Abstract

Since the invention of the first synthetic plastic, an estimated 12 billion metric tons of plastics have been manufactured, 70% of which was produced in the last 20 years. Plastic waste is placing new selective pressures on humans and the organisms we depend on, yet it also places new pressures on microorganisms as they compete to exploit this new and growing source of carbon. The limited efficacy of traditional recycling methods on plastic waste, which can leach into the environment at low purity and concentration, indicates the utility of this evolving metabolic activity. This review will categorize and discuss the probable metabolic routes for each industrially-relevant plastic, rank the most effective biodegraders for each plastic by harmonizing and re-interpreting prior literature, and explain the experimental techniques most often used in plastic biodegradation research, thus providing a comprehensive resource for researchers investigating and engineering plastic biodegradation.

塑料生物降解的生化机制。
自第一种合成塑料发明以来,估计已生产了 120 亿吨塑料,其中 70% 是在过去 20 年中生产的。塑料垃圾给人类和我们赖以生存的生物带来了新的选择性压力,同时也给微生物带来了新的压力,因为它们要竞相利用这种新的、不断增长的碳源。塑料废物的纯度和浓度都很低,传统回收方法对塑料废物的效果有限,这表明这种不断发展的新陈代谢活动非常有用。本综述将对每种与工业相关的塑料的可能代谢途径进行分类和讨论,通过协调和重新解释以前的文献,对每种塑料最有效的生物降解剂进行排名,并解释塑料生物降解研究中最常用的实验技术,从而为研究塑料生物降解和工程的研究人员提供全面的资源。
