Variations in rhizosphere microbial community structure of bulrush in Wusong estuarine wetland, Shanghai

摘要

In this work, variations in rhizosphere microbial community in Wusong estuarine wetland were studied under simulated conditions through phospholipid fatty acids (PLFAs) analysis. Native plant species, bulrush (Scirpus tripueter) was tested in the study. The results indicated the root effect caused a shift in the microbial community structure to more fungi, more GP bacteria and more aerobic bacteria. Total PLFAs to change with seasons with the greater biomass size occurring in summer, and the total PLFAs decreased in later summer. Season is the dominant factor influencing the size of soil microbial biomass and biomass is higher in early summer and early winter. The results illustrated that bulrush and the rhizosphere microorganisms could be appropriately matched to cure and restore the ecological environment similar to Wusong estuary wetland contaminated by petroleum pollutants.
