摘要

       厌氧消化是一项历史悠久的技术，用于对各种有机废物进行增值，同时产生有价值的资源。然而，单一消化（即使用一种原料进行厌氧消化）受到与原料特性相关的挑战。使用多种原料的共消化提供了克服这些限制的潜力。大量的研究和开发工作突出了共同消化的几个固有优点，包括由于共同底物的协同作用而提高的消化率、更好的过程稳定性和产生的共同消化物的更高营养价值。然而，迄今为止，还没有综合研究集中在不同共同原料对消化器性能和稳定性的潜在影响。本综述通过强调单一消化的局限性并批判性地研究共同消化的好处来填补这一空白。此外，本综述讨论了共底物的协同效应、微生物群落的表征、通过不同动力学模型预测沼气产量，并强调了可持续生物精炼厂发展的未来研究方向。

       Anaerobic digestion is a long-established technology for the valorization of diverse organic wastes with concomitant generation of valuable resources. However, mono-digestion (i.e., anaerobic digestion using one feedstock) suffers from challenges associated with feedstock characteristics. Co-digestion using multiple feedstocks provides the potential to overcome these limitations. Significant research and development efforts have highlighted several inherent merits of co-digestion, including enhanced digestibility due to synergistic effects of co-substrates, better process stability, and higher nutrient value of the produced co-digestate. However, studies focused on the underlying effects of diverse co-feedstocks on digester performance and stability have not been synthesized so far. This review fills this gap by highlighting the limitations of mono-digestion and critically examining the benefits of co-digestion. Furthermore, this review discusses synergistic effect of co-substrates, characterization of microbial communities, the prediction of biogas production via different kinetic models, and highlights future research directions for the development of a sustainable biorefinery.
