| 摘 要： | 研究了聚丁二酸丁二醇酯(PBS)及其共聚物聚丁二酸/己二酸-丁二醇酯(PBSA)薄膜在可控堆肥条件下的宏观生物降解行为,结果显示,PBS和PBSA薄膜具有良好的生物降解性能,降解过程经历三个阶段:诱导期、加速期和平坦期。对堆肥中的微生物进行分离和筛选,发现杂色曲霉菌对PBS和PBSA的生物降解能力最强。进一步研究PBS和PBSA薄膜在杂色曲霉菌作用下的微观生物降解行为,结果表明,PBSA薄膜比PBS薄膜具有更快的生物降解速率。

| Abstract: | The biodegradation behavior of poly(butylene succinate)(PBS) and poly(butylene succinate-co-butylene adipate)(PBSA) films was studied under controlled composting conditions.The ultimate biodegradation percentage revealed that PBS and PBSA films show good biodegradability.The biodegradation process of PBS and PBSA films under controlled composting conditions exhibited three phases.The biodegradation in the first phase was slow,got accelerated in the second phase and showed a leveling-off in the third phase.Aspergillus versicolor was isolated from the compost and confirmed to be the best degrading microorganism for PBS and PBSA in the compost.The biodegradation behavior of PBS and PBSA films by Aspergillus versicolor was further studied.PBSA film exhibited a faster degradation than PBS film. |
