Short-term effects of diesel fuel on rhizosphere microbial community structure of native plants in Yangtze estuarine wetland.

Purpose: In this work, short-term effects of diesel fuel on Huangpu-Yangtze estuarine wetland soil microbial community structure were studied under simulated conditions through phospholipid fatty acids (PLFAs) analysis. Four native plant species, bulrush (Scirpus tripueter), galingale (Cyperus rotundus), wildrice (Zizania latifolia), and reed (Phragmites australis) were tested in the experiments.

Method: In the pot experiment, 20 g rhizosphere soils were mixed with 20 g diesel-blended soils.

Responses of Scirpus triqueter, soil enzymes and microbial community during phytoremediation of pyrene contaminated soil in simulated wetland.

The aim of this study was to determine the enhancement of Scirpus triqueter in the dissipation of pyrene and the interaction of pyrene with plant, soil enzymes and microbial community. The results indicated that the dissipation ratios of pyrene in the rhizospheric and non-rhizospheric soil were 64.65 ± 3.

Degradation of diesel-originated pollutants in wetlands by Scirpus triqueter and microorganisms.

The wetland ecological environment near Huangpu-Yangtze River Estuary (HYRE) is deteriorating more and more seriously due to oil spills. In this paper, the simulation experiment of degradation was conducted to restore the diesel pollution in soils where the decontaminating potential of indigenous hydrocarbon-degrading microorganisms (HDMs) was evaluated with pot experiments and the co-activation between HDMs and native plant, Scirpus triqueter L.(STL), was investigated.
