Research on the effects of salinity on the microbial community of novel constructed wetland

In this paper, a novel patent intermittent aeration vertical flow constructed wetland (IA-VFCW) was developed, and the influences of salinity on the microbial community of IA-VFCW were investigated. The experimental results showed that bacterial communities at the genus level were transited along with the salinity varied from 0% to 20%. Ferritrophicum and Psychrobacter show an increasing tendency and the maximum abundance was 14.8% and 9.8%, respectively. As salt concentration was increased, Cyanobacteria was gradually disappeared. A total of 8 samples were carried out by microbiology, ten different genera were associated with the removal of nitrogen which included as follows: Halomonas, Thiobacillus, Cyanobacteria, Denitratisoma, Arcobacter, Acinetobacter, Sulfurimonas, Nitrosomonas, Dechloromonas and Hydrogenophaga.
