一株新的聚乳酸（PLA）降解放线菌Kibdelosporangium aridum在液体培养中14 d内可降解100 mg高分子量聚乳酸膜（Mn：3.4 × 10（5））中的97 mg以上。乳酸是聚乳酸单体降解产物，被该菌完全同化。在固体培养中，通过扫描电子显微镜观察到许多由丝状微生物在PLA膜表面的形态形成的明显凹槽。
A new poly(L-lactide) (PLA)-degrading actinomycete, Kibdelosporangium aridum, degraded more than 97 mg out of 100 mg added high molecular weight PLA film (Mn: 3.4 x 10(5)) within 14 d in liquid culture. L-Lactic acid, the monomeric degradation product of PLA, was totally assimilated by the strain. In solid culture, many distinct grooves formed by the morphology of filamentous microorganisms on the surface of a PLA film were observed by scanning electron microscopy.
