ferromanganese crust, sandy sediment and overlying seawater were investigated using a
culture-independent molecular analysis based on the 16S rRNA gene. These samples were
carefully collected from the Takuyo-Daigo Seamount, located in the northwest Pacific Ocean,
by a remotely operated vehicle. Based on quantitative PCR analysis, Archaea occupy a
significant portion of the prokaryotic communities in the ferromanganese crust and the …
