摘　　要： 根据ISO 14855的检测方法,研究了聚丁二酸丁二醇酯(PBS)在堆肥条件下的生物降解性能,结果 表明PBS具有良好的生物降解性,且其形态对其降解速率有显著的影响,降解速率:PBS粉末>PBS片>PBS 颗粒。对堆肥中的微生物进行分离鉴定,在所选堆肥中主要分离出四种菌株:杂色曲霉菌、青霉菌、芽包杆菌 和直杆高温多孢菌,它们对PBS的降解能力各不相同,其中最有效降解PBS的菌株是杂色曲霉菌。 The study on the biodegradation of PBS was carried out under controlled compost conditions according to the method of ISO 14855. The results show that PBS has good biodegradability. Moreover, the biodegradation rate of PBS was affected by the shapes of PBS sample. PBS powders, compared with film and granule, give the largest specific surface area and show the fastest degradation rate. Four strains were separated from the compost and identified to be aspergillus versicolor, penicillium, bacillus and streptomyces. Among them, aspergillus versicolor was the best for the biodegradation of PBS.
