Outline of Final Research Achievements	The anaerobic biodegradability of four bioplastics, polycaprolactone (PCL), poly(lactic acid) (PLA), polyhydroxybutyrate (PHB) and poly(butylene succinate) (PBS), were compared at 37°C and 55°C. The microorganisms participating in anaerobic bioplastic biodegradation were detected using the RT-PCR DGGE method. The anaerobic biodegradability of different molecular weight PLA films were compared.
