Oil palm processing generates substantial waste materials rich in organic content, posing various environmental challenges. Anaerobic digestion (AD), particularly for palm oil mill effluent (POME), offers a sustainable solution, by converting waste into valuable biomethane for thermal energy or electricity generation. The synergistic activities of the AD microbiota directly affect the biomethane production, and the microbial community involved in biomethane production in POME anaerobic digestion has been reported. The composition of bacterial and archaeal communities varies under different substrate and physicochemical conditions. This review discusses the characteristics of POME, explores the microbial members engaged in each stage of AD, and elucidates the impacts of substrate and physicochemical conditions on the microbial community dynamics, with a specific focus on POME. Finally, the review outlines current research needs and provides future perspectives on optimizing the microbial communities for enhanced biomethane production from oil palm wastes.
油棕加工产生大量富含有机成分的废料，带来了各种环境挑战。厌氧消化（AD），特别是针对棕榈油厂废水（POME）的厌氧消化，通过将废物转化为用于热能或发电的宝贵生物甲烷，提供了一种可持续的解决方案。AD微生物群的协同活动直接影响生物甲烷的产生，并且已经报道了参与POME厌氧消化中生物甲烷产生的微生物群落。细菌和古菌群落的组成在不同的底物和理化条件下会有所不同。本综述讨论了POME的特性，探索了参与AD各个阶段的微生物成员，并阐明了底物和理化条件对微生物群落动态的影响，特别关注POME。最后，该综述概述了当前的研究需求，并提供了关于优化微生物群落以提高油棕废料生物甲烷产量的未来展望。
