我国沿海5个地区冬季养殖仿刺参体表微生物多样性比较分析
Comparative analysis of microbial diversity on the skin of Apostichopus japonicus located at five coastal areas of China in winter
摘要
Abstract
Apostichopus japonicus was an important aquatic echinoderm in China,and its surface microorganisms played an important role in the occurrence of diseases of A.japonicus and the interaction with the environment.In this study,Illumina HiSeq high-throughput sequencing technology was used to analyze the diversity of microorganisms on the skin of sea cucumbers in five different coastal areas of China(Dalian,Yingkou,Tangshan,Weihai and Ningde).The results showed that the regional differences had a significant impact on the surface microbial composition of A.japonicus.The skin microorganisms of A.japonicus collected from Ningde(ND)had the most significant difference compared with the other 4 groups.At the phylum level,Proteobacteria was the most dominant phylum in all groups,with the lowest relative richness in ND group(76.16%).At the order and family level,the most dominant microorganisms of ND group belonged to Caulobacterales and Hyphomonadaceae respectively,accounting for 14.48%and 14.34%respectively.At the genus level,the percentage of some microorganisms in ND group were significantly different from other 4 groups(P<0.05),in terms of Acinetobacter,Paracoccus,Lachnospira,etc.In addition,Weihai(WH)group had the highest relative richness at the genus level,with significant difference in Paracoccus percentage(P<0.05).The results of four research would pro-vide a reference for the further study on microbial diversity and environmental adaptation of sea cucumbers,as well as the prevention and treatment of diseases of sea cucumbers.关键词
