Influence of biodegradation in thermophilic anaerobic aqueous conditions on crystallization of poly(butylene succinate)

Original language description

This work investigates the biodegradation of poly(butylene succinate) (PBS) in an environment of thermophilic (55oC) and mesophilic (37oC) anaerobic sludge. The thermophilic anaerobic sludge was prepared in a laboratory from mesophilic sludge sourced from a municipal waste water treatment plant and placed under thermophilic conditions. It was confirmed that PBS failed to decompose under mesophilic anaerobic conditions (2 wt. %), while the degree of biodegradation achieved under thermophilic conditions reached 24.8 wt. %. Abiotic hydrolysis of PBS in an environment of phosphate buffer (pH = 7) at 55oC reached 17.8%, leading to the conclusion that hydrolytic enzymes present in thermophilic anaerobic sludge are involved in the biodegradation process as well as abiotic hydrolysis. Nonisothermal crystallization kinetics of PBS before and after biodegradation was investigated by differential scanning calorimetry (DSC). After biodegradation, a large shift in melting temperature T<inf>m</inf>
