Abstract:
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.
