Analysis of Bacterial Community Structure and Diversity in Wild Ophicordyceps sinensis

Abstract

Abstract: The bacterial community structure of eight wild Ophicordyceps sinensis were investigated using PCR-DGGE.DNA sequencing was proceeded to obtain dominant bacterial population information in different samples. The result of DGGE profile showed that all the samlples contained abundant bacterial community, different samples have some differences among the Shannon-winner index, Richess and evenness, significant differences were observed between samples from distinct locations. Flavihumibacter petaseus, Sphingomonas aestuarii, Geobacillus pallidus and Methylovirgula ligni were commonly detected in all samples, which laid a foundation for further studying on the roles of bacteria during the formation process of Ophicordyceps sinensis.

Key words: Ophicordyceps sinensis, 16S rRNA, V3, DGGE, Bacterial community
