Organics metabolic function of bacterial communities was evaluated in 60 days composting of swine manure and pumice by using MiSeq sequencing, PICRUSt and Biolog tools. The diversity of bacterial communities significantly decreased during the first 10 days, and gradually increased in the cooling and curing phase. The PICRUSt and Biolog analysis indicated that carbohydrate, lipid and amino acids metabolisms were relatively higher in the thermophilic phases. Xenobiotics biodegradation and metabolism, lipid metabolism, terpenoids and polyketides and biosynthesis of other secondary metabolites were mainly detected in the curing phases. Canonical correspondence analysis (CCA) indicated that the succession of bacterial community and organics utilization characteristics were highly affected by the temperature, moisture and oxidation reduction potential (ORP) in the swine composting system.

通过使用MiSeq测序，PICRUSt和Biolog工具在猪粪和浮石堆肥60天中评估了细菌群落的有机物代谢功能。在最初的10天中，细菌群落的多样性显着下降，在冷却和固化阶段逐渐增加。PICRUSt和Biolog分析表明，在嗜热阶段，碳水化合物，脂质和氨基酸的代谢相对较高。主要在固化阶段检测到异种生物的生物降解和代谢，脂质代谢，萜类化合物和聚酮化合物以及其他次生代谢产物的生物合成。典范对应分析（CCA）表明，细菌群落的演替和有机物的利用特性受温度的影响很大，
