The performance of poly butylene sucinate-co-adipate (PBSA) degrading bacteria inoculation in compost

Abstract

 This paper presents the degradation ability of selected strains on poly butylene succinate-co-adipate (PBSA) in culture medium and compost. Thirty four strains of PBSA degrading bacteria were isolated from compost and activated sludge, and six of them were used as inocula for the experiments to investigate PBSA degradation ability in compost. The results revealed that bacteria inoculation could accelerate the PBSA degradation. Two strains (Acinetobacter sp. Strain.S49 and Acinetobacter sp. Strain.S6) showed high ability of degrading PBSA in compost, whereas the other four strains showed minor effects. Based on the findings in this work, the importance to investigate the ability of PBSA degrading bacteria not only using pure culture medium but also using multi-microbial community such as compost was indicated.
