Molecular Characterization of Wetland Soil Bacterial Communities in Constructed Mesocosms; Master's thesis

摘要

16S rRNA gene analysis was performed on soil samples from a subsurface flow mesosocm experiment, mimicking a constructed wetland. Three typical wetland species of plant were used in nine of the columns and three columns were unplanted controls. Analyses showed that plant presence, plant species, and depth did not have a significant effect on microbial community composition. However, richness analyses illustrated that plant presence had a positive effect on richness, plant species analyses indicated that there was evidence that plant species affected richness in a significant manner, and lastly richness was negatively affected in the bottom depth for the control and Carex comosa communities.
