Abstract

Purpose of Review

The exponentially increasing plastic pollution in environment requires effective and sustainable biodegradation methods. Superworm (larvae of Zophobas atratus also known as Zophobas morio) have been shown to ingest and degrade plastics/microplastics depending on environmental conditions. Because there is no sufficient knowledge of the effect of plastics/microplastics on superworms and analysis of their degradation mechanism, it is timely to provide more evidences to demonstrate their capability, impact, degradation pathways, and remaining challenges. Therefore, this review aims to comprehensively discuss the ability of superworms to degrade plastics or microplastics (MPs).

Recent Findings

Superworms have demonstrated the ability to metabolize various types of plastics or MPs into carbon dioxide and larval biomass. The degradation process involves depolymerization and subsequent microbial action within their gut, leading to a reduction in the size and chemical complexity of the plastics. Microbes such as Pseudomonas sp., Enterobacteriaceae sp., and Enterococcus sp. have been commonly observed in the gut of superworms.

Summary

This review showed that most previous works focus on the use of superworms to degrade/remove PS, whereas other types of plastic polymers, such as polyethylene terephthalate (PET), have not been explored. Implementation of this technology has the potential to significantly reduce plastic pollution and support environmental sustainability solutions.

利用超级蠕虫对塑料/微塑料进行生物降解的生物创新解决方案微型综述

综述目的环境中的塑料污染呈指数级增长，需要有效和可持续的生物降解方法。有研究表明，超级蠕虫（Zophobas atratus 幼虫，又称 Zophobas morio）可根据环境条件摄取并降解塑料/微塑料。由于对塑料/微塑料对超级蠕虫的影响及其降解机制的分析还缺乏足够的了解，因此提供更多证据来证明超级蠕虫的能力、影响、降解途径和仍然存在的挑战是非常及时的。因此，本综述旨在全面讨论超级蠕虫降解塑料或微塑料（MPs）的能力。降解过程包括解聚和随后在其肠道内的微生物作用，从而减小塑料的尺寸和化学复杂性。在超级蠕虫的肠道中通常可以观察到假单胞菌属、肠杆菌属和肠球菌属等微生物。摘要本综述表明，以前的大多数研究工作都集中在利用超级蠕虫降解/去除聚苯乙烯上，而其他类型的塑料聚合物，如聚对苯二甲酸乙二醇酯（PET），还没有被探索过。这项技术的实施有可能大大减少塑料污染，支持环境可持续发展解决方案。
