nitrification process in lake ecosystems. However, the relative effects of climate, catchment
land use and local conditions on the sediment ammonia-oxidizing communities in lakes
remain unclear. In this study, the diversity and abundance of AOA and AOB communities
were investigated in ten Yangtze lakes by polymerase chain reaction (PCR), clone library
and quantitative PCR techniques. The results showed that the abundances of both AOA and …
