Anaerobic digestion (AD) is frequently restricted with the long lag phase and low methane (CH₄) production rate. Laboratory batch experiments were conducted to investigate the impact of different supplements on the performance of food waste AD, including AC-Ni, AC, and Ni. Results showed that the lag phase of AD was reduced with the addition of those supplementations. Compared with the control group without any supplementation, the AC-Ni could shorten the lag phase by 67% and increase the maximum CH₄ production rate by 50%, respectively. The speciation analysis indicated that the environmental risks of the AC-Ni was reduced by 30% after digestion. Microbial community structure analysis revealed that the AC-Ni promoted the evolution and activity of the hydrolytic-fermentative bacteria (e.g. Firmicutes and Bacteroidetes) and methanogens (e.g. Methanobacterium, Methanoregula and Methanomassiliicoccus). This study suggested that the AC-Ni waste could be feasible to be applied to enhance the performance of AD.

厌氧消化（AD）经常受到滞后期长和甲烷（CH ₄）生产率低的限制。进行了实验室分批实验，以研究各种补品对食物垃圾AD（包括AC-Ni，AC和Ni）的性能的影响。结果表明，添加这些补充剂可以减少AD的滞后期。与不加任何补充剂的对照组相比，AC-Ni可使滞后期缩短67％，并增加最大CH ₄生产率分别提高了50％。形态分析表明，消解后AC-Ni的环境风险降低了30％。微生物群落结构分析表明，AC镍促进水解发酵菌的演变和活动（如厚壁菌门和拟杆菌）和产甲烷菌（如甲烷，Methanoregula和Methanomassiliicoccus）。这项研究表明，AC-Ni废料可用于提高AD的性能。
