Volatile fatty acids (VFAs) produced from organic-rich wastewater by anaerobic digestion attract attention due to the increasing volatile fatty acids market, sustainability and environmentally friendly characteristics. This review aims to give an overview of the roles and applications of enzymes, a biocatalyst which plays a significant role in anaerobic digestion, to enhance volatile fatty acids production. This paper systematically overviewed: (i) the enzymatic pathways of VFAs formation, competition, and consumption; (ii) the applications of enzymes in VFAs production; and (iii) feasible measures to boost the enzymatic processes. Furthermore, this review presents a critical evaluation on the major obstacles and feasible future research directions for the better applications of enzymatic processes to promote VFAs production from wastewater.
挥发性脂肪酸（VFAs）是有机废水在厌氧消化过程中的产物，由于挥发性脂肪酸市场的增长、可持续性和环境友好性等特点，引起了人们的关注。本综述旨在概述在厌氧消化中发挥重要作用的生物催化剂——酶的作用和应用，以提高挥发性脂肪酸的产量。本文系统地综述了：（i）VFAs 的形成、竞争和消耗的酶途径；（ii）酶在 VFAs 生产中的应用；和（iii）提高酶促过程的可行措施。此外，本文还对酶促过程更好地应用于促进废水产 VFAs 的主要障碍和可行的未来研究方向进行了批判性评价。
