In vitro biodegradation of polyester-based plastic materials by selected bacterial cultures

摘要

A simple and rapid in vitro test was designed for the assessment of the biodegradation of polyester- based plastics by selected biodegrading bacterial strains. Variovorax paradoxus LMG 16137 was used for the degradation of poly(3-hydroxybutyrate-co-3-hydroxyvalerate)and Acidovorax ave- nae subsp. avenae LMG 17238 for the synthetic-based polyesters poly(ε-caprolactone)(PCL), poly(butylene succinate-co-butylene adipate), and starch-PCL blend.
