株，并通过透明圈法筛选其对聚琥珀酸乙二酯（PES）、聚己内酯（PCL）和/或聚（β-羟基丁酸酯）（PHB）的降解能力。在341株嗜热放线菌中，105株为PHB降解菌（30.8%），198株为PCL分解菌（58.1%），99株可降解PES（29.0%）。此外，77株可同时降解PHB和PCL（22.6%），35株可同时降解PHB和PES（10.3%），81株可同时降解PES和PCL（23.8%），31株可降解本研究中使用的三种聚酯（9.1%）。根据形态和化学特征，这31株菌株分别属于马杜拉放线菌属（12.9%）、小双孢菌属（25.8%）、链霉菌属（48.4%）、嗜热放线菌属（9.7%）和糖单孢菌属（3.22%）。
