Degradation of syndiotactic poly([R]-b-hydroxybutyrate) (syn-PHB), a chemically synthesized PHB, was investigated in this study by incubation polymer films in a soil of northeastern China. During incubation, progressive weight loss of the syn-PHB films and a corresponding decrease of molecular weight were observed over the 90 days of incubation indicating the biodegradation of syn-PHB and the random cleavage of ester bonds. Microorganisms isolated and identified from the partially degraded
