By applying the plate count and clear-zone methods, it was confirmed that polylactide (PLA)-degrading microorganisms are sparsely distributed in soil environments. An Amycolatopsis isolate was successfully isolated. Microbial degradation of PLA film was demonstrated; i.e., about 60% of the 100-mg film initially added was degraded by the strain after 14 days of liquid culture.
通过平板计数和抑菌圈方法证实，聚乳酸（PLA）降解微生物在土壤环境中分布稀疏。成功分离到一株阿霉素链霉菌（Amycolatopsis）。证明了 PLA 薄膜的微生物降解；即在液体培养 14 天后，该菌株可降解初始添加的 100mg 薄膜的约 60%。
