Abstract

Per- and polyfluoroalkyl substances (PFAS) are a group of chemicals widely manufactured for industrial and commercial applications in the past decades due to their remarkable stability as well as hydrophobic and lipophobic nature. PFAS species have been recognized as emerging environmental contaminants of concern due to their toxicity and environmental persistence, thereby attracting intensive research seeking effective technologies for their removal from the environment. The objective of this review is to provide a thorough analysis of the biodegradation of PFAS in multiple environmental matrices and offer a future outlook. By discussing targeted PFAS species, degradation intermediates, degradation efficiencies, and microbial species, a comprehensive summary of the known microbial species and their degradation pathways are presented. The biodegradation pathways for different types of PFAS species are summarized in two major categories, biodegradation with and without the cleavage of C-F bond. Existing uncertainties and future research directions for PFAS biodegradation are provided.

全氟和多氟烷基物质(PFAS)的生物降解研究进展

全氟烷基和多氟烷基物质(PFAS)由于其卓越的稳定性以及疏水性和疏脂性，在过去几十年中广泛用于工业和商业应用的一组化学品。由于其毒性和环境持久性，PFAS物种已被认为是令人关注的新兴环境污染物，因此吸引了大量研究，寻求将其从环境中去除的有效技术。本文综述了PFAS在多种环境基质中的生物降解研究进展，并对其发展前景进行了展望。通过对PFAS靶菌种类、降解中间体、降解效率和微生物种类的讨论，对已知的PFAS靶菌种类及其降解途径进行了综述。将不同类型PFAS的生物降解途径归纳为两大类:劈裂C-F键和不劈裂C-F键的生物降解。指出了PFAS生物降解存在的不确定因素和未来的研究方向。

期刊介绍： Bioresource Technology publishes original articles, review articles, case studies, and short communications covering the fundamentals, applications, and management of bioresource technology. The journal seeks to advance and disseminate knowledge across various areas related to biomass, biological waste treatment, bioenergy, biotransformations, bioresource systems analysis, and associated conversion or production technologies. Topics include: • Biofuels: liquid and gaseous biofuels production, modeling and economics • Bioprocesses and bioproducts: biocatalysis and fermentations • Biomass and feedstocks utilization: bioconversion of agro-industrial residues • Environmental protection: biological waste treatment • Thermochemical conversion of biomass: combustion, pyrolysis, gasification, catalysis.
