摘要：

To determine the microbial utilization of poly(P-propiolactone) (PPL), the biochemical oxygen demand (BOD) method with sewage sludge and time-course tests with degrading microorganisms isolated from natural environments were conducted. Fibrous PPL with high molecular weight was completely utilized up to CO2 and H2O. Utilization of PPL was achieved not only by a consortium in the sewage sludge but in pure cultures of the degrading microorganisms. It was suggested that PPL-utilizing microorganisms are not necessarily identical with PHB-utilizing microorganisms. An important conclusion is that PPL will be regarded as a utilizable polymeric substrate by the PPL-degrading microorganisms distributed in natural environments. (C) 2000 Elsevier Science Ltd.
