摘要：

The influence of biochar derived from a hardwood tree (Quercus serrate Murray) on the dynamics of the microbial community during the composting of poultry manure (PM) and cow manure (CM) was evaluated by phospholipid fatty add analysis (PLFAs). Changes in the PLFA patterns were related to key composting properties (C/N ratio, temperature, and bulk density) as the major drivers of the dynamics of the microbial community. At the beginning of the process, the fungal biomass was significantly greater in PM and CM than in the respective co-composted materials with biochar (PMB and CMB): this difference declined gradually during the process. In contrast, the Gram+ to Gram - ratio was increased by the presence of biochar. After 12 weeks of composting, factor analysis based on the relative abundances of single PLFAs revealed changes in the microbial community structure which depended on the original organic wastes (CM vs PM).
