This work aims to investigate the influence of hydrogen peroxide (HO) and ascorbic acid (ASCA) on the physicochemical characteristics, organic matter (OM) deconstructions, humification degree and succession of bacterial communities for co-composting of bagasse pith and dairy manure. The results indicated that HO and ASCA accelerated the degradation of lignocellulose, improved the transformation of dissolved organic matter (DOM), and enhanced the content of humic substance (HS) and the degree of its aromatization. The bacterial communities were significantly changed in the presence of additives, in which the relative abundances of Firmicutes and Actinobacteria significantly increased. Redundancy analysis (RDA) indicated that the degradation of OM and lignocellulose more influenced the bacterial community compositions. Conclusively, adding HO and ASCA accelerated lignocellulose degradation efficiency, and improved the composting process, which provided an optimized method to dispose of lignocellulose wastes and livestock manure.
本研究旨在探讨过氧化氢（HO）和抗坏血酸（ASCA）对蔗髓和奶牛粪便共堆肥过程中理化特性、有机质（OM）解构、腐殖化程度和细菌群落演替的影响。结果表明，HO 和 ASCA 加速了木质纤维素的降解，促进了溶解有机物（DOM）的转化，提高了腐殖质（HS）的含量和芳构化程度。添加剂的存在显著改变了细菌群落，其中厚壁菌门和放线菌门的相对丰度显著增加。冗余分析（RDA）表明，OM 和木质纤维素的降解对细菌群落组成的影响更大。总之，添加 HO 和 ASCA 可加速木质纤维素的降解效率，改善堆肥过程，为处理木质纤维素废物和牲畜粪便提供了一种优化方法。
