The diversity of archaea in deep-sea sediments from the West Philippine Sea Bicol shelf |
| |
| Abstract: | The archaeal diversity and phylogenesis of the sediments samples from the Bicol shelf of the West Philippine Sea for the West Pacific Ocean were analyzed by the 16S rRNA gene clone library method. Totally 465 cloning sequences were obtained and divided into 63 OTUs. Phylogenetic analysis showed that the archaeal sequences were from Crenarchaeota and Euryarchaeota. The majority of the archaeal phylotypes were Marine Benthic Group B (MBGB), Marine Group I (MGI), Miscellaneous Crenarchaeotic Group (MCG), and Marine Benthic Group D. A few sequences fell into Marine Hydrothermal Vent Group (MHVG). The results indicated that the sediment samples of five different layers contained only five groups of archaea. Achaeal community diversity was low, and dominant archaea had some differences in each layers. |
