Characteristics of Organic Matter and DNA in Sediments of Lake Erhai

WEI Zhong qing; LIU Cong qiang; LIANG Xiao bing; WANG Fu shu

The contents of organic carbon and nitrogen were measured and DNA was extracted in the sediments of Lake Erhai. The distribution of organic carbon and nitrogen is consistent, i.e. degradation of organic carbon and nitrogen occurred in 10cm surface sediments and the modes of degradation change at 7cm, resulting in the different characteristics. Using the methods of molecular biology connecting with geochemistry, diagenesis process can be understood deeply.
