Abstract:
The distribution of ammonia-oxidizing archaea (AOA) and bacteria (AOB) in cattle, swine, and chicken manure compost was analyzed. PCR-denaturing gradient gel electrophoresis (DGGE) showed that a Candidatus Nitrososphaera gargensis-like sequence dominated in cattle manure compost, while few AOA were detected in other composts. In the case of AOB, Nitrosomonas-like sequences were detected with higher diversity in cattle and swine manure composts. The relative abundance of ammonia oxidizers by real-time PCR revealed that more AOB was present in compost except in one swine manure compost. Our results indicated that AOB rather than AOA are widely distributed in animal manure compost.
