河流水体与滨岸土壤微生物群落特征差异分析
Comparison of microbial community characteristics in river water, sediment and riparian soil
摘要
Abstract
A comparison of differences of total bacteria,ammonia oxidizing archaea (AOA) and ammonia oxidizing bacteria (AOB) communities between water,sediment and riparian soil sampled in Weihe River catchment is made based on the terminal restriction fragment length polymorphism (T-RFLP) technique.The species abundance and Shannon index of microbial communities in soil are higher than the result of water and sediment.Soil and water share more T-RFs and have higher similarity in community structure than sediment and water.Either AOA or AOB community similarity between different samples is higher than that of total bacterial communities.Compositions of dominant bacterial species in water,sediment and soil are quite different,while both AOA and AOB dominant species in different samples are relatively more similar.The results show that riparian soil seems a major source of microorganism in Weihe River,with positive effect on the stability of AOA or AOB communities and the diversity of total bacteria in the river.关键词
