摘要:

综述了近期聚乙烯(PE)微生物降解的研究进展,主要包括参与生物降解的微生物和实验表征方法,从中发现在降解能力测试中由于所用PE类型的不同和表征方法的误用等因素,造成无法对各类型降解菌的降解效率进行对比,最后,提出了对PE微生物降解的实验流程的改进建议和补充,为进一步研究PE的微生物降解特别是降解菌的高效性定义提供参考。

关键词: 聚乙烯, 微生物, 降解, 表征方法

Abstract:

This paper reviewed the recent research progress in the microbial degradation of polyethylene (PE), which mainly included the microorganisms involved in biodegradation and the characterization methods used in the experiment. Many studies indicated that it was impossible to compare the degradation efficiency of various types of degrading bacteria due to the different types of PE used and the misuse of characterization methods. Finally, the paper proposed the methodologies for the improvement and supplement of the experimental process of PE biodegradation, which provided a reference for the further study of polyethylene biodegradation, especially for the definition of high efficiency of degrading bacteria.

Key words: polyethylene, microbe, degradation, characterization method
