Microbial Community Structures in the Nam Co Lake,Tibetan Plateau,and Comparison with Other Alpine Lakes
The bacterial diversity and abundance in surface lake water sampled from Nam Co Lake during June, 2006, were analyzed by flow cytomertry and 16S rRNA gene clone library approaches. The bacterial abundance was about 1. 21 × 106 cells · mL-1 in Nam Co, similar to other alpine lakes. Bacteria of β -Proteobacteria were dominant group in Nam Co, accounting for 61% of the total a- mount. The bacteria were similar to others in a-quatic environment, but showed more psychrophil-ic features. Due to different nutrition and geography status, bacterial community in Nam Co is remarkably different from those in Lake Jori XIII in the Alps. Bacteria in Nam Co have lower diversity, and more psychrophilic features than those in Lake Jori XIII.
