Analysis of Microbial Diversity in different periods of Nihewan Using High-throughput Sequencing
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 12
Abstract
Microbial are widely distributed in various ecological environments and play essential roles in the carbon and nitrogen cycles in natural ecosystems. Nihewan site group is wide distribution, rich in content, and covers many subjects of ancient anthropology, paleontology, paleomagnetism, paleoclimatology, etc. At present, domestic and foreign research are concentrated mainly in the Nihewan archaeological value, geological structure, animal and plant community structure. Most community studies have been focusing on settlement of plants and animals but less on microbial succession. In this study, soil samples were collected from different geological Nihewan archaeological strata, and microbial communities were analyzed by HTS technology to reveal bacterial composition. To explore microbial groups in the history of evolution, we collected two soil samples in Nihewan which represent different periods. A total of 1159 OTUs were detected, which could attributed to 197 genera, 167 families, 127 orders，86 classes and 34 phylums of bacteria in NHW1. A total of 905 OTUs were detected, which could attributed to 178 genera, 153 families, 117 orders, 77 classes and 33 Phylums of bacteria in NHW2, and the bacterial communities were different among the two samples.
