Polyethylene (PE) has been described as the most abundant plastic worldwide since it is used for the manufacture of disposable recipients, such as bottles and bags. Consequently, large quantities of PE have been accumulating in the environment causing serious ecological problems. Although there are numerous plastic disposal methods, each one has its own inherent limitations, but biodegradation seems to be the least harmful method to deal with this type of contaminant. This mini-review summarizes current advances in PE contamination, focusing on the recent findings related to the biodegradation of PE in different environmental conditions, presenting the microorganisms, genes, and enzymes involved, as well as the mechanisms of PE biodegradation. It also attempts to address the main and current biodegradation methods used to minimize the impacts of this polymer on the environment.
聚乙烯（PE）被描述为全球最丰富的塑料，因为它用于制造一次性容器，如瓶子和袋子。因此，大量的 PE 已经在环境中积累，造成了严重的生态问题。尽管有许多塑料处理方法，但每种方法都有其自身的固有局限性，但生物降解似乎是处理这种污染物的最无害的方法。本迷你综述总结了目前关于 PE 污染的进展，重点介绍了最近在不同环境条件下关于 PE 生物降解的发现，介绍了参与的微生物、基因和酶，以及 PE 生物降解的机制。它还试图解决目前用于最小化这种聚合物对环境影响的主要生物降解方法。
