Abstract EN
To evaluate effects of environmental conditions on the abundance and communities of three denitrifying genes coding for nitrite (nirK, nirS) reductase and nitrous oxide (nosZ) reductase on the roots of Eichhornia crassipes from 11 rivers flowing into the northern part of Dianchi Lake.
The results showed that the abundance and community composition of denitrifying genes on E.
crassipes root varied with different rivers.
The nirK gene copies abundance was always greater than that of nirS gene on the roots of E.
crassipes, suggesting that the surface of E.
crassipes roots growth in Dianchi Lake was more suitable for the growth of nirK-type denitrifying bacteria.
The DGGE results showed significant differences in diversity of denitrifying genes on the roots of E.
crassipes among the 11 rivers.
Using redundancy analysis (RDA), the correlations of denitrifying microbial community compositions with environmental factors revealed that water temperature (T), dissolved oxygen (DO), and pH were relatively important environmental factors to modifying the community structure of the denitrifying genes attached to the root of E.
crassipes.
The results indicated that the specific environmental conditions related to different source of rivers would have a stronger impact on the development of denitrifier communities on E.
crassipes roots.
