In present study, evaluate the effect of fine coal gasification slag (FCGS) as additive on abundance of bacterial diversity during pig manure composting. The six different dosages of FCGS 0% (T1), 2% (T2), 4% (T3), 6% (T4), 8% (T5) and 10% (T6) (dry weight basis) were mixed with original raw materials for 42 days an aerobic composting. The results indicated that FCGS adopted could affect the succession of bacterial diversity in different ways. Among all treatments, Firmicutes, Proteobacteria, Tenericutes, unidentified_Bacteria, and Actinobacteria were the highest abundance in weighted unifrac distance but Firmicutes; Proteobacteria, Actinobacteria, Bacteroidetes, and Spirochaetes were main bacteria in unweighted unifrac distance. The β-diversity and principal component analysis indicated a significant difference in bacterial diversity in all treatments which T4 obtained difference obviously. Therefore, the results showed that T4 was a potential candidate to enhance significantly abundance of bacterial community in PM compost.
在本研究中，评估了细煤气化渣（FCGS）作为添加剂对猪粪堆肥过程中细菌多样性丰度的影响。将 6 种不同剂量的 FCGS（干重基础）0%（T1）、2%（T2）、4%（T3）、6%（T4）、8%（T5）和 10%（T6）与原始原料混合进行 42 天的好氧堆肥。结果表明，采用的 FCGS 可以以不同的方式影响细菌多样性的演替。在所有处理中，厚壁菌门、变形菌门、无壁菌门、未鉴定的细菌门和放线菌门在加权 unifrac 距离中丰度最高，但在 Firmicutes 中丰度最高；变形菌门、放线菌门、拟杆菌门、螺旋体门是 unweighted unifrac 距离中的主要细菌。β多样性和主成分分析表明，所有处理中的细菌多样性存在显著差异，其中 T4 差异明显。因此，结果表明，T4 是一种有潜力的候选物，可以显著增加 PM 堆肥中细菌群落的丰度。
