This study investigated the effects of biochar-based solid acids (SAs) on carbon conversion, alpha diversity and bacterial community succession during cow manure composting with the goal of providing a new strategy for rapid carbon conversion during composting. The addition of SA prolonged the thermophilic phase and accelerated the degradation of lignocellulose; in particular, the degradation time of cellulose was shortened by 50% and the humus content was increased by 22.56% compared with the control group (CK). In addition, high-throughput sequencing results showed that SA improved the alpha diversity and the relative abundance of thermophilic bacteria, mainly Actinobacteria, increased by 12.955% compared with CK. A redundancy analysis (RDA) showed that Actinobacteria was positively correlated with the transformation of carbon.
本研究探讨了生物炭基固体酸（SAs）对牛粪堆肥过程中碳转化、α多样性和细菌群落演替的影响，旨在为堆肥过程中快速碳转化提供新策略。添加 SAs 延长了高温期并加速了木质纤维素的降解；特别是，与对照组（CK）相比，纤维素的降解时间缩短了 50%，腐殖质含量增加了 22.56%。此外，高通量测序结果表明，SAs 提高了α多样性和嗜热细菌的相对丰度，与 CK 相比，放线菌增加了 12.955%。冗余分析（RDA）表明，放线菌与碳的转化呈正相关。
