生物可降解聚合物有许多可能的应用，包括外科植入物，缝合线，覆盖物和控释药物，杀虫剂，杀虫剂和肥料。已经报道了许多可生物降解的聚合物，并且已经检查了一些能够降解它们的生物体和酶（1-3）。这里报道的工作通过扫描电子显微镜（SEM）可视化了生物降解过程中涉及的物理变化。所使用的系统由在几种丝状真菌存在下的聚己内酯700（PCL 700）或聚己内酯300（PCL 300）的膜组成。选择PCL进行研究，因为据报道它是可生物降解的（3），并且它是市售的。丝状真菌被广泛认为是天然聚合物生物降解的主要原因，并且已经报道了它们降解PCL的能力（4-6）。
There are many possible applications of biodegradable polymers, including surgical implants, sutures, mulches, and controlled-release drugs, pesticides, insecticides, and fertilizers. A number of biodegradable polymers have been reported and some organisms and enzymes capable of degrading them have been examined (1-3).The work reported here visualizes by scanning electron microscopy (SEM) the physical changes involved in the biodegradation process. The system used consists of films of polycaprolactone 700 (PCL700) or polycaprolactone 300 (PCL300) in the presence of several filamentous fungi. PCL was chosen for investigation because it has been reported to be biodegradable (3) and it is commercially available. The filamentous fungi are widely recognized as being a major cause of biodeterioration of natural polymers and their ability to degrade PCL has been reported (4-6).
