Abstract

Environmental concerns about the widespread use of non-biodegradable plastic have generated interest in developing quick and effective methods to degrade synthetic polymers. With millions of tons of plastic waste generated annually, biodegradation by microorganisms presents a promising and eco-friendly solution. However, a bottleneck has arisen due to the lack of standardized methods for verification of the biodegradation process. Based on this literature review, he techniques most commonly employed for this purpose currently include measuring mass loss, examining the surface of plastic fragments by scanning electron microscopy (SEM) and atomic force microscopy (AFM), and using analytical methods such as Fourier transform infrared spectroscopy (FTIR), pyrolysis-gas chromatography-mass spectrometry (Pyr-GC/MS) or high-performance liquid chromatography (HPLC). Each of these methods has its advantages and disadvantages. Nevertheless, currently, there is no universal approach to accurately assess the ability of individual microorganisms to degrade plastics. In this review, we summarize the latest advances in techniques for detecting biodegradation of synthetic polymers and future directions in the development of sustainable strategies for mitigating plastic pollution.

微塑料检测和塑料生物降解的最新方法。

对不可生物降解塑料的广泛使用的环境问题引起了人们对开发快速有效的方法来降解合成聚合物的兴趣。由于每年产生数百万吨塑料废物，微生物的生物降解提供了一个有前途的环保解决方案。然而，由于缺乏验证生物降解过程的标准化方法，出现了瓶颈。基于这一文献综述，目前最常用的技术包括测量质量损失，通过扫描电子显微镜（SEM）和原子力显微镜（AFM）检查塑料碎片表面，以及使用傅立叶变换红外光谱（FTIR），热解-气相色谱-质谱法（Pyr-GC/MS）或高效液相色谱法（HPLC）等分析方法。每种方法都有其优点和缺点。然而，目前还没有通用的方法来准确评估单个微生物降解塑料的能力。本文综述了合成聚合物生物降解检测技术的最新进展，并展望了塑料污染可持续发展策略的发展方向。

期刊介绍： Molecules (ISSN 1420-3049, CODEN: MOLEFW) is an open access journal of synthetic organic chemistry and natural product chemistry. All articles are peer-reviewed and published continously upon acceptance. Molecules is published by MDPI, Basel, Switzerland. Our aim is to encourage chemists to publish as much as possible their experimental detail, particularly synthetic procedures and characterization information. There is no restriction on the length of the experimental section. In addition, availability of compound samples is published and considered as important information. Authors are encouraged to register or deposit their chemical samples through the non-profit international organization Molecular Diversity Preservation International (MDPI). Molecules has been launched in 1996 to preserve and exploit molecular diversity of both, chemical information and chemical substances.
