Dissolved hydrogen and nitrogen fixation in the oligotrophic North Pacific Subtropical Gyre.

abstract：:We identified an alphaproteobacterium in the digestive gland of the abalone species Haliotis discus hannai. This phylotype dominated our 16S rRNA clone libraries from the digestive gland of H. discus hannai. Diversity surveys revealed that this phylotype was associated with H. discus hannai and also in another host sp...
