Diversity of dissimilatory bisulfite reductase genes of bacteria associated with the deep-sea hydrothermal vent polychaete annelid Alvinella pompejana.

ABSTRACT: A unique community of bacteria colonizes the dorsal integument of the polychaete annelid Alvinella pompejana, which inhabits the high-temperature environments of active deep-sea hydrothermal vents along the East Pacific Rise. The composition of this bacterial community was characterized in previous studies by using a 16S rRNA gene clone library and in situ hybridization with oligonucleotide probes. In the present study, a pair of PCR primers (P94-F and P93-R) were used to amplify a segment of the dissimilatory bisulfite reductase gene from DNA isolated from the community of bacteria associated with A. pompejana. The goal was to assess the presence and diversity of bacteria with the capacity to use sulfate as a terminal electron acceptor. A clone library of bisulfite reductase gene PCR prod
