摘要

双酚A (BPA)被认为是一种内分泌干扰物,能够通过模仿雌激素的作用来干扰体内激素的正常功能。饮用水是BPA最常见的接触途径之一,因为它可以渗透到塑料制品和其他材料中,进入水源。本文综述了双酚a的产生、来源、环境命运、对人类健康的影响以及真菌在双酚a生物降解中的作用。真菌是天然的分解者,能够在适当的条件下分解有机化合物,包括双酚a。研究表明,特定种类的真菌可以有效地生物降解BPA。一些真菌利用木质素分解酶,如漆酶和过氧化物酶,来分解BPA的酚环。其他真菌利用非木质素分解酶,如酯酶和水解酶,来切割双酚a中的酯键。此外,一些真菌可以通过代谢途径分解BPA,这种化学物质作为另一种底物降解的副反应而降解。固定化酶用于双酚a降解也显示出潜力。固定化酶是指那些附着在固体载体上的酶,如聚合物或基质,使它们能够多次使用,并提高它们的稳定性和催化活性

Role of Fungi in Biodegradation of Bisphenol A: A Review
Bisphenol A (BPA) is recognized as an endocrine disruptor, capable of interfering with the normal functioning of hormones within the body by mimicking the effects of estrogen. Drinking water is one of the most common pathways of exposure to BPA as it can permeate plastic products and other materials, entering water sources. This article presents a comprehensive overview of BPA, including its incidence, origins, environmental fate, its impact on human health, and the role of fungi in the biodegradation of BPA. Fungi are natural decomposers, capable of breaking down organic compounds, including BPA, under suitable conditions. Studies have demonstrated that specific species of fungi can effectively biodegrade BPA. Some fungi utilize ligninolytic enzymes, such as laccases and peroxidases, to break down the phenolic rings of BPA. Other fungi employ non-ligninolytic enzymes, such as esterases and hydrolases, to cleave the ester linkages in BPA. Furthermore, some fungi can break down BPA via cometabolic pathways, whereby the chemical is degraded as a side reaction to the degradation of another substrate. The use of immobilized enzymes for BPA degradation has also demonstrated potential. Immobilized enzymes are those that are attached to a solid support, such as a polymer or matrix, allowing them to be used multiple times and enhance their stability and catalytic activity
