| Abstract | Microbial diversity in the abyssal sediments beneath the seafloor of 30, 94, and 151 cm near the southern end of the Mariana Trench was analyzed in the Illumina HiSeq 2500 platform. Results show that the microbial populations were dominated by bacteria but merely no archaea were identified at the three depths. In the bacterial community, Proteobacteria and Firmicutes dominated the total taxon tags, followed by Bacteroidetes, Actinobacteria, Planctomycetes, Cyanobacteria, and Chloroflexi, which together account for over 99% of the total population. Similar to that in the seawater in the trench, the operational taxonomic units (OTUs) belonging to Gammaproteobacteria from the sediment samples showed high abundance. However, common bacterial OTUs in the water of the trench including Nitrospirae and Marinimicrobia were hardly found in the sediments from the southern Mariana Trench or the hadal region. Therefore, this study documented for the first time the compositions of microbial diversity in the trench sediments, revealed the difference in microbial diversity in water and sediment of the trench and will enrich the knowledge on the microbial diversity in the abyssal areas. |
