Random aliphatic-aromatic copolyesters synthesized from 1,4-butanediol, adipic acid, and terephthalic acid (BTA) have excellent thermal and mechanical properties and are biodegradable by mixed cultures (e.g., in compost). Over 20 BTA-degrading strains were isolated by using compost as a microbial source. Among these microorganisms, thermophilic actinomycetes obviously play an outstanding role and appear to dominate the initial degradation step. Two actinomycete strains exhibited about 20-fold higher BTA degradation rates than usually observed in a common compost test. These isolates were identified as Thermomonospora fusca strains. They appeared to be particularly suitable for establishment of rapid degradation tests and were used in comparative studies on the biodegradation of various polyesters.
由1,4-丁二醇、己二酸和对苯二甲酸（BTA）合成的无规脂肪族-芳香族共聚酯具有优异的热性能和机械性能，并且可被混合培养物（如在堆肥中）生物降解。通过将堆肥作为微生物源，分离出了20多种降解BTA的菌株。在这些微生物中，嗜热放线菌显然发挥着突出作用，并且似乎主导着初始降解步骤。两种放线菌菌株的BTA降解率比普通堆肥试验中通常观察到的高出约20倍。这些分离物被鉴定为栖热单孢菌菌株。它们似乎特别适合用于建立快速降解试验，并被用于各种聚酯生物降解的比较研究。
