Anaerobic co-digestion generally results in a higher yield of biogas than mono-digestion, hence co-digestion has become a topic of general interest in recent studies of anaerobic digestion. Compared with mono-digestion, co-digestion utilizes multiple substrates. The balance of substrate nutrient in co-digestion comprises better adjustments of C/N ratio, pH, moisture, trace elements, and dilution of toxic substances. All of these changes could result in positive shifts in microbial community structure and function in the digestion processes and consequent augmentation of biogas production. Nevertheless, there have been few reviews on the interaction of nutrient and microbial community in co-digestions. The objective of this review is to investigate recent achievements and perspectives on the interaction of substrate nutrient balance and microbial community structure and function. This may provide valuable information on the optimization of combinations of substrates and prediction of bioreactor performance.
厌氧共消化通常比单消化产生更高的沼气产量，因此共消化已成为最近厌氧消化研究中普遍关注的话题。与单消化相比，共消化利用多种底物。共消化中底物营养的平衡包括更好地调整 C/N 比、pH 值、水分、微量元素和稀释有毒物质。所有这些变化都可能导致消化过程中微生物群落结构和功能的积极转变，并因此增加沼气产量。然而，关于共消化中营养物质和微生物群落相互作用的综述很少。本综述的目的是研究底物营养平衡和微生物群落结构和功能相互作用的最新进展和观点。这可能为优化底物组合和预测生物反应器性能提供有价值的信息。
