Abstract

Over the recent decades, global plastic production has grown dramatically due to the huge demands of consumption. As a consequence, large amounts of plastic waste have accumulated in the environment and will be cleaved into microplastics. Due to the low bioavailability, the microplastics will exist in the environment persistently and cause massive environmental stress. Plastic pollution is currently one of the biggest environmental concerns. Recent studies have shown the possibility to obtain degrading microorganisms of microplastics from the natural environment. Some microorganisms can break down microplastics into water and carbon dioxide. This paper reviewed the current research on biodegradation of polyethylene (PE), which is the most abundant microplastic type in the environment, and discussed the quantification methods of the degradation effect. Given that current biodegradation efficiency is relatively limited, further research is required.

聚乙烯微塑料生物降解研究进展[j]。
近几十年来,由于巨大的消费需求,全球塑料产量急剧增长。因此,大量的塑料垃圾在环境中积累,并将被分解成微塑料。微塑料由于生物利用度低,会长期存在于环境中,造成巨大的环境压力。塑料污染是目前最大的环境问题之一。最近的研究表明,从自然环境中获得降解微塑料的微生物是可能的。一些微生物可以将微塑料分解成水和二氧化碳。本文综述了环境中最丰富的微塑料类型聚乙烯(PE)的生物降解研究现状,并对其降解效果的量化方法进行了探讨。鉴于目前生物降解效率相对有限,需要进一步研究。
