主要方法:

使用各种老年国会议员进行照片转换实验.
关于MPs和反应性氧物种 (ROS) 生产的特征.
灭和探测实验.
理论计算,TOC,以及GC-MS分析.

主要成果:

聚烯MPs (PSMPs) 促进了LSTP的光转换,随着年龄的增长而增加.
聚乙烯二甲 MPs (PETMPs) 的效果较弱,而聚乳酸MPs (PLAMPs) 的效果较弱,因衰老而减弱.

Microbial Bioremediation of Plastics

Polyethylene terephthalate (PET) is a synthetic polymer widely utilized in the packaging industry, particularly for bottles and containers. Due to its chemical stability and durability, PET accumulates in the environment, contributing significantly to plastic pollution. It comprises repeating units of terephthalic acid and ethylene glycol, resulting in a semi-crystalline structure that is resistant to natural degradation processes.A notable breakthrough in plastic biodegradation came with the...
