Abstract
Bacterial community structure was compared between two different sediments based on the 16S rRNA sequence analysis by pyrosequencing. The sediment samples were collected from tube worm, Lamellibrachia satsuma, inhabited area (MEGC0044) and caldera region (MEGC0046), which are located at shallow water of marine hydrothermal vent area in Kagoshima Bay, Japan. The phylotypes, the class δ-, ε- and γ-Proteobacteria, and Flavobacteria are predominant in both sediments but the proportion was different. Other phylotypes, Acidobacteria, Chloroflexi, Planctomycetes, and the candidate division WS3, also could be detected by more than 1%. The predominance of δ- and ε-proteobacteria represents distinct characteristics compared with the bacterial community structure previously reported from other cold seeps or hydrothermal vent areas where the γ-Proteobacteria is dominant. The proportion of ε-proteobacteria in MEGC0044 (28.6%) was much higher than that of δ-proteobacteria (14.8%) but vice versa in MEGC0046 by 13.5 and 20.6%, respectively. The results imply that the sulfur oxidizing is major biogeochemical process in MEGC0044, however, MEGC0046 is dominant by the sulfur reducing process. [Supported by MEGRC]
