Abstract: Cultured-independent molecular analyzing technology was used to construct 16S rRNA gene library and gene sequences of microbial groups for groundwater samples collected at Zhuhai Campus of Sun Yat-sen University and Tangjiawan Town. Microbiological groups were compared to identify the adaption and possible evolution due to urbanization by using the campus as a background. The Proteobacterium, Candidate division OPx and uncultured archaeon(uncultured Crenarchaeote and Euryarchaeote)were found predominant in the recharge, middle and discharge zones of the campus, while none of the uncultured archaeon and Candidate division OPx were found in Tangjiawan. Although microorganism in the groundwater evolves in response to the change from a background with little anthropogenic influence to a urbanized town, linkages of microbial groups between two sites were detected by the genetic neighbor-joining tree, indicating its evolution under a changed environment.

Key words: urbanization, groundwater, microbial group, environmental evolution
